The SMC 81RP driver is characterized by its small dimensions, the step division 1/32, the current 1.5 A per phase. A wide range of supply voltages is possible thanks to the pulse converter supplying the controller systems. The controller's work is controlled by a small RISC processor.

The controller is well-suited for servicing small and medium two-phase stepper motors with phase currents up to 1.5 A to ensure smooth drive operation thanks to a deep stepper division. The SMC81RP controller is built into the U-shaped profile.


  • microprocessor, integrated power level for two-phase bipolar motors,
  • chopping with a frequency of 20kHz,
  • power indicators (LED diode),
  • power, signals to the motor and control on the connectors.
