Abstract
A shaft voltage reduction structure is mounted on an electric machine having a bearing house and a rotor shaft rotatably connected together, and includes an electrically conductive main body, at least one electrically conductive bearing, and an electrically conductive shaft. The conductive main body is mounted to a bottom of the bearing house and includes a conductive shaft barrel projected from a center thereof. The conductive shaft barrel internally defines a shaft receiving hole, in which the conductive bearing is received. The conductive shaft includes a connecting end and a pivotal end connected to the rotor shaft and the shaft receiving hole, respectively. A shaft voltage across the rotor shaft of the electric machine is guided by the conductive shaft to release in a closed loop formed among the conductive main body, the conductive bearing and the bearing house, so as to reduce the shaft voltage of the electric machine.
