Abstract
The invention belongs to the technical field of motor stators, and particularly relates to a permanent-magnet brushless direct-current motor stator with novel parallel winding wiring. The permanent-magnet brushless direct-current motor stator with novel parallel winding wiring comprises a stator iron core and stator windings. Each phase winding is composed of two sections of windings. The two sections of windings of each phase winding are coiled along stator grooves in the stator iron core. The two sections of windings of each phase winding are connected in parallel, so that a phase wire common end and a phase wire input end are formed respectively. The permanent-magnet brushless direct-current motor stator with novel parallel winding wiring can be used on the condition of any power level of a permanent-magnet brushless direct-current motor, and is high in efficiency, small in phase current, and capable of greatly reducing the possibility of demagnetization, caused by temperature rising, of a permanent magnet, reducing cost, reducing the magnetic energy loss, and effectively avoiding the phenomena that due to the fact that the current is too large, the permanent magnet is demagnetized and a machine breaks down.
