Electric Motor Stator Lamination With Reasonable Price

SINGLE SLOT NOTCHING

Almost all of the manufacturers want to pursue a good and economical choice, coincidently, we are very skilled in the craft of Single Notching, which is especially suitable for medium & large size Motor Lamination production.

At this time,  the largest width of silicon steel coil and the outer diameter of the largest punching sheet we produce is 1250mm. If we want to offset the tooth harmonics during the operation of the motor, the slots of the Stator Core or Rotor Core are often need designed to be skewed, rotary notching is a nice choice for the production of this type of motor lamination, which is a good match for the designs of large size motors.    

WORKING PRINCIPLE

Each slot which is on the stator or Rotor Laminationneeds a specific tool to stamp,  but usually there are not too many types of slots on the stator or rotor lamination. Even so, the overall cost of the tool is very low. The production time of the mold is only one to two days.

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.

APPLICATION & COST

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

Manufacturing automation mainly refers to automatic loading and unloading, automatic punching and automatic sorting of workpieces into stacks, it not only can ensures safe production, but also can satisfactorily solve the contradiction between safety and production.
