Abstract
A synchronous inductance motor provided in a rotor includes at least a pair of slit portions forming a two-pole magnetic polar projection having an easy-to-pass direction of the magnetic flux, i.e., q-axis and a difficult-to-pass direction of the magnetic flux, i.e, d-axis which are almost orthogonal and a plurality of slot portions close to an outer circumference in the slit portions and connected to at least an end of the slit portion in a direction of the d-axis for generating inductance torque. Further, conductivity material is filled in the slit portions and the slot portions.
