Abstract:
The present invention is to provide a rotor capable of further increasing curvature of a permanent magnet while absorbing strain in the permanent magnet.A rotor having an embedded magnet type structure includes a rotor core having a plurality of slots disposed in a circumferential direction and a plurality of magnet parts respectively stored in the plurality of slots. Each of the plurality of magnet parts includes a pair of first sintered magnets each of which has a bar shape in a sectional view cut along a plane orthogonal to a rotary shaft and each of which is disposed so as to come closer to the other first sintered magnet along a radially inward direction of the rotor core, a second sintered magnet which has a curved shape curved in an arc shape in the sectional view and each of both end surfaces of which faces each of end surfaces in the radially inward direction of the pair of first sintered magnets, and a connecting member which is formed of resin and which connects each of the pair of first sintered magnets and the second sintered magnet.
