STEPMOTOR DRIVERS

stepmotor driver

We offer the stepmotor drivers for full line of stepmotors - from tiny stepmotors 20mm size up to high torque stepmotors 110mm size. For space economy projects we offer tiny stepmotor drivers, whish are built-in to stepmotors - SMD mini series. For 2 and 3-axes applications we offer stepmotor driver for 3 motors - SMD-303. Standard versions of our stepmotor 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 5-24VDC which is suitable for the most signal sources. Such sourcrs for these stepmotor drivers could be PLC, PC or any frequency generator.
