Armature plate and synchronous motor suitable for plate type coreless permanent magnet synchronous motor

Abstract

The invention relates to an armature plate and a synchronous motor suitable for a plate type coreless permanent magnet synchronous motor. The armature plate is provided with an armature. The armature is provided with an armature body and a coil winding. The coil winding is installed in an inner round of the armature body. The coil winding is composed of multiple winding coils. Each winding coil is formed by winding enamel covered sheet wires in a single row mode. The multiple winding coils are wound and arranged to be a round structure in a single layer mode without overlapping. The winding coils and the armature plate body are pressed and then form an annular body with a hole at the center. The armature of the synchronous motor is clamped between a left half shell body and a right half shell body which are installed oppositely. With the armature plate and the synchronous motor suitable for the plate type coreless permanent magnet synchronous motor, the tough situation that when an exiting plate type coreless permanent magnet synchronous motor is manufactured, multiple rows and multiple layers of windings are required is avoided. The armature plate and the synchronous motor suitable for the plate type coreless permanent magnet synchronous motor have the advantages of being simple in winding manner and manufacture technology, high in production efficiency and low in rejection rate. Meanwhile, the motor with the armature plates is light in weight and stable in rotation speed and yield is improved.

However, it is difficult to process and manufacture the armature windings of the existing disc-type coreless permanent magnet synchronous motors. The armature windings are made of multi-layer and multi-row windings of enameled wires. During the manufacturing process, high-precision winding machines and special cards are required. The production process is complex and the production efficiency is low, which limits the mass production of the motor at low cost. At the same time, in the disc permanent magnet synchronous motor, it is difficult to obtain an ideal sinusoidal distribution of the magnetic field in the air gap space of the motor
