    摘要: A brushless DC motor including a housing having an end cap secured thereto. The housing encloses a rotor, a stator and a rotationally displaceable commutation board having sensors secured thereon and spaced around the periphery of the rotor. An external rotational force is applied to the commutation board for displacement of the sensors to various positions whereby varying feedback signals are generated by the positioning of the sensors relative to the rotating rotor. The commutation board is secured in a fixed position in response to feedback signals indicative of optimum sensor position being determined. The rotation of the commutation board and the securing of the sensors in the desired fixed position is accomplished without requiring the removal of the end cap and with the DC motor operating.

    摘要: A light-weight electric motor driven fluid pump assembly having a molded thermoplastic housing of two parts which form a fluid impervious rotor chamber, a stationary shaft journalled in the housing parts within the chamber and carrying a magnetic rotor and a fluid impeller driven thereby. The housing parts also define inlet and discharge ports in communication with the rotor chamber adjacent the impeller blades. One portion of the housing of one housing part defines a cylindrical thin walled tubular configuration with a cylindrical exterior surface for mounting a stator thereabout. The housing parts are welded together at mating surfaces with the result that neither static nor dynamic seals are required in the assembly.

    摘要: A wiring connecting system having superior electrical transmission performance with reduced cross talk and improved lacing and termination features is disclosed and includes a base, a wire strip mountable to the base, a connecting block for housing a plurality of electrical contacts and a plurality of cross talk barriers disposed within the connecting block for isolating pairs of the electrical contacts. The wire strip has a plurality of first and second posts alternating along its length. The second posts have a greater width than the first posts. A connecting block for housing a plurality of electrical contacts mounts onto the wire strip. An upper end of the connecting block includes a plurality of first and second teeth alternating along its length with the second teeth have a greater width than the first teeth. The electrical contacts extend from the lower end of the housing to generally align with the openings of the wire strip. A plurality of barriers for electrically shielding pairs of the electrical contacts are disposed within the connecting block housing and substantially surround respective pairs of the electrical contacts. A plug for connecting a cable having a plurality of wires to the connecting block is also disclosed.
