摘要
The rotation of the synchronous reluctance motor is controlled through energization of the winding with current of a phase having a ratio k between the total sum of radial-direction widths of the slits on the q-axis and a magnetic gap length, and having a lead angle β from the d-axis. Among the core layers, the radial-direction width, on the q-axis, of the core layer that lies at a position closest in the circumferential direction to a point P at which there intersect the outer periphery of the rotor and the straight line passing through the rotor center and drawn at an angle ψ=arctan(tan β/(1+0.2k)) from the d-axis, is larger than the radial-direction width of other core layers on the q-axis.
