Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0039] It should be noted that if there are directional indications involved in the embodiment of the present invention, the directional indications are only used to explain the relative positional relationship, movement conditions, etc. between the components in a specific posture. If the specific posture changes , then the directional indication changes accordingly.

[0040] In addition, if there are descriptions involving "first", "second" and so o...

Abstract

The invention provides a rotor assembly for a disc motor and the disc motor. The rotor assembly for the disc motor comprises a rotor support disc, an annular hoop and a positioning pin, the rotor support disc is in a circular shape with a central opening, a boss is disposed on the outer circumferential surface of the rotor support disc, the annular hoop sleeves the rotor support disc, the inner circumferential surface of the annular hoop is provided with a clamping slot matched with the boss, and the positioning pin connects the rotor support disc with the annular hoop and used for limiting relative rotation between the rotor support disc and the annular hoop. The mode of sleeving the rotor support disc with the annular hoop is adopted, not only is the effect of enhancing the structural strength of a centrifugal force during high-speed rotation achieved, but also automatic weight reduction of an automatic dynamic balancing machine can be supported, the automatic production is met, andthe cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a rotor assembly of a disc motor and the disc motor. Background technique [0002] The disc motor has a high torque density and has broad application prospects. The rotor assembly of the disc motor generally includes a rotor support disc and a permanent magnet. The rotor support disc is used to install and fix the permanent magnet. In the prior art, the rotor support plate is generally made of aluminum alloy. The rotor support plate not only provides support strength, but also plays a magnetic isolation role. However, the density of the aluminum alloy material is too small to meet the G1.5 grade requirements of high-precision dynamic balance. Weight gain is needed, but the existing way of weight gain cannot realize automatic continuous production. Contents of the invention [0003] The main purpose of the present invention is to provide a rotor assembly of a disc motor and a di...
