Stepper Motor Controller Circuit

Working Explanation

There are two stages of the 555 Timer Stepper Motor. In the first stage, there is a timer IC that is working as an astable multivibrator and generates a square pulse depending on the values of the timing resistor and timing capacitor. In the second stage, there is a decade counter Integrated circuit CD4017. This counts the square pulses that are coming from the timer IC and gives stepping pulse output through four transistors output pins that are wired in the circuit. We provide all pulses to the coil of the stepper motor through switching transistors.

Application and Uses

  • We use it textile machines
  • We can use it in the 3D printing device
  • It can exist in gaming devices
  • We widely used it in Robots
  • CNC machines also operate with the stepper motor
