Rotor, motor, method for manufacturing rotor, and method for manufacturing motor
Abstract:
A rotor includes a rotor core, permanent magnets, and a tubular non-magnetic cover. The permanent magnets are arranged along an outer surface of the rotor core in the circumferential direction. The permanent magnets each include a curved outer surface as viewed in the axial direction. The tubular non-magnetic cover covers the outer surfaces of the permanent magnets. The rotor core includes at least two stacked cores. Each stacked core includes a stack of core sheets. One of the stacked cores is formed from a material having a lower hardness than the other stacked core.
