 Bipolar Stepper Motor (Current Calculator)

A stepper motor (or step motor) is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application.

This calculator has been developed considering the IC L297 and L298.
