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 280 center height four-pole motor are 60 / 50 (that is, the stator punching is opened with 60 slots. , the rotor punching sheet has 50 slots), and the motor made of this groove and the stator and rotor punching sheet will generate a certain amount of electromagnetic noise when it is used for a short time under double load, which makes people feel very uncomfortable

Embodiment Construction

[0010] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0011] The present invention only needs to change the stamping die of the rotor punching sheet, and punch out the silicon steel sheet on the punching machine ( figure 1 ) The rotor punching sheet is provided with 52 slots 3 on the rotor punching body 1 . Average groove width: 3.9mm, groove depth: 57.3mm. Then die-cast a certain number of rotor punch bodies 1 and aluminum 2 on a dedicated rotor die-casting machine to form a motor rotor. The proposal of the present invention does not change the original assembly mode of the motor.

Abstract

The invention relates to a four-pole electric machine rotor sheet for an injection molding machine, which is specifically applied in a four-pole electric machine rotor core for the YZS280 injection molding machine with high center. The rotor sheet mainly comprises a rotor sheet body and is characterized in that the rotor sheet body is provided with 52 slots, the width of each slot is 3.8-4.0 mm, and the depth of the slot is 57-58 mm. Because the matching slots arranged on the stator and rotor sheet bodies of the electric machine are changed into 60 / 52, i.e. the number of stator sheet slots remains unchanged and the slot shape of the rotor sheet also remains unchanged, only the number of the slots of the rotor sheet is increased to 52. When the invention is used, electromagnetic noise generated by the original electric machine used at double load in a short time can be eliminated.

Description

technical field [0001] The invention relates to a four-pole motor rotor punching sheet for an injection molding machine, in particular to the iron core of the four-pole motor rotor core for a YZS280 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 direc...
