Stepper motors require some external electrical components in order to run. These components typically include a power supply, logic sequencer, switching components and a clock pulse source to determine the step rate. Many commercially available drives have integrated these components into a complete package. Some basic drive units have only the final power stage without the controller electronics to generate the proper step sequencing.

Products & Services
Stepper motor drives power unipolar and bipolar stepper motors in full step, half step, and microstep motion control applications.
DC motor drives act as the interface and power supply between a motion controller and a DC motor.
DC motors are most commonly used in variable speed and torque applications. They include brushless and gear motors, as well as servomotors.
IC drivers or gate drivers provide the current and voltage necessary to turn power switching elements such as MOSFETs or IGBTs either on or off, based on the logic output signals of a DSP, micro-controller or other logic device.
Motor controllers receive supply voltages and provide signals to motor drives that are interfaced to motors. They include a power supply, amplifier, user interface, and position control circuitry.
