Abstract

An integrated brushless DC wet motor pump unit comprises a pump, a motor and a motor controller all contained within a housing. The motor includes a stator having stator coils fixed in relation to the housing and a motor rotor surrounding the stator coils and supported for rotation in the housing. A drive coupling drivingly couples the motor rotor to a rotating pump element, and the drive coupling, rotating pump element and motor stator are radially supported on a central support member. The various motor and pump components are assembled into the housing from one axial end of the housing, with the motor rotor, drive coupling and rotating pump element having axially telescoping anti-rotation elements connecting the same for common rotation. The motor rotor includes a radially outer back-iron and a rotor magnet that is insert molded into the rotor back-iron that is rotatably supported at its outer diameter by a journal surface on an inner diameter surface of the housing. A sensor printed circuit board includes at least one sensor for sensing passage of the magnetic poles of the motor rotor for electronic commutation and motor speed control. Materials, fabrication, further components and assembly of the various pump unit components are described.
