Motor Core Stamping

Sectioned Stators

It is possible to save material cost and increase productivity by changing parts configuration.

Cost reduction alternatives

With dual stamping technology single press is needed whereas conventional stamping use 2 presses for each rotor and stator. Productivity will double by DST.

Improve productivity

Advantages of DST

At Mitsui, Dual Stamping Technology makes it possible to produce the rotor and stator from the same material saving the inside portion (shown in red) that had usually been thrown away. The blue spots of stator in the figure above are coined and streched to create the ideal gap. It may sounds simple but require precision techniques.

One of the crucial elements for performance of stepping motor is the gap (clearance) between stator and rotor. To improve the performance the gap between stator and rotor must be carefully narrowed. Ordinarily two separate materials are prepared for each rotor and stator and rotor is stamped larger than the diameter of the inside of stator (in red) and ground to create an ideal gap in between.
