  • Wet rotor pump motor stator sealing liner
    Patent number: 8920142
    Abstract: A sealing liner for use in a pump motor incorporates a radially enlarged portion at one end, and a radially smaller portion extending from the one end to an opposed end. A length of the overall sealing liner including the radially smaller portion and the radially enlarged portion is defined as a first length. A length of said radially enlarged portion is defined as a second length. A ratio of the first length to the second length is between about 6.5 and about 8.5. A stator assembly, a pump and a method are also disclosed.
    Type: Grant

  • Generator rectifier assembly with ease of assembly features
    Patent number: 7944100
    Abstract: A rectifier assembly includes first and second housings surrounding a pair of electrical rings. Each of the electrical rings communicates with a pin. Bolts secure a spring to hold diodes against an inner wall of the electrical rings. The first housing includes openings opposed to the bolts to allow access to the bolts for tightening the bolts to hold the spring, and bias the diodes against the inner periphery of the electrical rings. A rotor balance assembly, a generator, and a method of assembling a rectifier assembly are also disclosed and claimed.
