Four phase drive signals for two phase bipolar and four phase unipolar step motors in microcomputer-controlled application is easily implemented using L29 Stepper Motor Controller IC. We can drive the motor in half step, normal and wave drives mode and switch-mode control of the current in the windings is permuted on chip PWM chopper circuits. This device has some features […]
