Title: Motor with simplified structure and related control device

Abstract: A brushless motor and a related control device are disclosed in a structure wherein a stator has U-phase, V-phase and W-phase stator poles, with two of the U-phase V-phase and W-phase stator poles carry thereon respective phase windings, in the absence of a selected phase winding related to a remaining one of the U-phase V-phase and W-phase stator poles. The respective phase windings have end portions connected together at a junction point. A three-phase alternating voltage is applied to the respective phase windings and the junction point to allow the stator to have an electromagnetic action thereby drivably rotating a rotor. The stator poles may be formed in trapezoid shapes to minimize interference between associated component parts for easy assembly in high productivity and efficiency with a reduction in torque ripple.
