An electrostatic shielded induction motor (ESIM) is on solution to Shaft-Voltage, as the insulation reduces voltage levels below the dialectric breakdown effectively stopping bearing degredation and offers one solution to accelerated bearing wear caused by fluting induced by pulsewidth modulated (PWM) inverters.
