摘要

虽然关于新的NEMA设计“E”电机本身的大量信息已经发布，但很少注意到用于控制它们的相关设备。本文首先讨论了电机设计和相关主题，然后转移到设计E电机目前的控制和保护装置与他们一起使用的独特问题。涉及的问题包括:NEMA Design E电机的特性;1997年联邦法令对节能电机的影响;用于NEMA Design E电机的控制和保护设备的UL和NEC规定;在E型电机上使用时，可能会出现过载继电器和瞬时断路器的麻烦跳闸。

NEMA Design E motors and controls

While considerable information has been published on the new NEMA design "E" motors themselves, little attention has been given to the associated equipment used to control them. This paper first discusses the motor design and related topics and then moves to the unique issues that Design E motors present to the control and protection devices used with them. Issues to be covered include: the characteristics of NEMA Design E motors; the impact of the 1997 Federal Mandate on energy efficient motors; UL and NEC ramifications on control and protection equipment for use with NEMA Design E motors; and the potential for nuisance tripping of overload relays and instantaneous circuit breakers when used on Design E motors.
