The invention discloses a stator coil reverse fast detection device and detection method, comprising a support platform, a motor fixed on the lower surface of the support platform, a power output shaft of the motor is connected with a coupling, and a coupling is opened on the support platform. A shaft coupling hole, the shaft coupling passes through the shaft coupling hole and extends above the upper surface of the supporting table, the free end of the coupling is fixed with a two-way Hall sensor, and the upper surface of the supporting table is fixed There is a reset switch, a protruding structure is fixed on the coupling, and a supporting ring frame for supporting the stator coil is fixed on the upper surface of the supporting platform around the coupling hole. The sensors are respectively electrically connected to the controller. The detection device of the present invention judges the information of the magnetic field of the stator coil by analyzing the waveform of the electric signal, and then can detect whether the stator coil is installed reversely. The detection device has a simple structure and can directly detect the stator coil. problems, detection is quick and easy.
Description
technical field [0001] The invention belongs to a stator coil detection device, and in particular relates to a fast detection device and a detection method for reversed stator coil installation. Background technique [0002] During the production process of asynchronous motors, due to the mistakes of production workers, all or part of the stator windings may be reverse-embedded, or the wiring of the windings may be wrong. The current is larger, and the motor makes abnormal noise and vibrates violently. If the power is not cut off and shut down in time, the motor speed will drop, and the stator winding of the motor will be burned soon. [0003] The stator winding is the main component of the motor, and it is also the most vulnerable part of the motor to cause failure. In actual application of existing detection methods, it is often necessary to dismantle the motor in production applications, or wait until the motor fails to find the winding error. The detection method is m...
