3 Temperature Codes ( T Codes) NEC requires explosion-proof motors to indicate the maximum operating surface temperature. A T Code is used as the temperature identification value and it is taken from the National Electric Code. The T Code is based on the minimum ignition temperature of the substances to be found in the hazardous location. (Ignition temperature is when substance will start to burn or explode) The code, when marked on a motor nameplate, represents the highest temperature that could be obtained on the motor surface under any normal or abnormal operating conditions including locked rotor, single phasing or overloading, and is chosen to be below the ignition temperature of the substance in the hazardous area. The T Code designations apply to motors and other types of electrical equipment subject to hazardous location classification.

5 Motor Selection and Application Safety The use of electric motors, like that of all other utilization of concentrated power, is potentially hazardous. The degree of hazard can be greatly reduced by proper design, selection, installation and use, but hazards cannot be completely eliminated. Some of the factors that must be considered for the safe application of motors are as follows: 1. Enclosure 2. Service conditions 3. Proper matching of the motor to the load 4. Proper sizing and connection to an inverter by qualified technicians Information on these factors is presented in this section. Enclosure The selection of the proper enclosure is vital to the successful safe operation of AC motors. Machine performance and life can be materially reduced by using an enclosure inappropriate for the application. The customer must recognize the specific environmental conditions and specify the correct enclosure. Reliance Electric can provide application assistance, but must depend on the customer to provide accurate information on the operating conditions. Reliance Electric offers motors in the following enclosures: Open Drip-Proof Totally Enclosed (Non-Ventilated, Fan Cooled, Air Over) Explosion Proof Dust Ignition Proof Open Drip-Proof Motor (ODP) An ODP motor is an open machine having all openings limited in size to prevent accidental contact with hazardous parts. Internal parts are protected from drip, splash and falling objects on all horizontal and vertical mounted motors. ODP motors are suitable for general industrial use in indoor locations with relatively clean atmospheres. Totally Enclosed Motor A totally enclosed motor is one so enclosed as to prevent the free exchange of air between the inside and the outside of the case but not sufficiently enclosed to be termed air-tight. Totally enclosed motors are suitable for use in dusty dirty locations and in humid environments. Totally Enclosed Non-Ventilated - Not equipped for cooling by means external to the enclosing parts. Generally limited to low horsepower ratings or short-time rated motors. Totally Enclosed Air-Over - Exterior surface cooled by a ventilating means external to the motor. Customer must provide sufficient air flow to cool motor. Additional protection for motors used in extremely dirty or humid conditions is offered by Reliance mill and chemical duty (XT) features. (IP) Classification of Enclosures The classification system consists of the letters IP (Ingress protection) followed by two numbers. The first number indicates the degree of protection against entry of solid material into the enclosure. The second number indicates the degree of protection against entry of liquids. Table 1: Degree of protection against solid material and personal injury indicated by the 1st numberal Numberal Definition No special protection of persons against accidental or inadvertent contact 0 with live or moving parts or against the ingress of solid material Protection against accidental inadvertent contact with live or moving parts 1 by large surface of a body such as a hand or similar object exceeding 50 mm Protection against accidental or inadvertent contact with live or moving 2 parts by a finger or similar object exceeding 12 mm Entry prevented of tools, wires or other solid objects of a diameter or thickness greater than 2.5 mm 3 Entry prevented of wires, strips or solid objects of a diameter or thickness 4 greater than 1.0 mm Complete protection against contact with live or moving parts inside the 5 enclosure. The entry of dust is not totally prevented, but dust cannot enter in sufficient quantity to interfere with the satisfactory operation of the motor No ingress of dust. Per IEC 34-5 this degree of protection is not applicable 6 to rotating equipment such as motors and generators but applicable to electrical enclosures Table 2: Degree of protection of motors against the harmful ingress of water by the 2nd numberal Numberal Definition 0 No special protection 1 Vertically falling drops 2 Drops falling at any angle up to 15 off of vertical 3 Spray at any angle up to 60 off of vertical 4 Splashed from any direction 5 Projected by nozzle from any direction has no harmful effect 6 Water from heavy seas or projected from powerful water jets has no harmful effect 7 Entry of water in a harmful quantity is prevented when the unit is immersed in water under stated conditions of pressure and time 8 Immersed under water specified pressure for an indefinite time Example - IP54 is met by adding XT features to any totally enclosed motor. TEFC-XT, TEFC-XEC and TEFC-XEX all meet the requirements of IP-54. Totally Enclosed Fan-Cooled - Exterior surface cooled by external fan on motor shaft. Motor cooling is dependent on motor speed.

