AC Motor Stator And Rotor For Electric Car 

SINGLE SLOT NOTCHING In general production, the effective utilization rate of the punch press does not exceed 30% during manual operation. Once the automatic loading and unloading device is adopted, the utilization rate can be increased to 80~90%. At present, the outer diameter of the largest punching sheet we produce is as high as 1250mm, which is currently the largest width of silicon steel coil. In order to offset the tooth harmonics during the operation of the motor, the slots of the stator core or rotor core are often designed to be skewed, rotary notching is very suitable for the production of this type of motor lamination, which is quite useful for the designs of large size motors.     WORKING PRINCIPLE Usually, there are not too many types of slots on the stator or rotor lamination, and each slot needs a specific tool to stamp. Even so, the overall cost of the tool is very low. The production time of the mold is only one to t…
