<p>A brushless DC motor includes armature windings mounted on the motor stator, magnetic poles mounted on the motor rotor, a plurality of commutating devices and one or more rotor position sensors or detectors. Each pair of the upper and the lower arms of the commutating devices comprises one half I-bridge switch. All such half H-bridge switches connect the DC bus and respective junction points between adjacent two armature windings. A commutation method of brushless DC motor and a control iethod of brushless DC motor are also provided.</p> |
