17、ON WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 This Standard is intended to be read together with the Standard for Rotating Electrical Machines General Requirements, UL 1004-1. The requirements in this Standard supplement or amend the requirements in UL 1004-1. The requirements of UL 1004-1

18、apply unless modied by this Standard. 1.2 This Standard applies to squirrel cage polyphase induction motors intended for use with variable voltage and variable frequency controls, commonly referred to as inverters. The requirements in this Standard are intended to evaluate the suitability of the mot

19、or for normal use when fed from an inverter supply through a manufacturer declared range of operating conditions. 1.3 This Standard does not address: a) The efficacy of motor overtemperature protection under abnormal conditions; b) The operation of a motor under unusual service conditions as describ

20、ed in NEMA MG-1, Standard for Motors and Generators, Part 31; nor c) The operation of a motor in hazardous (Classied) locations. 2 Glossary 2.1 For the purpose of this Standard, the following denitions apply. 2.2 BASE RATING (MOTOR) The rating (i.e., torque, horsepower, speed, current, etc.) measure

21、d at the upper end of the constant torque range (operating point 3 of Figure 8.1) of the motors torque/speed curve. This is the rating to be used for the required motor markings specied in Section 9, General. 2.3 BREAKAWAY TORQUE The torque produced at zero speed, also known as starting torque or lo

22、cked rotor torque. 2.4 BREAKDOWN TORQUE The maximum torque before a sudden loss of speed.

23、s Standard shall be so constructed that, in an emergency not to exceed 2 minutes, they shall withstand without mechanical damage or without posing a risk of electric shock or re, overspeeds above the maximum declared operating speed in accordance with Table 3.1. Table 3.1 Overspeeds Maximum declared

24、 operating speed Overspeed percent of maximum declared operating speed 1800 and below 25% 1801 3600 20% 3601 and over 15% PERFORMANCE 4 Declared Operating Point Temperature Test 4.1 Temperature tests shall be conducted at representative dened operating points, typically one at each of the four opera

25、ting points declared by the manufacturer in accordance with 8.2. 4.2 Since not all motors have four dened operating points, in such cases, the required temperature tests are to be reduced to the number of dened points declared by the manufacturer. 4.3 Each temperature test is to be conducted and res

26、ults evaluated as specied in 32.2 32.11 of UL 1004-1. 5 Breakaway Torque 5.1 The motor under test is to be coupled to an instrument or device suitable and capable of measuring and displaying torque and to an instrument capable of measuring locked rotor current. The breakaway torque and current are t

27、o be measured. 5.2 The breakaway torque shall be at least 140 percent of the base torque and the current at that torque shall be not more than 150 percent of the base current.

28、IBUTION WITHOUT PERMISSION FROM UL 6 Breakdown Torque 6.1 The motor under test is to be coupled to a dynamometer suitable and capable of measuring and displaying torque and to a variable frequency, variable voltage source of sufficient current rating to provide the current required at 150 percent ra

29、ted torque at each test frequency. 6.2 The breakdown torque at any frequency within the dened frequency range shall not be less than 150 percent of the rated torque when rated voltage for that frequency is applied. 7 Overspeed Test 7.1 The motor is to be driven to an overspeed consistent with its ma

30、ximum rated speed and in accordance with Table 3.1. The motor is to be maintained at that speed for 2 minutes and then allowed to coast to a stop. 7.2 A dielectric voltage withstand test in accordance with Section 37, Dielectric Voltage-Withstand Test, of UL 1004-1 is to be applied. 7.3 At the concl

31、usion of the dielectric voltage withstand test, the motor is to be disassembled and examined for evidence of mechanical damage or failure. 7.4 The motor shall not exhibit either a dielectric breakdown as a result of the test described in 7.2 nor shall it exhibit evidence of mechanical damage or fail
