Background

The disc type motor is an axial magnetic field motor, and the air gap between the stator and the rotor is in a plane shape, so that the disc type motor is obviously different from a circular air gap of a traditional radial motor.

At present, the combination of the disc type motor is mainly completed manually, the assembly of the stator or the rotor on one side can be completed only firstly, and the stator or the rotor on the other side can be assembled only after the axial positions of the stator and the rotor are kept unchanged. Therefore, a special tool needs to be designed to axially lock the stator and the rotor so as to prevent the stator and the rotor from generating axial relative displacement under the action of axial suction force, so that the uniformity of an air gap is influenced, and the problems of multiple operation steps, low assembly efficiency and the like caused by the fact that the motor is flanged for multiple times in the assembling process of the stator and the rotor are solved.

However, this form of multiple unit apparatus suffers from significant drawbacks and problems: adopt the form that horizontal axial attaches together to attach together when rotor fixing base 1 'installation and fixed rotor 2', not only occupied rotor 2 ''s axial space, lead to unable attaching together, moreover, because horizontal axial installation, the central line that stator 5 ', rotor 2' and back stator 6 'before can't guaranteeing is unanimous, attaches together the precision low, appears the quality problem easily. In addition, because the two plane air gaps between the front stator 5 ', the rotor 2' and the rear stator 6 'in the assembly are 1mm to 2mm, the rotor can not be taken out from the rotor fixing seat 1' after the assembly is completed. The whole assembling process has complicated working steps and low assembling efficiency.
