Why motor stator lamination annealing process are needed for high performance BLDC Motors?
As we know that the silicon steel sheet will cause some internal stresses during punching and stamping process. it is harmful for motor performance and consistency. So a heat treatment process was introduced to eliminate the stresses;
Annealing process is one of heat treatment process that eliminate the microstructure of silicon steel causing changes in properties such as ductility, strength, hardness. For electrical steel laminations of motor stator core, the process of annealing is most commonly used to remove stresses in silicon steel sheet around the edges of a lamination that are induced during punching and stamping process. Another common application in the motor industry pertains to annealing special alloys such as cobalt or nickel to optimize electrical and mechanical properties for special designed high performance motors.
JIAYE can fulfill most annealing requirements for electrical steel laminations. Our expertise in non-grain oriented laminations, grain-oriented laminations, cobalt-based laminations and nickel-based laminations would be benefit for you to get a higher efficiency stators.
There are two types of process for the stator lamination annealing:
