Slot wedge, stator and motor, and method for manufacturing slot wedge

Abstract

The invention provides a slot wedge, a stator and a motor, and a method for manufacturing the slot wedge. The slot wedge for a stator core of the motor comprises a laminated body formed by laminatinga plurality of magnetic conductive sheets, and the laminated body is strip-shaped, wherein the slot wedge is provided with a plurality of ventilating slots; and the ventilating slots are formed by penetrating through the laminated body along the radial direction of the stator core. The slot wedge for the stator core of the motor provided by the invention can effectively reduce harmonic waves and improve the air gap flux distribution, so as to improve the working efficiency and rated power of the motor; and at the same time, the heating of the motor can be reduced and the service life of the motor can be prolonged.

AI Technical Summary

Benefits of technology

This patented technology describes how different parts on one part of a rotating machine (the stator) have specific positional relationships between them called “ventilations” which help prevent excessively high temperatures from affecting certain components like motors. By combining multiple layers of magnets into this space, these spaces allow some coolant gases to circulate around the machines while keeping their internal structure intact without getting too hot during operation. Additionally, there may exist other ways to attach the electrical leads within the machine itself instead of just fitting them inside. Overall, this design allows for efficient use of energy and reduces thermal stress levels over longer periods of usage compared to traditional methods such as adding insulation material.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving the efficiency and durability of electric machines with rotating blades made from materials like steel wire rods. Current methods involve adding insulation between different parts of the machine's coils (stators) which reduces heat generation but also increases power consumption due to increased resistance caused by airflow through these gaps. There has been some research on developing better ways to improve cooling systems without increasing weight or cost while maintaining good electrical conductivity.
