Description

Technical Field

[0002] The motor stator is an important component of the servo motor. At present, the servo motor stator is generally a block type, that is, the motor stator body is composed of multiple motor stator parts, the motor stator parts are detachably connected to each other, and each motor stator part is provided with a winding column.

[0003] When testing the internal resistance and insulation of the above-mentioned servo motor stator, the following method is usually used: the operator uses an internal resistance meter to contact two probes to the two winding poles of the motor stator, and reads the internal resistance value through the display screen, and then the operator manually determines whether it is qualified. The stator insulation detection method also uses a similar method, manually wiring to obtain the test data, and then uses the pre-set values ​​on the detection instrument to verify whether the stator will have poor withstand voltage under this voltage. If it is poor, the detection instrument will make a sound prompting that the test failed. The manual detection of the internal resistance and insulation of the servo motor stator has certain instability and may result in misjudgment. In addition, since the withstand voltage inspection is dangerous, there are safety hazards in using manual detection. Utility Model Content
