Description
Technical Field
The invention relates to a motor assembly process, in particular to an axial flux motor, and particularly relates to assembly of a double-rotor axial flux motor.
Background
The axial flux motor is flat in structure and short in axial dimension, so that the axial flux motor is particularly suitable for application occasions with limited axial dimension, such as an electric automobile hub motor, an elevator lifting traction machine, a mute submarine propulsion motor and the like. Since the axial flux machine structure is different from the radial flux machine structure, there is a large difference in the assembly of the two. The assembly scheme of a conventional radial flux machine is not applicable to an axial flux machine. When the axial flux motor is assembled, as the axial magnetic tension generated by the permanent magnet is large, the installation precision of the axial flux motor can be ensured by means of various fixed platform devices; and the installation of the bearing usually adopts interference fit, and the inner ring and the outer ring of the bearing are respectively clamped on the stator fixed shaft and the rotor, so that the installation complexity and the difficulty are greatly increased when the two parts are assembled and installed, and the axial flux motor with a double-rotor structure is particularly improved. In addition, the output performance of the double-rotor motor can be greatly different due to different double-rotor angle differences and air gap thicknesses, the relative positions of the double rotors and the air gap thicknesses of the motor are usually in an unadjustable state after the traditional assembly process is completed, and the output performance of the motor cannot be correspondingly adjusted according to actual requirements.
In summary, the assembling process of the dual-rotor axial flux motor provided by the invention can realize flexible adjustment of the thickness of an air gap, synchronous rotation of the dual rotors in the same position and dislocation, and synchronous rotation, and provides a simpler process, so that accurate positioning and installation of the rotor can be realized without an additional assembling platform.
