Three-phase AC motor stator winding coil mismatched wiring detection apparatus and the detection method

Abstract

The invention belongs to the technical field of motor detections, in particularly, a three-phase AC motor stator winding coil mismatched wiring detection apparatus and the detection method. The apparatus comprises an insulation work bench, a stator core on the insulation work bench, a three-phase winding power wire and an alternate power source in connection with the three-phase winding power wire. The inner round surface of the stator core is provided with a winding coil. The other end of the three-phase winding power wire in connection with the alternate power source is attached to the surface of the winding coil to form a rotary magnetic field. The winding coil is provided with a squirrel-cage type thin wall rotor detection component. There is some gap between the squirrel-cage type thin wall rotor detection component and the winding coil and the squirrel-cage type thin wall rotor detection component can rotate and move in the circumferential direction of the winding coil in a sliding manner. The three-phase AC motor stator winding coil mismatched wiring detection apparatus and the detection method provided by the invention are cost-effective and easy to operate. Prior to a dip coating process, it is possible to detect whether a stator core with a winding coil is wired correctly or not.

Description

Technical field [0001] The invention belongs to the technical field of motor detection, in particular to a three-phase AC motor stator winding coil wiring error detection device and detection method. Background technique [0002] Most of the existing motor stator off-line technologies use manual winding, off-line, and end wiring processes, and off-line wiring errors are unavoidable in the manufacturing process. Especially for large and medium-sized motor stators, there are more slots and more stator coils; when individual coil wiring errors occur, it is difficult to detect them in time. If it is detected that a certain coil has a problem after the overall dipping process of the stator core with windings, all the coils of the motor can only be scrapped, resulting in serious material waste, and the maintenance process of the stator core with windings after dipping is very complex. For this reason, it is necessary to design a device that can complete the coil wiring error detectio...

Problems solved by technology

[0002] Most of the existing motor stator off-line technology adopts manual winding, off-line, and end connection processes, and it is inevitable that there will be errors in off-line wiring during the manufacturing process

Especially for large and medium-sized motor stators, the number of slots is large and the number of stator coils is large; when individual coil wiring errors occur, it is difficult to detect them in time

If it is detected that there is a problem with a certain coil after the overall varnish dipping process of the stator core with winding, all the coils of the motor can only be scrapped, resulting in serious waste of materials, and the overhaul process of the stator core with winding after varnish is very difficult. complex
