Title: Reluctance motor
Inventor: MAKITA SHINJI
IPC: H02K1/14
Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To suppress cost increase caused by forming slits in the salient poles of stacked plates as low possible. SOLUTION: In order to form slits 3 at a low coat, the slits 3 are formed by press machining using a die instead of laser machining. The thickness of a stacked plate 1 is not larger than 5 times of the maximum width of the slit 3 to extend a die life. With this constitution, the cost for the die can be reduced and the manufacturing cost of the stacked plates 1 in which the slits 3 are formed can be suppressed. When the stacked plates 1 are subjected to press machining, the slits 3 are formed simultaneously, so that the increase in the number of processes for forming the slits 3 can be eliminated and the increase of the cost can be suppressed.
