摘要

感应电动机需要热保护，以防止过热循环以及稳态过载。本文讨论了客户在对电机继电器进行测试时，在不使电机过热的循环载荷作用下过早跳闸的问题，并对其特性曲线进行了分析。

Understanding service factor, thermal models, and overloads

Induction motors require thermal protection to prevent overheating to cyclic as well as steady state overloads. This paper discusses the problem that occurred while a customer was testing the motor relay that trip prematurely when subjected to cyclic loads that do not overheat the motor and the characteristic curves are analyzed.