This is accomplished by limiting the external surface temperature of the motor below the ignition temperature of the hazardous gas or vapor surrounding the motor. Hence it is very important that the end user order a motor with the proper temperature code. Also the enclosure is designed to contain an explosion on the inside of the motor which may be caused by arcing, sparking, or abnormal heat. A flame caused by such an explosion will not propagate the motor fits and ignite the gas or vapor surrounding the motor. An explosion proof motor is suitable for operation in Class I hazardous environment. Dust Ignition Proof - A Dust Ignition Proof motor is a totally enclosed machine designed to operate safely in a flammable dust environment. The motor enclosure prevents the admittance of dust inside the motor. Also the motor is designed to operate cool enough so as not to ignite any dust which might accumulate on the external surface of the motor. Should the motor become blanketed with dust and reduce its normal cooling, winding thermostats will take the motor off line before the motor s external surface temperature reaches the ignition temperature of the hazardous dust. A dust-ignition-proof motor is suitable for operation in a Class II hazardous location. The specific dust or gas present in the hazardous location is identified by the group listing for each Class. Certain Reliance Electric AC motors are listed for use in Class I Groups C and D and Class II Groups E, F and G locations depending on the horsepower rating, frame size and enclosure as indicated on the price pages. The user customer is responsible for insuring that the proper UL listed motor is used in a specific hazardous location. ATTENTION: Misapplication of a motor in a hazardous environment can cause a fire or an explosion and result in serious injury. Only the end user and/or insurance underwriter are qualified to identify the appropriate class(es), group(s), division and temperature code. Reliance Personnel should not render any assistance in identifying the type of environment For hazardous locations in Europe or for ATEX certification or EX mark or flame proof enclosure, contact your local Rockwell Automation sales representative. Service Conditions Standard motors listed in this catalog are designed to operate under the following service conditions. Service conditions exceeding these conditions may require special motor selection or re-rating of standard motors. Altitude - Sea Level to 3300 feet. Ambient Temperature C to 40 C. Mounting - The standard motors listed in this catalog are either foot mounted or have a C-face as indicated on the price pages. The motor must be mounted on a rigid mounting surface for satisfactory operation. Installation - Motor must be in areas or in supplementary enclosures which do not seriously interfere with the ventilation of the motor. Power Supply Phase - Motors are designed for either single-phase or three-phase operation as indicated on the price pages. Single-phase motors may be operated on one-phase of a three-phase power supply with the rated voltage. Operation of a three-phase motor on a single-phase supply will result in motor damage. Voltage Single Phase Motors - standard voltages are 115/230. Three Phase Motors - standard voltage are 190/380, 200, 200/400, 230/460, /460, 460 and 575 as indicated on the price pages. Specific Definite Purpose motors may have other voltages indicated. Motors rated at 230 or 230/460 volts will operate on a 208 volt supply except that starting and peak running torques at 208 volts will be 20-25% less than at the 230 volt rating. Motors nameplated /460 will operate satisfactorily at 208 volts. Voltage Variation - In accordance with NEMA standards, Reliance motors will operate with +10% variation in rated voltage with rated frequency. Performance within this voltage variation will not necessarily be in accordance with performance at rated voltage. Dual Voltage Motors are easily reconnectable by referring to the information on the motor nameplate. Frequency - Motors are designed for operation on 50 or 60 Hz as specified on the price pages. Many motors designed for operation on 60 Hz power may be operated on 50 Hz power of a lower voltage rating with resulting decrease in speed and horsepower. Refer to Reliance Electric for details. In accordance with NEMA standards Reliance Motors will operate with +5% variation in rated frequency with rated voltage. Performance with this frequency variation will not necessarily be in accordance with performance at rated frequency. M-269

