| 摘要 |
The present invention relates to motors each having a rotor with a metal rotor frame, a metal rotation shaft, and a rotation shaft supporting member connected between the rotor frame and the rotation shaft for transmission of a rotating power from the rotor to the rotation shaft, and, more particularly, to a motor in which the rotation shaft supporting member is constructed of a metal and an insulating material, for insulating the rotation shaft from the rotor frame while enhancing a structural strength of the rotation shaft supporting member. The motor for preventing current leakage to a rotation shaft, having a rotor with a rotor frame of metal, a rotation shaft of metal, and a rotation shaft supporting member connected between the rotor frame and the rotation shaft to transmit a rotation power from the rotor to the rotation shaft, the rotation shaft supporting member includes a supporting portion of metal for receiving and supporting the rotation shaft, and an insulating portion for electric insulation between the rotor frame and the rotation shaft.
