Stepper motors are widely used in holding and positioning applications in the computer, security, industrial automation and automotive sectors. Depending on the number of phases, the winding arrangement and the required level of motion smoothness, ST offers several types of bipolar stepper motor drivers to ensure the best performance for your application.

Bipolar Stepper Motor
Bipolar Stepper Motor
In bipolar stepper motors, current can flow in both directions; a full-bridge converter is required to drive each of the two windings of a two-phase motor...