7 Insulation Class & Temperature Rise Motor Insulation systems are classified by the maximum total temperature at which the system can be operated without adversely affecting design life. This maximum total temperature has three components. Ambient Temperature = The temperature of the atmosphere in which the motor is operated. 40 C is considered a standard for design purposes. Temperature Rise = Hot Spot Allowance= The number of degrees which the insulated motor windings heat up during motor operation The value that takes into account the additional temperature variations within the inaccessible spots of a motor winding. these spots are located in the stator slots or coil heads. 10 C is considered a standard for design purposes. Four classes of insulation systems are used in motors. In general, the temperature values are as follows: Max Total Components of Max Total Temp. Insulation Temperature Class Temperature Hot 1.0 sf Ambient Rise Allowance A 105 C = 40 C 55 C 10 C B 130 C = 40 C 80 C 10 C F 155 C = 40 C 105 C 10 C H 180 C = 40 C 130 C 10 C Proper Matching of the Motors to the Load General information on the torque/speed characteristics of the various NEMA design classes is given under TORQUE/NEMA DESIGN CLASSES on the following page. The equipment manufacturer and/or user is responsible for selecting the correct motor rating to drive the load. Torque/NEMA Design Classes The full load torque of a motor is expressed as follows: Full load torque (ft. lbs) = Table I. Characteristics of NEMA design classes for squirrel-cage polyphase induction motors NEMA Starting Starting Breakdown Full Load Typical Applications Design Torque Current Torque Slip A Normal High High Low Mach. Tools, Fans B Normal Normal Normal Normal General Industrial C High Normal Normal Normal HP x 5250 Full load speed (rpm) Since different loads present different torque requirements at starting (breakaway), minimum (pull-up), breakdown (pull-out) and full load, the National Electrical Manufacturers Association (NEMA) has defined four standard design classes A,B,C and D of squirrel cage polyphase induction motors. These design classes are summarized in Table I. Loaded Compressor, Loaded Conveyor D Very High Low - High Punch Press or Hoists The general torque/speed relationship with the four torque points defined is shown in Figure 1. The NEMA design class is indicated on each price page in this catalog. Most motors are Design B with a few Design A, C & D. For motors having different characteristics than listed, contact Reliance Electric. Speed/Slip The synchronous speed of an AC motor is as follows Synchronous Speed (rpm) = 120 x Power Supply Frequency (HZ) Number of Poles The number of poles is a function of motor design. Standard 60 Hz motors are available with synchronous speeds of 3600, 1800, 1200 or 900 rpm. The actual operating speed of an AC induction motor is determined by the synchronous speed and the slip. Slip is the difference between the speed of the rotating magnetic field (which is always synchronous) and the rotor speed. Slip generally increases with an increase in motor torque; therefore, actual operating speed generally decreases with an increase in the driven load torque. Figure 1- General Speed/Torque relationship for squirrel-cage polyphase induction motors. Motor torque is defined at four points as shown. 1. Breakaway or starting 2. Minimum or pull-up 3. Breakdown or pull-out 4. Full load Service Factor The service factor of a motor is a multiplier which, when applied to the rated horsepower, indicates a permissible horsepower loading which may be carried under the conditions specified for the service factor.

8 Evaluating Motor Efficiency ANALYZE, COMPARE AND CALCULATE YOUR ENERGY SAVINGS The graphs below show how the Duty Master XE motor efficiency and watts loss curves compare to standard industrial averages. The table below shows the results of these comparisons in terms of annual energy savings.

