Unipolar Stepper Motor

A unipolar stepper motor is a special stepper motor, which is characterized by achieving stepping motion through a specific driving mode. This motor usually has a permanent magnet with 5 or 6 wires and a hybrid structure. Its working principle is based on a design in which each of the two windings has a central tap. In use, the center tap of the winding is usually connected to the positive power supply, and the two ends of each winding are alternately grounded to reverse the direction of the field provided by the winding. This design enables the unipolar stepper motor to achieve stepping motion in a simple and effective way.
