Abstract
The brushless direct current motor comprises a housinga statorand a rotorwithin the housing, windings on the stator, sensors for sensing the position of the rotor relative to the stator and electronic circuitry for switching the current in the windings in response to outputs from the sensors to cause the rotor to rotate relative to the stator. The sensors and at least a part of the electronic circuitry are encapsulated in an electrically insulating and fuel resistant material in a container within the housing.