WATTS SAVED MONEY SAVED $65 1 1/ / , , , , , , , , ,845 As you can see, a 150 HP XE motor could save you $2,831 a year in power costs over standard 150 HP designs, based on electrical costs of $.08 per kilowatt hour and 7200 hours of full load operation per year. The table also shows comparable savings for other motors in the XE motor line. Your actual savings may vary, depending on the electrical rates, load conditions and annual operating hours of your application. In the long term, the decision to invest in an energy efficient Duty Master XE motor depends on the energy savings it can provide. Actual energy savings depend upon many variables including operating hours, cost of power, duty cycles, and line voltages to name a few. Tax rates and the future cost of money will also influence the decision. However, a very simple energy savings calculation can be made to estimate the yearly energy savings with an XE motor. Simple Energy Savings Calculation This simple payback analysis will assume constant full load operation. Note that this calculation ignores the effects of taxes and the time value of money. Later, we ll take partial load and variable duty cycles into account. Information you need to know. HP = Hrs/Yr = $/KWH = XE Eff = STD Eff = Motor full load horsepower Number of hours per year the motor is in operation Cost of electricity in dollars per kilowatt hour XE motor efficiency Standard motor efficiency If actual motor efficiency is unknown, a Reliance sales engineer can help you estimate standard motor efficiencies. First, calculate the kilowatts saved by using the XE motor: 1 Kilowatts Saved = HP x.746 STD - 1 [ XE EFF EFF ] Then, calculate the yearly energy savings: Yearly Savings = Kilowatts Saved x Hrs/Yr x $/KWH M-271

9 Example Assume that a 25 horsepower motor is going to operate for three 8-hour shifts per day, on a 6-day work week, for 50 weeks per year. Thus, total hours per year are Also, assume the cost of electricity at $.08 per kilowatt hour. The savings, using the XE motor with an efficiency of 93%, compared to the 88% which is the industry average for a standard efficient motor, is calculated as follows Kilowatts Saved = HP x.746 n this case, the yearly savings is $ In other words, if you wanted a one-year payback on your investment, you could afford to spend $656 more for the XE energy efficient motor than for a standard efficient motor. Duty Cycles Many people question the energy savings of partial load or variable duty cycle applications. The energy saving equations are the same. However, when evaluating a partial load operation, remember to use the horsepower, efficiency, and appropriate hours of operation at the desired load point. A variable duty cycle calculation is simply the summation of several partial load calculations. Additional Savings This payback analysis also does not take into account many additional savings you should consider. Longer motor life as a result of cooler operating temperatures Additional cost savings from improved power factor Improved partial load efficiencies of the XE motor Improved reliability with a more forgiving electrical design Quieter operation = 25 x.746 = Kilowatts Saved Yearly Savings = Kilowatts Saved x Hrs/Yr x $/KWH = x 7200 x.08 = $ [ - STD EFF ] Greater flexibility for use on adjustable frequency power supplies This is why so many companies specify Reliance Duty Master XE energy efficient motors for all their applications XE EFF Useful Formulas Electrical Alternating Current To Find Single Phase Three Phase Amperes when horsepower HP x 746 HP x 746 is known E x Eff x pf 1.73 x E x Eff x pf Amperes when kilowatts are Kw x 1000 Kw x 1000 known E x pf 1.73 x E x pf Kva x 1000 Kva x 1000 Amperes when kva are known E 1.73 x E Kilowatts Kva Horsepower = I x E x Eff x pf 1.73 x I x E x Eff x pf (Output) I = Amperes: E = Volts; Eff = Efficiency; pf = Power factor; Kva = Kilovolt-amperes; Kw = Kilowatts I x E x pf I x E 1.73 x I x E x pf 1.73 x I x E HP/Torque/Speed For Rotary Objects Torque in Lb. ft = For Objects In Linear Motion Speed HP = RPM= Inertia Loads t = t = FV 33,000 HP x 5250 rpm 120 Frequency No. of Poles HP= Torque x rpm 5250 Where F = Force (lbs.)
