    Mar 18 2020 · Stator will be placed as close as possible to rotor so that magnetic fields in stators can influence rotor s movement. To control the stepper motor each stator will be powered one by one alternatively. In this case the stator will magnetize and act as an electromagnetic pole exerting repulsive force on the rotor and pushes it to move one step.
