Beschreibung
Zusammenfassung:A rotor 10 of an electric motor configured by combining a resin magnet section 5 molded of thermoplastic resin 3 containing ferrite and a rotation shaft 6 includes a magnetic section 1 for position detection integrally formed of the thermoplastic resin 3 on an end face 5a on one side of the resin magnet section 5, the thermoplastic resin 3 being injected from an inner diameter side of the resin magnet section 5 to the end face 5a. Because the position of the rotor 10 can be detected by the magnetic section 1 without using a magnet for position detection, cost reduction can be achieved while the accuracy of detecting the position of the rotor 10 is ensured.
