Method and system for detecting motor stator temperature, and motor

The invention discloses a method and system for detecting motor stator temperature, and a motor. The method includes arranging at least one stator test point on an end part and/or side part of a stator, and arranging an installing hole in an end cover and/or enclosure of a motor corresponding to the position of each stator test point; installing and fixing a noncontact temperature sensor on the end cover/enclosure of the motor through the installing hole, and controlling the distance between the noncontact temperature sensor and the corresponding stator test point within a preset distance range; and according to temperature data of the stator test point collected by the noncontact temperature sensor, performing real-time detection of the temperature of the stator. The method provided by the invention realizes noncontact detection of the temperature of the stator. 本发明公开了种检测电机定子温度的方法、系统和电机。该方法包括：在定子的端部和/或侧部设置至少个定子测试点，在电机的端盖和/或机壳上对应每个定子测试点所在的位置设置个安装孔；将非接触式温度传感器通过安装孔安装固定在电机的端盖和/或机壳上，控制非接触式温度传感器与对应定子测试点之间的距离在预设距离范
