Stepper motors are a subject that keeps recurring. This little circuit changes a clock signal (from a square wave generator) into signals with a 90-degree phase difference, which are required to drive ...

Stepper motors are synchronous motors that step at the pulse rate of the driving signal. For the motor to move quickly, the stepping rate must be fast. However, because of motor and load inertia, the ...

Abstract: A unidirectional and unipolar stepper motor driver has been designed, for the purpose of effectively solving many existed pressing problems in the stepper motor such as high costs, poor ...
