Stator for three-pole external rotor-synchronous motor, has individual windings supported by pole parts, which are fixedly connected with each other, where number of pole parts is equal to number of individual windings

摘要

The stator (10) has a set of pole parts (14) provided in the form of commutator sections and exhibiting a magnetic flux conductive material. The pole parts are arranged on top of each other and are fixedly connected with each other. A set of individual windings (16) is supported by the pole parts, where the number of pole parts is equal to the number of individual windings. Each pole part includes an exterior head section (40) exhibiting an angle extent of preset value. An inner surface of the head section is defined by a plane, which is determined by peripheral ends of the head section.
