Description

Technical Field

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

[0002] The stator is the stationary part of the motor. The stator consists of three parts: the stator core, the stator winding and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by the magnetic lines of force in the rotating magnetic field to generate (output) current. The stator winding is the circuit part of the motor, which is connected to a three-phase alternating current to generate a rotating magnetic field. It is a general term for a single phase or the entire electromagnetic circuit composed of multiple coils or coil groups. According to the shape of the coil winding and the embedded wiring method, it can be divided into centralized and distributed types. The winding and embedding of centralized windings are relatively simple, but the efficiency is low and the operating performance is also poor. Most of the stators of AC motors use distributed windings. According to different machine types, models and coil embedding process conditions, the motors are designed with different winding types and specifications.

[0003] The stator winding machine is a mechanical device used to produce the stator winding of the motor, that is, to wind the coil on the stator of the motor. The working principle of the stator winding machine is to use mechanical movement to wind the wire on the stator core according to certain rules and process requirements, thereby completing the winding of the motor.

[0004] The stator winding fixture is a fixture used to fix and position the stator core, and is an important auxiliary tool for the stator winding machine. Its function is to ensure the stability and accuracy of the stator core during the winding process to ensure the uniform distribution and dimensional accuracy of the winding. When winding, the stator core is inserted into the winding frame, and then the winding frame is fixed to the winding machine through the winding fixture.

[0005] Existing stator winding fixtures can usually only clamp stator cores and winding bobbins of fixed sizes. The signal of the winding bobbin matches the stator core, and the scope of application is small. The production of stators of different models and specifications requires different fixtures to adapt to winding bobbins of different sizes. The process of replacing the fixture is partially troublesome. Utility Model Content
