Abstract: The invention relates to a compressor for refrigerant having a compressor housing, said compressor housing being provided with a suction inlet and a pressure outlet, said compressor comprising a compression unit, arranged in a compression housing section of said compressor housing and an electric motor arranged in a motor housing section of said compressor housing, said electric motor comprising a stator arranged within a stator receiving sleeve of said motor housing section and a rotor surrounded by said stator and arranged on a drive shaft of said electric motor for rotation about an axis of rotation together with said drive shaft, said stator comprising a stator core having a stack of laminations and extending parallel to said axis of rotation from a first front side to a second front side, said stator having windings extending through said stator core and forming end windings arranged in front of said front surfaces, and a channel for guiding at least a portion of said refrigerant entering through said su

Abstract: A method of vertically assembling a generator of a wind turbine is provided. The method includes A rotor part is arranged on a horizontal assembly which supports components of the generator such that a rotational axis of a component is essentially vertical during assembly, and the assembly support is configured to allow access to an interior of a generator component during the assembly procedure; a stator part is arranged in the rotor part; and the stator part is joined to the rotor part. An assembly arrangement for a vertical assembly of a generator of a wind turbine is provided. The assembly arrangement includes a horizontal assembly support for supporting components of the generator such that a rotational axis of a component is essentially vertical during assembly, and the assembly support is configured to allow access to an interior of a generator component during the assembly procedure.

Abstract: A rotating electric machine for driving a drive object is provided. The rotating electric machine includes a motor case, a stator, a winding, a rotor, a shaft, a base cap, an end cap, an output rod, base cap holes, end cap holes, and through bolts. The base cap has base cap flanges formed on a circumferential edge and extending radially-outward beyond an outer wall of the motor case. The end cap has end cap flanges formed on a circumferential edge and extending radially-outward beyond the outer wall of the motor case. Base cap holes are formed on the base cap flanges and end cap holes in axial alignment with the base cap holes are formed on the end cap flanges. Through bolts fasten the base cap flanges to the end cap flanges.

Abstract: A generator support system for a centerline mounted generator includes a generator support member configured and disposed to support a generator upon a support surface. The generator support member includes at least one lifting element having a lifting surface that faces the support surface.

Abstract: The invention relates to a generator stator configuration, comprising a stiffened stator core having a multitude of stator plates, which have stator teeth on the radial inner periphery of the stator core, each stator plate having a material bond to an adjacent stator plate and/or to a stiffening element on the radial outer periphery on at least one connection point; and a spring-elastic support structure to implement an elastic foundation connection for the stiffened stator core.

Abstract: A rotating electrical machine includes a frame, a flange, a rotor, a stator, and a plurality of reinforcing bars. The frame has a plurality of side surfaces surrounding a space to form a substantially polygonal shape in a plane perpendicular to an axial direction of the frame. The side surfaces have a first side surface and a second side surface opposite to the first side surface. The frame has an end portion in the axial direction. The flange is provided at the end portion of the frame. The rotor is provided in the space and includes a shaft that is rotatably supported by the flange. The stator is provided in the space to be fixed to an inner section of the frame and to surround the rotor. The reinforcing bars intersect each other and are provided on the first side surface and the second side surface, respectively.
