The requirements in this Stan
16、dard supplement or amend the requirements in UL 1004-1. The requirements of UL 1004-1 apply unless modied by this Standard. 1.2 This Standard covers motors that are intended for use in re pump applications as dened by NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection. 1.
17、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, NFPA 70.

19、ss 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 DRIP PROOF A motor intended for indoor use and designed to provide a degree of protection against a limited amount of fallin
20、g 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 motor for the Duty Cycle Test, Section
21、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 and the speed corresponding to the b
22、reakdown 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) moment of inertia as the original
23、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. 2.10 SLIP Dened as Slip Speed divided by Synchronous Speed.

25、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 gyration. The total weight moment
26、 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 accelerate the pump to a given spe
27、ed. 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 Deleted 3.2 Fire pump motors intended for use with variable speed drives shall additionally meet the requirements of
28、the Standard for Inverter Duty Motors, UL 1004-8. 4 Frame and Enclosure 4.1 A re pump motor enclosure shall be rated a minimum of Type 2 (drip proof), IPX2, or higher, or shall be provided with the instructions specied in 12.1 to indicate a Type 2 or equivalent drip proof enclosure is required for t
29、he use environment. PERFORMANCE 5 General 5.1 The voltage of the test circuit for the performance tests shall be at rated voltage unless stated otherwise in the individual tests. 5.2 The tests are capable of being conducted in any order, as long as the Dielectric Voltage-Withstand Test of UL 1004-1
30、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 the sample. It shall be performed after all other tests for that sample have been completed and the motor samp
31、le 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.

32、TION WITHOUT PERMISSION FROM UL 6 Variation from 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
33、 performed on the highest voltage for the 110 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 vol
34、tage. The voltage is then to be reduced to 90 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 un
35、der test delivering full rated mechanical output. 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 evi
36、dence of electrical breakdown as a result of the 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
37、inversely proportional to the voltages. For example, 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 cur
38、rent is to be measured during the rst 3 seconds of the test. After 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 applica
39、tion of the dielectric potential.
