Abstract

The invention provides a detecting device for a servo motor stator. The detecting device for the servo motor stator comprises a first feeler pin assembly, a stator platform assembly and a detecting control unit. A platform used for placing a stator to be detected is arranged on the stator platform assembly, the first feeler pin assembly comprises a first support and a plurality of first feeler pin groups installed on the first support, A first end of each feeler pin group is respectively used for being connected with one group of winding posts in the stator to be detected, and a second end of each feeler pin group is connected with the detecting control unit. The detecting control unit is used for sequentially detecting a resistance value between each two first feeler pins of each first feeler pin group, and discontinuing detecting when the detected value exceeds a preset value. The invention further provides a corresponding detecting technology. Due to the facts that the plurality of first feeler pin groups connected with the multiple groups of winding posts of the stator to be detector are respectively detected in sequence and according to the preset value, the detection is automatically judged whether to be normal or not, the internal resistance detection of the servo motor stator is achieved efficiently and accurately.

Description

technical field [0001] The invention relates to the field of servo motors, more specifically, to a device and process for detecting internal resistance and insulation of a servo motor stator. Background technique [0002] Since servo motors can achieve precise control of speed and position, they are widely used in CNC machine tools, printing and packaging machinery, textile machinery, automated production, and other equipment that require relatively high process accuracy, processing efficiency, and work reliability. [0003] The motor stator is an important part of the servo motor. At present, the stator of the servo motor is generally of block type, that is, the motor stator body is spliced ​​by multiple motor stator splits, and the motor stator splits are detachably connected to the motor stator splits. Set up winding posts. [0004] The above-mentioned servo motor stator internal resistance and insulation testing usually adopts the following method: the operator uses an...
