STEPPER MOTOR DRIVERS

stepper motor driver

We offer the stepper motor drivers for full line of motors - from tiny stepper motors 20 mm flange size up to high torque stepper motors 110 mm size. For space economy projects we offer tiny drivers, whish are built-in to stepper motors - SMD mini series. For 2 and 3-axes applications we offer drivers for 3 motors - SMD-303. Standard versions of our stepper motor drivers SMD series are widly used in CNC machines, robotics, process automation systems and others.

SMD series drivers are suitable to control bipolar 2 and 4-phase stepper motors. Microstepping mode provide smooth and exact positioning. Enable input can be used as alarm input or sudden stop. During position holding motor current can be reduced in order to make lower heating and energy save, this function can be switched on or off by customer.

SMD drivers process STEP (Pulse) and DIR (Level) signals as motion reference. High level voltage is 5 ‑ 24 VDC which is suitable for the most signal sources. Such sources could be PLC, PC or any frequency generator.
