  • Three phase converter fed motor having a shielding device to eliminate capacitive current in stator slots
    Patent number: 6756712
    Abstract: A device for preventing bearing damage from currents through a three-phase motor is provided, including a shield for winding and copper wire within each stator slot of a motor. The shield includes an electrically conductive layer which is insulated from the winding and from the laminated stator core of the three-phase motor. The conductive layer is grounded or conductively connected to the laminated stator core of the three-phase motor on only that side on which the three-phase current is fed to the winding of the motor.
