摘　　要：应用于游梁式抽油机上的三相永磁同步电动机存在转子温度过高而导致转子失磁的现象,针对这一现象,需要对转子温度进行检测。介绍了永磁电机转子温度测试仪的硬件电路和软件设计,该仪器成本低且易于携带,具有一定的应用价值。After the three mutually synchronous permanent magnet machine applied in the beam pump, the phenomenon of temperature rising quickly has appeared ture examination was needed. In this paper, the hardware and For this phenomenon, the temperasoftware design of the temperature measurement instrument for the rotor of permanent magnet machine are introduced. The instrument can be widely used due to its many desirable properties such as low cost and portable.
