Abstract
An improved method for stator of a motor, which is related to a shape of a stator made of laminated silicon steel in a motor; the prime of the method is to reduce the cogging torque upon the motor running so as to reduce the vibration of motor, and to increase the performance of the motor as well; the result of such method can be used for a stator made of laminated silicon steel in a motor so as to improve the structure of a stator in conventional motor, which used to generate a cogging torque.
