Single-phase step motor

摘要

A single-phase step motor comprises a stator having a coil, a core and a plate featuring a hole forming poles of the stator, and a rotor having a permanent magnet and a shaft. The rotor is installed in supports. The poles of the stator, which are magnetically asymmetric, are connected by straps. The rotor and the supports thereof are accommodated inside a capsule made as a body and a cover and placed in the hole of the plate. The capsule is provided with an external cylindrical boss coaxial with the rotor, whereas the body of the capsule is provided with a bearing flange which positions the rotor in relation to the poles of the stator.
