More Information
Summary:A magnetic core of an electric motor includes a central portion and a plurality of teeth extending outwardly from the central portion, the teeth disposed along a circumferential direction of the central portion. Each tooth includes a tooth body, two neck portions and two crown portions, the neck portions respectively connecting the crown portions to the tooth body, the two crown portions respectively extending beyond opposite sides of the tooth body. Each of the two neck portions of each tooth has a minimum width which is 0.1˜0.3 times of the width of the tooth body. The present invention further provides an electric motor that employs the magnetic core which can increase the peak value of the cogging torque of the motor.
