15、cope 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 apply unless modied by this Standard. 1.2 This

16、 Standard applies to servo and stepper motors. The requirements in this Standard are intended to evaluate the suitability of the motor for normal use when fed from an appropriate controller (drive) through its manufacturer declared normal operating region. 1.3 This Standard does not address: a) The

17、efficacy of motor overtemperature protection under normal or abnormal conditions; nor b) 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 CONTINUOUS STALL CURRENT A maximum value of current specied by the

18、manufacturer which when conducted by the motor windings under stalled (locked-rotor) conditions will not cause motor temperature to exceed its rated temperature rise. 2.3 HOLDING TORQUE The maximum static torque that can be applied to the shaft of a stepping motor, excited with rated current, withou

19、t causing rotation. 2.4 PULLOUT TORQUE The maximum torque that a stepper motor is capable of delivering at a given speed before slipping out of synchronization. 2.5 SERVO MOTOR A motor specially designed and built, having a high speed of response and designed for use in a feedback control system, ty

20、pically for precision positioning. 2.6 SOAC A curve on a servo motor torque/speed chart, which denes the limit of the Safe Operating Area for Continuous operation for the given motor. 2.7 STEPPING (STEPPER) MOTOR An electromagnetic machine designed to convert a series of input electrical pulses into

21、 a series of discrete mechanical angular movements. When not slewing, the machine maintains a discrete holding position.

22、and Temperature Tests 3.1 General 3.1.1 This Section replaces 31.2 and 32.1 in UL 1004-1. 3.2 Servo motors 3.2.1 The Rating and Temperature Tests are to be conducted at two points on the SOAC curve: a) Maximum torque and zero speed; and b) Maximum torque and maximum speed. 3.2.2 In each case, the mo

23、tor shall deliver rated torque and speed with the input current not varying from the marked input current rating by more than 10 percent, and the temperatures on materials and components shall not exceed the values specied in the Maximum Temperatures Table (Table 32.1) of UL 1004-1. 3.2.3 At the man

24、ufacturers option, the Rating and Temperature Tests may be repeated to verify operation at the two points on the SOAC curve corresponding to supplementary forced cooling and/or heatsinking. 3.3 Stepper motors 3.3.1 The Rating and Temperature Tests are to be conducted at maximum torque and zero speed

25、 (holding) in accordance with the manufacturer declared operating performance envelope. 3.3.2 In each case, the motor shall receive maximum-phase excitation at full rated voltage and current. 3.3.3 In each case, the motor shall deliver rated torque and speed with the input current not varying from t

26、he marked input current rating by more than 10 percent, and the temperatures on materials and components shall not exceed the values specied in the Maximum Temperatures Table (Table 32.1) of UL 1004-1. If the manufacturers specications require the use of a specied heatsink, the specied heatsink shal

27、l be used in conducting the Rating and Temperature Tests.

28、 in 44.1 (a) (d) and (g) of UL 1004-1. It is additionally required to have the following markings provided either on the motor or on the smallest packaging: a) Continuous stall current; and b) Maximum rotational speed. 4.2 A stepper motor is required only to bear the markings described in 44.1 (a) (

29、d), (g), and (h) of UL 1004-1. It is additionally required to have the following markings provided either on the motor or on the smallest packaging: a) Holding torque; and b) Maximum rotational speed. INSTRUCTIONS 5 General 5.1 The required information specied in 5.2 5.4 shall be provided in the ins

30、tructions or specication sheets provided with the product. 5.2 Manufacturers of servo and stepper motors shall provide applicable specications and charts of declared motor operating performance. 5.3 In the case of servomotors, this shall include a torque vs. speed chart indicating the SOAC curve for

31、 the motor as well as, at the manufacturers option, boundaries of safe continuous operation using an external blower and/or heatsink. An example of such a chart is shown in Figure 5.1.
