Stator And Rotor Laminations For Induction Motors

SINGLE SLOT NOTCHING

The higher the magnetic permeability, the smaller the cross-sectional area of the magnetic circuit, the saving of the amount of copper used in the excitation winding, and the reduction of the motor volume under the condition of constant magnetic flux.

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

In the process of Single Notching, the tool only cuts one slot on the round sheet at one time, which means that the total number of cuts is equal to the number of slots on the lamination. All of our CNC single notching press have a high precision positioning system and indexer, which can control every action of the machine and allows us to produce some very special laminations.

More than half of our CNC presses are equipped with automated production systems. These devices can greatly reduce production costs while ensuring production speed.

APPLICATION & COST

Single notching is one of our main competencies. It's quite a good and economical choice for medium & large size motor lamination production and is very suitable for low-to-medium volume production or prototype development, the tool cost of it is quite low. Its production speed is relatively slow, and the time to produce a lamination varies from a few seconds to tens of seconds.
