17、ended 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 Motors covered by this Standard,

18、whose overheating protection is provided by an electronic circuit, shall additionally comply with the requirements contained in the Standard for Thermally Protected Motors, UL 1004-3, with regard to Construction, Performance, Manufacturing and Production Tests, Markings, and Instructions unless modi

19、ed by this Standard. 1.3 This Standard applies to motors that rely upon an electronic circuit to prevent overheating of the motor. 1.4 The requirements in this Standard are intended to evaluate a specic motor/electronic protector combination. When the motor, the electronic protector, or the motor/el

20、ectronic protector combination is changed, the combination shall be reevaluated. 1.5 The requirements in this Standard do not cover sealed (hermetic) type compressor motors. 1.6 This Standard does not apply to motors that comply with the Standard for Impedance Protected Motors, UL 1004-2, or the Sta

21、ndard for Thermally Protected Motors, UL 1004-3, independent of the electronic circuit. 2 Components 2.1 Controls used to provide overheating protection for motors covered by this Standard shall comply with the requirements for protective controls contained in the Standard for Automatic Electrical C

22、ontrols Part 1: General Requirements, UL 60730-1, or the applicable requirements in Sections917. 3 Glossary 3.1 For the purpose of this Standard, the following denitions apply. 3.2 INTENTIONALLY WEAK PART A part intended to rupture under conditions of abnormal operation to prevent the occurrence of

All rights reserved. 3.6 PROTECTION SCHEME A combination of sensing and control circ

28、uits. Examples include the following: a) A combination of rotation sensing (i.e., Hall effect sensor) and a control circuit designed to take corrective action (i.e., deenergize the motor in the event that the Hall effect sensor senses a lack of intended motor speed); b) A combination of current sens

29、ing and a control circuit designed to take corrective action in the event that excessive motor current is detected. Electronic protection circuits may incorporate one or many protection schemes to provide primary or redundant overheating protection for a motor. 4 Application of Requirements 4.1 The

30、protection scheme or schemes relied upon to provide freedom from motor overheating due to the causes described in 6.5 (a) (c) shall be identied and then validated through test and evaluation to either: a) The Standard for Automatic Electrical Controls Part 1: General Requirements, UL 60730-1; or b)

31、The UL 60335-1 based requirements in Sections917. 4.2 Protection scheme(s) provided but not relied upon to provide freedom from motor overheating shall be disabled during evaluation and testing of the scheme(s) described in 4.1. 4.3 The circuitry associated with those scheme(s) described in 4.2, tha

32、t are not relied upon to provide freedom from motor overheating, shall only be evaluated as operating circuits not as protective circuits.

34、ich in the case of electronically protected motors may be signicantly greater or less than the nominal power line voltage. PERFORMANCE 6 Application of UL 60730-1 to Controls used to Provide Overtemperature Protection for Motors 6.1 With reference to 2.1, all performance testing required by the Stan

35、dard for Automatic Electrical Controls Part 1: General Requirements, UL 60730-1, on the control is to be performed with the control connected as intended to the motor. 6.2 Any test conducted on the control that does not result in an obvious inability of the motor to operate as intended, characterize

36、d by a cessation of rotation, shall not result in a temperature of the motor windings in excess of the values specied in Table 32.1 of UL 1004-1. Cessation of rotation is considered to be independent of an inability to start. 6.3 Any test conducted on the control that results in an obvious inability

37、 of the motor to operate as intended, characterized by a cessation of rotation, shall not result in a temperature of the motor windings in excess of the values specied in Table 8.1 of UL 1004-3. Cessation of rotation is considered to be independent of an inability to start. Exception: Any test condu

38、cted on the control used within a motor intended for eld installation shall not result in a temperature of the motor windings in excess of the values specied in Table 32.1 of UL 1004-1. 6.4 Any abnormal test conducted on the electronic protection circuit that terminates as a result of a component fa

39、ilure, that failure mode shall be evaluated in a manner consistent with the requirements of UL 60730-1 to ensure that the result is reliable and consistent. 6.5 Controls evaluated to provide required motor overtemperature protection shall provide the following required safety functions when evaluate

40、d to the requirements of UL 60730-1: a) Locked rotor protection The control shall not allow motor temperatures in excess of the applicable values specied in Table 8.1 of UL 1004-3 under any test condition required by UL 60730-1. b) Loss of phase (power supply phase not motor phase): 1) Where loss of

41、 a power supply phase does not result in a cessation of rotation, the temperature of the motor windings shall not exceed the applicable values specied in Table 10.1 of UL 1004-3. 2) Where loss of a power supply phase results in a cessation of rotation, the temperature of the motor windings shall not

42、 exceed the applicable values specied in Table 8.1 of UL 1004-3.
