Design and Development of Rectangular Type High Torque Hybrid Step Motor

사각 고토오크 하이브리드 스텝모터의 설계 및 개발

Rectangular type hybrid step motor is designed to generate thirty percents higher torque than existing step motors. The torque for the motor is generated by the electromagnetic force at the air gap between the stator and rotor. The generating torque is proportioned to the rotor volume, i. e. rotor diameter. The main idea in this study is that the diameter of rotor is increased to generate more torque for the same overall motor size. This motors are manufactured by varying the shape of the teeth width of the stator and rotor. The optimum shape of the teeth is selected from the standpoint as smaller step angular accuracy.
