Abstract

A method of manufacturing a rotor for a motor and a rotor for a motor manufactured by the same are disclosed. The method includes providing a rotor plate, a rotor core, and a plurality of permanent magnets, integrally coupling the rotor core to the rotor plate. The method also includes forming a molding part by molding a resin composition for a molding material on the plurality of permanent magnets so that the molding part is shaped to integrally connect the plurality of permanent magnets arranged in a circumferential direction of the rotor. The rotor is manufactured to have a configuration in which the rotor plate, the rotor core, the plurality of permanent magnets, and the formed molding part are integrated.
