Disc rotor and disc motor

Abstract

The invention discloses a disc rotor and a disc motor. The disc rotor comprises a ring iron core which is provided with multiple sets of magnetic steel installing positions, wherein the magnetic steelinstalling positions are provided with buckle devices; magnetic steel which is installed in the magnetic steel installing positions and can be buckled in the magnetic steel installing positions by the buckle devices; a ring hoop which sleeves the outer circle of the ring iron core and is connected with the outer circumferential surface in an abutting way; and a rotor support which is provided with a ring boss which is inwardly sleeved in the inner circle of the ring iron core and connected with the inner circumferential surface in an abutting way, wherein the ring iron core is connected withthe rotor support through first screws. The ring iron core is fixed on the rotor support through the first screws and the rotor support axially limits the ring iron core so as to prevent axial displacement under the axial tension of the stator iron core. Besides, the buckle devices are arranged in the magnetic steel installing positions and the buckle devices can buckle the magnetic steel in the magnetic steel installing positions so as to prevent axial displacement of the magnetic steel.

Description

technical field [0001] The invention relates to the technical field of motor components, in particular to a disc rotor and a disc motor. Background technique [0002] Radial field motors and axial field motors (also called disc motors) are two major branches of the motor field. Disk motors are more and more widely used because of their higher iron core utilization, higher power density and higher torque density. [0003] At present, the rotor assembly of a disc motor is mainly composed of a rotating self-supporting disc 8, an annular iron core 1, a permanent magnet 9 and a fixed ring 10, such as figure 1 shown. The permanent magnet 9 is installed in the steel groove of the annular iron core 1 , and the support disc 8 and the fixed ring 10 are respectively installed on the inner and outer sides of the annular iron core 1 to limit the radial direction of the permanent magnet 9 . [0004] However, in actual use, the permanent magnet 9 and the ring core 1 will be subjected to...

AI Technical Summary

Problems solved by technology

[0004] However, in actual use, the permanent magnet 9 and the ring-shaped iron core 1 will be subjected to a huge axial magnetic pulling force from the stator core, making it difficult for the rotor assembly to fix the ring 10-shaped iron core 1 and the permanent magnet 9 in the axial direction
