Description

Technical Field

[0001] The utility model relates to the field of motors, in particular to a motor stator tester. Background Art

[0002] The motor stator is the stationary part of the motor. The stator is an important part of the motor. The main function of the stator is to generate a rotating magnetic field. The stator consists of three parts: the stator core, the stator winding and the frame. The stator core is generally made of silicon steel sheets punched and stacked. The stator core is also the part where the winding is placed. The motor stator frame is set on both sides of the stator core. However, the motor stator assembly is a semi-finished product and cannot be tested separately. It belongs to the motor composed of other parts and tested together. This easily leads to the need to disassemble the entire product once a problem is found, which is time-consuming and labor-intensive, and it is also easy to increase costs. For this reason, a motor stator tester is proposed. Utility Model Content
