    摘要: A motor system is disclosed comprising: an electrical conductor in the form of a coil or winding (2a-2c); an electrical insulator (10a-10c) insulating the electrical conductor; a discharge sensor (12a-12c) arranged and configured to measure a parameter indicative of an electrical current in the insulator; and a voltage controller (15a,30a) for controlling a voltage signal applied to the electrical conductor based on a value of the parameter measured by the discharge sensor.
