| Zusammenfassung: | A motor (1) includes a case (10), a conductive shaft (18), a bearing (20, 25), a rotor core (30), a coil (15), and an electrostatic shield (40, 45). The rotor core (30) has a ring groove (31a, 31b). The rotor core (30) includes a first core portion (33), a second core portion (34), and a third core portion (35). At least one of the first core portion (33), the second core portion (34), or the third core portion (35) is formed of an insulative material. The electrostatic shield (40, 45) is disposed between the coil (15) and the conductive shaft (18) and electrically connected to the conductive case portion. A part of the electrostatic shield (40, 45) is within the ring groove (31a, 31b). |
