The project utilizes scavenged stepper motors from disk drives or printers with some probing of an ohmmeter followed by some simple driver code on the microprocessor. The project utilizes scavenged ...

The project illustrates the control of two unipolar stepper motors using this circuit in full step mode through the RS232 serial port of the PC. The signals from the serial port of the PC is being ...

Find a downloadable version of this story in pdf format at the end of the story. A new controller IC, the L6470 for stepper motors, integrates the power stage along with a digital control core on a ...

Today's smart power ICs drive a wide range of small motors such as dc, stepper and brushless dc (BLDC). These smart power ICs typically interface directly Thomas Hopkins, Director, Power Systems ...
