AC motors vary from a lot of other types of motors, especially some of the much more familiar DC (immediate recent) motors, by several essential requirements. The most basic of these is the truth that an AC motor depends entirely on the alternating current around its circuit to generate effective mechanical energy. We’ll examine this distinctive approach in more depth in the pursuing sections of this manual.
The rotor of a reluctance motor is composed of a solid cast steel part with a convex toothed rack. Their commencing approach is comparable to an induction motor, but it operates like a synchronous motor. Typically, their rotors have fewer poles than stators, which minimizes torque ripple and stops perfect pole alignment, as no torque is made in that area. Reluctance motors range in power scores from a few watts to about 22 kilowatts.
