Abstract:
This motor (1) has a rotor (2), a stator (3), a first non-conductive member (4A), a second non-conductive member (4B), and a conductive case (5). A first conductive outer race (23B) of a first bearing (23) is insulated from a first housing (51) of the conductive case (5) by the first non-conductive member (4A). A second conductive inner race (24A) of a second bearing (24) is insulated from a conductive shaft (21) of the rotor (2) by the second non-conductive member (4B). A first conductive inner race (23A) of the first bearing (23) is in contact with the conductive shaft (21). A second conductive outer race (24B) of the second bearing (24) is in contact with a second housing (52) of the conductive case (5).
