步进电机-类型、优势及其应用

步进电机-类型、优势及其应用(中文1000字,英文1000字)
步进电机是一种机电设备，它可以将电能转化为机械能。同时它也是一种无刷电动机，可以将一次完整的旋转分开为许多次的步骤。只要电机的尺寸符合应用要求，电机的位置就可以在没有任何反馈机制的情况下实现精确控制。步进电机类似于开关电机。

Stepper Motor – Types, Advantages & Applications
A stepper motor is an electromechanical device it converts electrical power into mechanical power. Also it is a brushless, synchronous electric motor that can divide a full rotation into an expansive number of steps. The motor’s position can be controlled accurately without any feedback mechanism, as long as the motor is carefully sized to the application. Stepper motors are similar to switched reluctance motors.
