Motor rotor stampings for motors and generaotors

SINGLE SLOT NOTCHING

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.

Single Notching is one of our best strengths, it's a good and economical choice for medium & large size Motor Lamination production. 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 special good quality laminations.

APPLICATION & COST

If the number of pole pairs of the rotor magnetic field is equal to that of the stator magnetic field, the rotor magnetic field rotates synchronously with the stator rotating magnetic field due to the magnetic pull of the stator magnetic field, and the rotor rotates at the same speed and direction as the rotating magnetic field.
