What are the differences between a permanent-magnet stepper motor and a variable reluctance stepper motor?
What will be an ideal response?
A permanent magnet stepper motor using permanent magnets on the rotor and moves to align itself with unlike poles on the stator when current activates one of the stator magnets. A variable-reluctance stepper motor has a toothed rotor constructed from a magnetic material. As stator magnets are activated, the rotor moves to align its teeth with the magnetic field of the stator.
