Electrical Machine
Abstract: An electrical pump or generator apparatus (10) comprises a sealed housing (11) having fluid inlet and outlet ports (17, 15) and an impeller (12) rotatably mounted inside a cavity of the housing (11), the impeller (12) being mounted on a shaft for rotation about an axis, the shaft being confined inside the sealed housing (11). An electric machine of the pump (10) has a stator (20) disposed outside the housing (11) and a rotor (29) sealingly disposed inside the housing (11). In use a rotating magnetic field extends through a boundary wall (14) of the housing (11) to magnetically couple the stator (20) and rotor (29) on opposite sides of thereof. The need for a shaft seal is thus avoided and the apparatus is more compact than conventional pumps and generators.
