Abstract

A bipolar stepping motor includes, a single stator sheet, an air gap between the ends of the stator sheet, a rotor between the ends of the stator sheet, and a coil which encompasses a portion of the stator sheet. The stator sheet is of essentially annular configuration and is surrounded over a substantial portion of its periphery by a coil carrier. The coil is applied on the carrier in the form of a ring core winding. A carrier plate is attached to the stator sheet in the vicinity of the air gap. This plate carries a shaft of the rotor and serves as means for attaching the motor to another structure.
