Abstract

A stepper motor is an actuator widely used in different areas for various purposes such as robots and CNC machines. This motor has 3 different types and the hybrid type is the most common and useful one. This paper has presented a new structure for conventional hybrid stepper motors (HSMs) that has improved the torque density dramatically and more than 200% compared with the conventional ones. This motor firstly is modeled on the computer and has been analyzed with a 3D finite element method (3D FEM) software. Then the results have been compared with the conventional motors and after the proof of its superiority, it is fabricated and the results of theoretical and practical tests are compared. These results confirm the advantages of the new structure for HSMs.
