21、s 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/electronic protector combination is changed, th
22、e 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 Standard for Thermally Protected Motors, UL 1004

All rights reserved. 3.3 PROTECTION SCHEME A combination of sensing and control circuits. Examples include the following: a) A
30、 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 sensing and a control circuit designed to take
31、 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 protection scheme or schemes relied upon t
32、o provide freedom from motor overheating due to the causes described in 6.6 (a) (d) shall be identied and then validated through test and evaluation to either: a) The Standard for Automatic Electrical Controls for Household and Similar Use, Part 1: General Requirements, UL 60730-1; or b) The UL 6033
33、5-1 based requirements in Sections 8A 8I. 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, that are no
34、t relied upon to provide freedom from motor overheating, shall only be evaluated as operating circuits not as protective circuits.

35、STRUCTION 5 Spacings 5.1 Spacings at an electronic protector terminal intended to be used as a eld-wiring terminal shall not be less than those specied in Table 18.1 or Table 18.2 of UL 1004-1, as appropriate. 5.2 The adequacy of spacings shall reect the actual levels of voltage involved, which in t
36、he 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 Standard for
37、 Automatic Electrical Controls for Household and Similar Use, Part 1: General Requirements, UL 60730-1, on the control is to be performed with the control connected as intended to the motor. Exception: A motor control shall only need comply with the requirements for operating controls in UL 60730-1,
38、 if the motor coil complies with the locked rotor performance criteria in the Standard for Thermally Protected Motors, UL 1004-3, with motor control disconnected from the motor coils, and the power supply for the motor control connected directly across a single motor coil or any combination of motor
39、 coils connected in parallel. 6.2 Any test conducted on the control that does not result in an obvious inability 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 32.2 of UL
40、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 of the motor to operate as intended, characterized by a cessation of rotation, shall not result in a temperature of the motor windings in
41、 excess of the values specied in Table 41A.1 of UL 1004-3. Cessation of rotation is considered to be independent of an inability to start. 6.4 Any abnormal test conducted on the electronic protection circuit that terminates as a result of a component failure, that failure mode shall be evaluated in
42、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 evaluated to the requirements of UL 60730-1: a) Locked
43、rotor protection The control shall not allow motor temperatures in excess of those specied in Table 41A.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 a power supply phase does not result in a cessation of rotat
44、ion, the temperature of the motor windings shall not exceed the values specied in Table 41C.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 exceed the values specied in Table 41A.1 of UL 1004-3.
