A rotary portion 2 of a synchronous induction motor 1 includes an annular rotor core 31, a secondary conductor 32 and a plurality of permanent magnets 33. The secondary conductor 32 includes a plurality of conductor bars 60 which are provided in secondary conductor slots 311 in the rotor core 31; and a pair of end rings 61, 61 which connect each end of the plurality of conductor bars 60 into an annular shape. The plurality of permanent magnets 33 are respectively provided in magnet slots 312 provided in the rotor core 31. Further, the plurality of permanent magnets 33 are provided such that same pole of the neighboring permanent magnets 33 face each other in a circumferential direction. A magnetic flux of the permanent magnets 33 flows from the permanent magnets 33 toward the circumferential direction, but not the radial direction.
