The rotor of a reluctance motor is composed of a reliable forged metal component with a convex toothed rack. Their beginning procedure is related to an induction motor, but it operates like a synchronous motor. Normally, their rotors have much less poles than stators, which minimizes torque ripple and stops best pole alignment, as no torque is made in that area. Reluctance motors range in energy scores from a number of watts to about 22 kilowatts.
