Abstract

Provided is a rotor assembly, which comprises a rotor shaft, a rotor core and aluminum rings, wherein the aluminum rings are arranged at both sides of the rotor core respectively. The rotor assembly is characterized in that pluralities of radial de-weighting drill holes are opened on the outer side faces of the aluminum rings, and pluralities of grooves are evenly distributed on the outer surfaces of the aluminum ring. According to the utility model, by carrying out dynamic balance processing on the rotor assembly and carrying out radial de-weighting processing on the aluminum rings, a magnetic circuit of the rotor core can be prevented from damage, the machining precision of dynamic balance of a rotor can be effectively improved, and the vibration and noise of a motor can be reduced.

Description

A kind of rotor assembly

Technical field

The utility model relates to a kind of rotor assembly, particularly a kind of rotor assembly that mainly is applicable to roller washing machine industry usefulness three phase variable frequency motor.

Background technology

Traditional Rotor Assembly dynamic balancing processing mode is to go heavily to process in the iron core end face axial, and this processing mode is owing to go heavily can destroy the magnetic circuit of iron core from iron core, simultaneously owing to go heavy diameter little, the dynamic balancing processing capacity is little, and machining accuracy is poor, causes the vibration of motor, noise large.Therefore, be necessary to be further improved.

The utility model content

The purpose of this utility model aims to provide a kind of machining accuracy height, motor operational shock and the little rotor assembly of noise, to overcome weak point of the prior art.

A kind of rotor assembly by the design of this purpose comprises armature spindle, rotor core and aluminium ring, and the aluminium ring is arranged on the both sides of rotor core, and its architectural feature is that the lateral surface of aluminium ring has several and radially goes heavily to hole.

The outer surface of described aluminium ring is evenly equipped with a plurality of grooves.

The utility model is by to rotor assembly dynamic balancing processing, heavily processes to going from the enterprising conduct of aluminium ring, avoids destroying the magnetic circuit of iron core, but the machining accuracy of Effective Raise rotor dynamic balancing, thus reduce vibration and the noise of motor.
