Title:
SINGLEEPHASE STEP MOTOR
Document Type and Number:
Japanese Patent JPS53100417
Kind Code:
A
Abstract:
A single phase stepping motor, particularly for clocks, with a disclike, axially magnetized rotor with a number of poles and a stator, the latter being made of two stator parts connected with one another via a bridge part, the latter carrying the excitation winding, of which each stator part has on its free end a smaller number (in comparison to the rotor pole number) of main poles with auxiliary poles attached thereon as well as a passage opening for the rotor shaft, the main poles being staggered relative to one another by the same angle, the main poles being directed towards the face sides of the rotor. The main poles and the auxiliary poles which are coordinated to a stator part form an integral unit made of sheet metal with this stator part.
