摘要： A submersible-rated motor with a non-drive end bearing housing that is incorporated directly into the motor housing in a single casting, a terminal plate assembly that includes a terminal box cast directly onto the non-drive end of the motor housing, a drive end seal housing that is configured to enclose an oil reservoir and a shaft seal assembly, and a drive end bearing housing that is mounted completely inside of the seal housing. The seal housing is sealed separately from the motor housing. Both the drive end bearing housing and the seal housing are piloted for concentricity with the drive end of the motor housing.

摘要： A generator assembly includes a generator shaft defining an interior vent space. A valve assembly is positioned within the vent space configured to selectively allow venting of air through the generator shaft. A radial vent is positioned within the valve assembly configured to prevent oil from flowing through the vent space during operation and release air through the vent space during shutdown.

摘要： A method provides power to a subsea equipment electrical system underwater, without a wet-mated electrical connection. The method includes temporarily coupling a rotary coupling element of a power source to the subsea equipment and turning that element to generate electric power on board the equipment. Subsea equipment that implements the method comprises: an on-board electric power generator connected to an electrical load such as a rechargeable battery to charge the battery when the generator is driven; and a rotary coupling element that is turned by an external drive to drive the generator. Alternative subsea equipment to implement the method comprises: a stator, but not a rotor, of an on-board electric power generator, which supplies current to the load when an externally-driven rotor is positioned adjacent to the stator and turned relative to the stator. A power source having a generator rotor is docked with the equipment for this purpose.

摘要： An electric motor is provided with an annular member supported by a cylindrical member of a front housing. The annular member includes an opposite part spaced from a surface of a ring member in a rotary shaft, which extends in the circumferential direction. The annular member includes first cover part opposed to first surface of the ring member, and second cover part opposed to second surface of the ring member. The first cover part and the second cover part are spaced from the ring member so that a pressure in a space sandwiched by the first cover part and the first surface is equalized with a pressure in a space sandwiched by the second cover part and the second surface.

摘要： A permanent magnet of a rotor core of a rotor includes a first recess and a second recess, which are formed in an outer wall to correct a dynamic balance of the rotor. The permanent magnet is a bonded magnet that is formed by molding a mixture material, which is a mixture of resin and magnetic powder. The first recess and the second recess are formed at the time of molding the permanent magnet. Furthermore, the first recess and the second recess are formed at two axial ends, respectively, of the permanent magnet.
