The requirements in this Standard supplement or amend the requirements in UL 1004-1. The
16、requirements of UL 1004-1 apply unless modied by this Standard. 1.2 This Standard covers Design B polyphase motors, as dened in NEMA MG 1, Motors and Generators, rated 500 horsepower (373 kW) or less, 600 volts or less, that are intended for use in accordance with NFPA 20, the Standard for the Insta
17、llation of Centrifugal Fire Pumps. 1.3 This Standard does not cover the re pump controller. These controllers are covered by the Standard for Fire Pump Controllers, UL 218. 1.4 These requirements do not cover motors intended for use in hazardous locations as dened in the National Electrical Code, NF
18、PA 70. The National Electrical Code and NEC are registered trademarks of the National Fire Protection Association, Inc., Quincy, MA 02169. 2 Glossary 2.1 For the purpose of this Standard, the following denitions apply. 2.2 BREAKDOWN TORQUE Maximum torque developed when a motor is run at rated voltag
19、e and frequency, without an abrupt loss in speed. 2.3 DESIGNBAsquirrel-cage motor designed to certain minimum torque values and a maximum locked-rotor current with a slip of less than 5 percent at rated load. 2.4 DRIPPROOF A motor intended for indoor use and designed to provide a degree of protectio
20、n against a limited amount of falling water and dirt. 2.5 LOCKED-ROTOR TORQUE Minimum torque developed when a motor with the rotor locked is operated at rated voltage and frequency. 2.6 MODELING A process to simulate an actual load under laboratory conditions. This is usually used when testing a mot
21、or for the Duty Cycle Test, Section 9. The loading device may have more severe starting conditions than the re pump. In order to avoid overheating the motor during testing, it is required to reduce the number of starts and stops. 2.7 PULL-UP TORQUE Minimum torque developed at any speed between zero
22、and the speed corresponding to the breakdown torque, when the motor is operated at rated voltage and frequency. 2.8 RADIUS OF GYRATION The distance from an axis that one could put a single particle of weight equal to the weight of a rigid body and have this particle have the same total weight (force
23、) moment of inertia as the original body. The radius of gyration is expressed in the units of distance (meters or feet) squared, i.e., m 2 or ft 2 . 2.9 SLIP SPEED The difference between the synchronous speed and the measured speed of a motor.

24、 MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 2.10 SLIP Dened as Slip Speed divided by Synchronous Speed. 2.11 SYNCHRONOUS SPEED (of a motor) Dened by the equation, h s = 120 f/p in which: h s = the synchronous speed in revolutions per minute f = the li
25、ne frequency in hertz p = the number of motor poles 2.12 TOTAL WEIGHT (FORCE) MOMENT OF INERTIA The total weight moment of inertia is a measure of the distribution of the weight of an object relative to a given axis. The total weight moment of inertia is the product of weight times the radius of gyr
26、ation. The total weight moment of inertia, “I”, is the expressed in units of distance squared times weight (or mass), i.e., kgm 2 or lbft 2 . In the case of a re pump, it is a characteristic of the pump which will dictate the amount of time, “t”, that it will take a motor with a torque, “T”, to acce
27、lerate the pump to a given speed. Conversely, it is a characteristic that will dictate the amount of time that a given pump, coupled to a given motor, will take to decelerate to a stop. CONSTRUCTION 3 General 3.1 A motor for use with re pumps shall be polyphase Design B, as dened in NEMA MG 1, Motor
28、s and Generators. 3.2 Fire pump motors intended for use with variable speed drives shall additionally meet the requirements of NEMA MG-1, Motors and Generators, Part 31, Denite Purpose Inverter Fed Polyphase Motors. 4 Frame and Enclosure 4.1 A re pump motor enclosure shall be rated a minimum of Type
29、 2, Dripproof, or shall be provided with the instructions specied in 12.1 to indicate a Type designation required for the use environment. The Type designation shall be in accordance with the Standard for Enclosures for Electrical Equipment, Environmental Considerations, UL 50E. MAY 9, 2014 FIRE PUM

31、s are capable of being conducted in any order, as long as the Dielectric Voltage-Withstand Test of UL 1004-1 is conducted on a motor in a heated condition. 5.3 When a single motor sample is used for several or all tests, only one Dielectric Voltage-Withstand Test of UL 1004-1 shall be performed on t
32、he sample. It shall be performed after all other tests for that sample have been completed and the motor sample is in a heated condition. When a single motor sample is used for each test, the Dielectric Voltage-Withstand Test of UL 1004-1 shall be performed as required on each sample. 6 Variation fr
33、om Rated Voltage Test 6.1 An induction re pump motor shall operate when subjected to a voltage of 10 percent higher and 10 percent lower than the nameplate voltage for each voltage rating. For motors with a voltage range, the test specied in 6.2 shall be performed on the highest voltage for the 110
34、percent test and the lowest voltage for the 90 percent test. 6.2 One sample of a re pump motor is to be connected to a source of supply and loaded to rated horsepower, times any rated service factor. The motor is to be operated at rated frequency and voltage. The voltage is then to be reduced to 90
35、percent of the rated voltage and operated for one minute. The voltage is then to be increased to 110 percent of the rated voltage and operated for one minute. 7 Temperature Test 7.1 The Temperature Test of UL 1004-1 is to be conducted with the machine under test delivering full rated mechanical outp
36、ut. This test is then to be repeated with the machine under test delivering full rated mechanical output, multiplied by any service factor if provided. 8 Locked Rotor Test for Fire Pump Motors 8.1 A re pump motor shall continue to operate and show no evidence of electrical breakdown as a result of t
37、he locked-rotor current evaluation specied in 8.2. The current measured during the test shall not exceed the values in Table 8.1 for 60 Hz motors and Table 8.2 for 50 Hz motors. For voltages other than 230 or 380 volts, the locked-rotor current shall be inversely proportional to the voltages. For ex
38、ample, for a 115-volt motor, the maximum locked-rotor current at a given horsepower rating is twice the maximum value at 230 volts. 8.2 One sample of the motor is to be operated for 12 seconds at rated voltage and frequency with the rotor locked. The current is to be measured during the test. After
39、the locked-rotor operation, and while still in a heated condition, the motor shall be subjected to the Dielectric Voltage-Withstand Test of UL 1004-1 without evidence of electrical breakdown. The motor shall operate after the application of the dielectric potential. MAY 9, 2014 FIRE PUMP MOTORS - UL
