An electric fluid pump, rotor unit therefore, and methods of constructions thereof are provided. The fluid pump includes a stator unit configured to generate a magnetic field in response to a control signal. A rotor unit is received within the stator unit, wherein the rotor unit is configured to rotate about a central rotor axis in response to the magnetic field generated by the stator unit. The rotor unit includes a plurality of magnets contained in through openings of a carrier assembly having first and second carrier members, wherein the first and second carrier members are fixed to one another by bond joints.

An electric water pump, and more specifically an electric water pump having an improved wet sleeve so that the water pump is free of a housing. The electric water includes a pump rotor having a shaft. A wetsleeve surrounds the rotor and has a cap, a sleeve that houses the rotor, and a seat in communication with the shaft of the rotor so that the seat assists in supporting the shaft a stator. Surrounding the wet sleeve and the rotor is a volute covering an upper portion of the rotor, wet sleeve, and stator. The electric water pump further includes a rubber boot covering a lower portion of the rotor, wet sleeve, and stator and is in communication with the volute forming a cover.

A method of linking commutator bars of a commutator for a motor wherein N is the number of magnetic poles of the motor and N is an even integer greater than 2. The method include a) arranging a plurality of commutator bars to be generally equally spaced in a circular arrangement to define the commutator, each commutator bar having a tang extending therefrom, b) contacting an end of a continuous, insulated conductive member to a tang, c) moving the member to contact a second tang which is disposed at an angle of 720&deg;/N from the previously contacted tang to form a link, and when N is greater than four, repeating this step until N/2&minus;1 links are created, d) moving the member to contact a tang which is immediately adjacent to the second tang contacted in step (c) such that the member defines a bridging portion between the adjacent tangs, e) repeating steps (c) and (d) and until all tangs have been contacted by the member, and f) cutting the bridging portion between adjacent tangs.
