Abstract
A stator (1) includes a core member (10) having a central portion (12) with an even number of pole members (14–17) extending radially and outwardly from the central portion, a winding having a same even number of winding portions (20a–d) wound around the pole members respectively, and a drive circuit (50) having the winding connected thereto. A half of the winding portions is arranged in parallel with the other half of the winding portions. During working, the electric current passes the whole winding in alternate direction to establish alternate magnetic fields to drive a rotor of the motor to run.
