Description

Technical Field

[0001] The invention relates to the technical field of flat wire motor stator production, and in particular to an axial flux flat wire motor stator twisting device and method. Background Art

[0002] Flat wire motors are usually composed of stators, rotors, reducers, etc., and the stator of a flat wire motor is one of the core components of a flat wire motor. The stator is the stationary part of the motor, usually composed of a coil wound with copper wire, and is fixed in the motor housing. Its main function is to generate a magnetic field, drive the rotor to rotate, and complete the operation of the motor.

[0003] The main function of the flat wire motor stator is to generate a magnetic field, which can be a constant DC magnetic field or a variable AC magnetic field. When the current passing through the stator coil changes, the magnetic flux in the conductor will change, which will affect the shape of the magnetic field, and the shape of the magnetic field determines the direction and speed of rotation of the rotor. The magnetic field generated in the stator interacts with the magnetic field in the rotor, causing the rotor to rotate under the action of torque.

[0004] Among flat wire motors, the axial flux motor is a special motor. Its structure and working principle are different from those of the traditional radial flux motor, and the structural difference is also significant.

[0005] The stator core and rotor core of the axial flux motor usually adopt a multi-layer disc structure, and there is a certain gap between them or they are separated by non-magnetic materials.

[0006] The technology of twisting the head of an axial flux motor is still in the research and development stage. The purpose of the present invention is to provide a method for twisting the external pins of an axial flux motor that can be used on a large scale in a factory assembly line.
