Hexapole motor rotor punching used for injection machine

Abstract

The invention relates to a hexapole motor rotor punching used for injection machines, which is particularly used in hexapole motor rotor core with center height of YZS200 for injection machines. The invention comprises a rotor punching body and an aluminum component. Die-casting is carried on the rotor punching body and the aluminum component to be integral. The invention is characterized in that the rotor punching body is provided with 42 grooves with groove width being 3.7-3.9mm and groove depth being 35-36mm. Matching piece mounted on a fixed rotor punching body of a motor is changed to be 54 / 42, that is to say, the amount of stator punching grooves and the shape of the grooves of the rotor punching body are both constant, only the amount of the grooves of the rotor punching body is reduced to be 42 so as to eliminate electromagnetic noise caused by previous motor in short time under double load in use.

Description

technical field [0001] The invention relates to a rotor punching plate of a six-pole motor for an injection molding machine, in particular to the core of the rotor core of a six-pole motor for a YZS200 high-center injection molding machine. Background technique [0002] With the development and progress of science and technology, people pay more and more attention to the problem of noise pollution in the working environment and living environment. Motor noise has become an increasingly important technical indicator to measure the quality level of motors. Motor noise is generally divided into mechanical noise, ventilation noise and electromagnetic noise. Electromagnetic noise can cause strong and harsh noise feeling, which makes people feel very uncomfortable. The stator punching and rotor punching are the key parts used in the motor, and the stator-rotor slot fit (that is, the number of grooves of the stator punching and the number of grooves of the rotor punching) has a di...

AI Technical Summary

Problems solved by technology

[0003] The motor used on the injection molding machine is required to be used in a double load state in a short period of time. In the prior art, the stator and rotor slots used by the 200-centre-high six-pole motor are 54 / 44 (that is, the stator punch has 54 slots. , the rotor punching sheet has 44 slots), and the motor made of this groove with the stator and rotor punching sheet will generate a certain amount of electromagnetic noise when it is used for a short time at twice the load, which makes people feel very uncomfortable
