Description

Technical Field

[0001] The invention relates to the field of motor manufacturing, and in particular to an automatic stator winding device for a motor. Background Art

[0002] The motor stator is an important part of motors such as generators and starters. The stator is an important 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 needs to be wound with copper wire on its surface. The prior art CN117175875B discloses a motor stator winding device. By setting a stator fixing component and a push component, the inner top component in the stator fixing component can fix the stator on the rotating shaft. When the rotating shaft rotates, the stator can be driven to rotate, so as to facilitate the adjustment of the coil winding position of the stator. When the output end of the push cylinder contacts the stator, the two output ends of the plug-in adjustment component are inserted into the same gap of the stator, and the angle of the stator is adjusted by the reverse movement of the two output ends, so that the part to be wound of the stator is facing the winding component, avoiding the error caused by the rotation of the fixed rotating shaft, and after the adjustment, the stator and the rotating shaft can be fixed together to avoid the stator or the fixed rotating shaft shaking and affecting the winding of the coil. However, in actual production, it is necessary to perform winding automatically, and it is necessary to improve the efficiency of winding.
