Abstract
The present invention relates to a brushless direct-current motor, which comprises two stators arranged along the same axis. Each stator has a ring-shaped body. The body is provided with stator teeth extending towards the body center. A boot portion is formed at a tail end of each stator tooth. Each stator tooth is wound with coil having a predetermined number of turns. The boot portions of two stators are staggered mutually and wound with each other to form a circular hole shape. A plurality of permanent magnets are circumferentially arranged at a rotating shaft of the rotator, wherein all permanent magnets are arranged in an S/N pole staggered configuration manner at the periphery of the rotating shaft. Therefore, when the coil circuits of the two stators are driven alternatively or a coil circuit of any stator is driven, the rotator is continuously rotated toward the same direct, so as to not only reduce limitation of the power supply used by the brushless direct-current motor but also relatively save the electric energy when rotating the brushless direct-current motor in a full-time mode, thereby reducing the generation of cogging torque and realizing the noise reduction effect.
