As a matter of customers' convenience we offer ready sets of stepmotor and driver or controller - complete stepmotor drives. Stepmotor drives are based on our drivers and controllers and provide excellent performance. The drives differ by motor size and by control unit functionality. We offer drives from tiny 28mm size and 0.4 kgf*cm torque up to 110mm size and 280 kgf*cm torque. We offer simple STEP/DIR controlled drives (based on drivers SMD series) and programmable drives with additional functionality (such as analog speed and position control, home positioning, reverse input and other) based on programmable stepmotor controllers SMSD series.

Programmable stepper drives

Programmable stepmotor drives consist of stepper motor SM series and programmable controller SMSD series. The complete drive functionality depends on a controller model. All drives can be used as simple step/dir drives with pulse position control, as programmable drives with preloaded motion algorithm and as analog speed control drives. All drives except A2832 and A4247 can be used with direct control mode - real-time control by comands from a computer. A110201 has additional analog position control mode. For detailed description, please, refer to a controller model page.

STEP/DIR stepmotor drives

STEP/DIR stepmotor drives consist of stepmotor SM series and stepmotor driver SMD series. The control mode of these drives - usual pulse train mode: STEP/DIR or A-phase - B-phase 90° difference.

Stepmotors with built-in driver

Stepmotor drivers SMD-mini are supplied as one unit with stepper motors. These built-in drivers designed as tiny control devices and built-in to the motor.
