| 摘要 |
The present invention is an electric motor capable of preventing or reducing galvanic corrosion of a bearing. A conductive shaft (30) extends along an axial direction. Bearings (41, 42) each include a conductive inner ring (411, 421) and a conductive outer ring (412, 422). The inner ring (411, 421) is fixed to the shaft (30) while being in contact therewith. The outer ring (412, 422) is fixed to the inner ring (411, 412) so as to rotate relative thereto. The bearings (41, 42) are spaced from each other along the axial direction. A conductive bearing housing (50) has a tubular shape surrounding the shaft (30) with an air gap therebetween and contacts at least two of the outer rings (412, 422) of the bearings. A stator (20) is provided so as not to be located between the shaft (30) and the bearing housing (50). A rotor (10) is provided so as not to be located between the shaft (30) and the bearing housing (50), and faces the stator (20) with an air gap between the stator and the rotor. |
