Motor Rotor/Motor Lamination/ Silicon Steel Core/

SINGLE SLOT NOTCHING

Some cold-rolled electrical steel sheets with inorganic and organic coatings can increase the number of times of die sharpening by nearly ten times.

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.

APPLICATION & COST

Some motors often have higher requirements for magnetically conductive materials, such as small magnetic failure, small magnetostriction and so on. 

We can guarantee the production speed while reducing the production cost, since more than half of our CNC presses are equipped with automated production systems. Single notching is very suitable for low-to-medium volume production or prototype development, the tool cost of it is quite low.
