2-Phase Stepper Motors
A two-phase stepper motor develops controlled rotary movement by changing the excitation of two electrical winding phases in sequence. In a common hybrid construction, toothed stator poles interact with a permanent-magnet rotor so successive current states shift the rotor's equilibrium angle. The driver determines the excitation sequence and current; the load determines whether the rotor can follow it.
