Stepper Motor Control Trainer, Model: CMC – 101.


  • The Stepper Motor Control Unit houses all the necessary electronic circuits required to operate and control of the Stepper Motor. A control circuit using TTL ICs provides the necessary pulse sequence for continuous rotation in clockwise and anticlockwise directions. In single stepping mode 4 inputs are provided to select 0 and 1 signal through switches. A variable frequency square wave generator with a varying frequency of 10-800 Hz. (approximate) is provided for varying the speed of the motor.
  • All necessary power supply are provided in the same unit. Only 230V ± 10%, 50Hz mains power is required to operate the unit.
  • The motor is, also, housed in the separate cabinet. A 360° calibrated dial is fixed on the shaft of the motor to provide a visual indication of the shaft position.
  • A servo potentiometer is also mounted on the motor shaft, for sensing the shaft position.
  • A microprocessor interface has been incorporated to provide the user with a facility to study the microprocessor control of stepper motor. By using on 8085 microprocessor based kit, the movement of the stepper motor can be programmed to generate any desired profile.


  • This  unit  is  inside  a  metallic  cabinet  with  front  panel  block  diagram. 
  • All  the  necessary  switches,  potentiometer  and  test  points  are  on  the  front  panel.
  • The  features  include  Single  Stepping  and  free  running  mode  of  operation  and  variable  speed  and  direction  reversal – internal  TTL  circuit.
