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.

步进电机是一种广泛用于不同领域的执行器，用于机器人和数控机床等各种用途。这种电机有 3 种不同的类型，混合型是最常见和最有用的一种。本文提出了一种传统混合式步进电机 (HSM) 的新结构，与传统电机相比，该结构大大提高了扭矩密度，并且提高了 200% 以上。该电机首先在计算机上建模，并使用 3D 有限元法 (3D FEM) 软件进行分析。然后将结果与传统电机进行了比较，证明其优越性后，制作了它，并比较了理论和实际测试的结果。这些结果证实了 HSM 新结构的优势。
