BRUSHLESS DC MOTOR CAPABLE OF IMPROVING THE MAGNETOMOTIVE FORCE INTO A SINUSOIDAL WAVE

摘要

PURPOSE: A brushless DC motor is provided to improve the efficiency and performance of a motor by enhancing the sine nature of magnetomotive force.;CONSTITUTION: In a brushless DC motor, a teeth(104) are protruded from the inside of a base(102) in radial direction. A stator core(100) comprises a pole shoe(106) which is extended from the end of the teeth to both sides. A rotor forms a plurality of magnets and a plurality of concave parts in outside. The opposite of the rotor in the pole shoe has a liner part and a projection which is protruded from the linear part to the rotor.;COPYRIGHT KIPO 2012
