Abstract:
A rotor includes a rotor core formed of a stacked body in which two or more first electromagnetic steel sheets and a second electromagnetic steel sheet are stacked in a direction of an axis, the rotor core having a magnet insertion hole passing through the stacked body in the direction of the axis, and a first permanent magnet and a second permanent magnet disposed in the magnet insertion hole. The magnet insertion hole has a first region in which the first permanent magnet is inserted, and a second region in which the second permanent magnet is inserted. Each of the two or more first electromagnetic steel sheets has a bridge dividing the magnet insertion hole into the first region and the second region. The second electromagnetic steel sheet has the magnet insertion hole in which the first region and the second region are formed continuously with each other.
