Abstract
A synchronous reluctance type rotary electric machine of an embodiment includes a shaft, a rotor core, rotor core pressers, a plurality of conductor bars, and short-circuit rings. The shaft rotates around a rotation axis. The rotor core is fixed to the shaft and includes multi-layered hollow parts having a convex shape toward a radially inward side formed for each pole in cross section. The rotor core pressers hold the rotor core by pressing the rotor core from both sides in a rotation axis direction. The plurality of conductor bars are disposed in the hollow parts to extend along the rotation axis and have both ends protruding through the rotor core pressers. The short-circuit rings are provided at both ends of each of the plurality of conductor bars and connect the plurality of conductor bars together. Thus, the conductor bars are fixed to the rotor core pressers.
