Abstract
A permanent-magnet stepping motor includes a stator which has resinous protrusions at its one end. An end plate disposed on one side of the stator is molded integrally with the stator. A flange plate is fixed to the other side of the stator, using the protrusions. The stator includes four stator yokes and two annular coils that are disposed at given positions. These yokes and coils are coupled together by molding a resin.
