Abstract:
1. A motor comprising; a stator, a rotor, windings on the stator, sensors for sensing the position of the rotor relative to the stator, electronic circuitry for switching the current in the windings in response to outputs from the sensors so as to cause the rotor to rotate relative to the stator, a housing including at least one end cap and a rear housing part accommodating the stator the rotor, the sensors and the electronic circuitry, and a bearing sleeve fixed to the housing for supporting the rotor and for attachment to a fuel pump which is outside the housing, wherein the sensors and at least part of the electronic circuitry are encapsulated in an electrically insulating and fuel resistant material in a container within the housing, and wherein the container has an internal sleeve through which a shaft of the rotor extends and through which fuel from the fuel pump can flow.
