Stator lamination for large drive motor

SINGLE SLOT NOTCHING

Single Notching is one of our main competencies, it's quite a good and economical choice for medium & large size Motor Lamination production.

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

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.

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. The stator part converts electrical energy into magnetic energy , the stator magnetic field pulls the rotor magnetic field to form the mechanical operation of the rotor, and realizes the conversion from electrical energy to mechanical energy.

APPLICATION & COST

The production time of the mold of the slots on the stator or Rotor Lamination is only one to two days, each slot needs a specific tool to stamp, but the good thing is  the overall costs are quite low. 

Single notching 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. Most of our CNC presses are equipped with automated production systems. These devices can greatly reduce production costs while ensuring production speed.
