DC Source
The DC Source is useful for assessing the operation of Unipolar and Bipolar Stepper Motors of different specifications. The DC Source has an internal power supply and a driver and control circuit to drive Unipolar and Bipolar Stepper Motors of all specifications. The operator can set the values for operating voltage, operating mode, phase excitation, PPS, direction of rotation depending on the specification of the motor.


Controlled Parameters

  • Operating Voltage (0-60VDC, 3A)
  • PPS (5 – 5000 PPS)
  • Direction of Rotation (CW/CCW)
  • Operating Mode (Full Step/Half Step/Wave Drive)


  • Allows simple manually controlled driving of all types of Unipolar and Bipolar Stepper Motors using an in-built DC power source
  • Electrical connections are made using quick connect arrangement
  • Unipolar and Bipolar Stepper Motors are driven using the same DC Source
  • Provision for connecting an external power supply
  • Provision for connecting an oscilloscope to monitor PPS
  • Individual displays for displaying the values of set operating voltage and PPS
  • Easy to maintain compact bench top construction
