Title:
STATOR OF HYBRID TYPE STEPPING MOTOR
Document Type and Number:
Japanese Patent JPS60261353
Kind Code:
A
Abstract:
PURPOSE:To improve the inserting work of a coil frame by alternately varying the length of a salient pole of an approaching stator. CONSTITUTION:A stator 1 of a hybrid type stepping motor used for driving a head of a floppy disk has salient poles 2, 3, and a coil frame 4 wound with exciting coils is inserted fixedly into the stator. In this case, the poles 2, 3 have different lengths between the adjacent salient poles, for example, in such a manner that the length l1 of the pole 2 is shorter than that l2 of the pole 3. The lengths l1, l2 are lengths from the ends 6 to the base 8 of the poles 2, 3.
