ABSTRACT:
In a multi-phase bipolar brushless D.C. motor in which the permanent magnet instead of the field coil is used for the rotor, the armature is used for the stator. The winding is wound on the stator as the independent phase-connected winding, the commutation encoder is fixedly mounted on the shaft of the rotor to be rotated, and the photo-sensor is coupled operatively thereto to be connected with the driving circuit, thereby the motor is smoothly started and rotated with a simple construction, and is manufactured at low cost.
