3-Phase Step Motor & Drive
3-Phase Stepper System
Stepper Motors are a preferred choice because of their precision of position, control of rotation angle and accuracy of their movement. Steppers, also called as synchronous motor, can be positioned accurately unlike asynchronous motor for example induction motor. Hybrid stepper is a permanent magnet and brushless motor and it combines the principle of a reluctance motor as well. Stepping Motors are 2 phase, 3 phase and 5 phase type and are characterized by the basic movement called step angle or step increment measured in degrees. Two phase motors are usually 1.8 degrees/ 0.9 degrees per step or in other words 200 steps to 400 steps per revolution.
