<p>Shapes of a rotor (10) and a stator (12), and periods and phases of currents of each of the phases are so determined that a variable reluctance motor will rotate as smoothly as an AC servo motor. When the number of phases is denoted by m, the number of salient poles (Rj) of the rotor is denoted by n, and the number of salient poles (Sk) of the stator is denoted by r.m, then n is an integer times r. When the stator salient pole (Sk) has a rectangular shape, the rotor salient pole (Rj) has the shape of a sinusoidal shape, each of the phases has a period twice as long as that of a magnetic permeance change that accompanies the turn of the rotor, and an AC sinusoidal wave current is supplied being deviated by 2npi/(r.m) for each of the phases. @(20pp Dwg.No.1/6)@.</p> |
