摘要： A canned motor includes a stator with a laminated core and a winding with winding heads, and including a rotor, which is mounted so as to be rotatable relative to the stator, and a can element, which is arranged between the stator and the rotor, and a support ring, which is coupled to the can element. The support ring on its own and/or together with the can element provides a support section which extends at least partially axially adjacent to the laminated core. The support section lies with a seal section against a seal device such that a rotor space is sealed off in coolant-tight fashion with respect to a stator space.

摘要： An apparatus for handling fluid within an at least partially electrically powered vehicle, with: an apparatus housing including a first housing section and a second housing section. The first housing section and the second housing section are adjacent to each other by a fluidically impermeable contour wall. The contour wall includes a side oriented toward the first housing section and a side oriented toward the second housing section, a first fluid handling element and a second fluid handling element. The first fluid handling element and the second fluid handling element include a first element for generating a controllably variable magnetic field arranged in the first housing section, and a second element movable by the generated magnetic field and arranged in the second housing section. The fluidically impermeable contour wall is continuously configured between the first fluid handling element and the second fluid handling element.

摘要： An electric motor comprises a stator presenting a first surface. A rotor is rotatable relative to the stator. The rotor presents a rotor raceway disposed in spaced relationship with the first surface of the stator. The first surface of the stator defines a plurality of slots in spaced relationship with one another to define a plurality of spaced teeth between the slots. At least one electrical conductor is disposed in each of the slots and configured to selectively create a moving magnetic field for acting upon the rotor for providing rotational movement of the rotor. A portion of the at least one electrical conductor extends substantially into radial alignment with, or past the first surface of the stator to at least partially define a stator raceway of the stator for engaging the rotor raceway of the rotor during relative radial movement between the rotor and the stator.

摘要： In a first aspect, a stator structure for an electrical machine is provided. The stator structure comprises a circumferential support having an external rim to support a plurality of electrical windings. The circumferential support comprises an air entrance, an air distribution channel and a plurality of axial air openings. The air entrance provides a passage between the air distribution channel and an outside of the stator structure. The air distribution channel extends through a portion of the circumferential support to circumferentially distribute an air flow from the air entrance. The plurality of axial air openings provides a passage between the air distribution channel and an outer side of the external rim to guide an air flow from the air distribution channel to the outer side of the external side. The plurality of axial air openings comprises an aperture, wherein the apertures are sized and spaced such that the air flow is substantially uniform along the circumference of the outer side of the external rim. In a further aspect, an electrical generator comprising a stator structure according to any of the examples herein described is provided.
