摘要： The invention relates to an electrical machine (1) comprising a rotor (4) which is rotatably mounted around a rotation axis (5) extending in the axial direction (3) in bearing devices (16, 17), a stator (7) having two axial ends, an air gap between rotor and stator, an interior chamber (10) encompassing the stator (7) and rotor (4), a sleeve (11) encompassing a first part (111) which encloses the interior chamber (10), a frame (12) having a first (123) and a second (121) longitudinal support (123), a first (122) and a second (124) cross-support, and a dividing device (2) on the frame (12). The stator (7) comprises a fastening device (15) for connection to the frame (12) and the dividing device (2) can make the interior chamber accessible from the outside in a plane parallel to the frame (12). The invention further relates to a collection, to a frame (12), to a sleeve (11), or to a service or production method of such an electrical machine (1).

摘要： A device for lubricating an antifriction bearing of an electric motor includes a lubrication chamber located around a shaft of the electric motor and adjacent to the antifriction bearing when the shaft rotates. The lubrication chamber has a radial outer wall which is provided with at least one opening. An oil reservoir configured for arrangement on an exterior or an interior of the electric motor includes an oil pan and a ring-shaped or disk-shaped oil delivery member which directly or indirectly moves along on the shaft and is configured to run through the oil pan and to enable oil to be transported from the oil pan into the lubrication chamber, with oil being able to flow out of the lubrication chamber via the at least one opening back into the oil pan.

摘要： An electric machine includes an inner fan in an inner cooling circuit and an outer fan for producing an outer coolant flow that is separate from the inner cooling circuit. The inner and outer fans are connected to a common shaft of the electric machine and have opposite delivery directions along an axial direction of the electric machine. The outer fan is arranged in a fan housing which has an inlet opening for the inward flow of a coolant of the outer coolant flow, and includes an air directing device, which guides the coolant in a line section which extends in the radial direction of the electric machine from the inlet opening towards the outer fan.

摘要： A rotor of a rotary dynamoelectric machine incudes a magnetically conductive body, having substantially axially running slots distributed around the circumference. A squirrel cage includes electrical conductors which are arranged in the slots. The electrical conductors are electrically contacted at the two end faces of the rotor by short-circuit rings. The magnetically conductive body includes a base body and at least two further additional bodies, which axially adjoin the base body. A first one of the at least two additional bodies directly axially adjoins the end face of the base body, and a second one of the at least two additional bodies and optionally any further additional body axially adjoin the first additional body. The slots have radially exposed slot portions in the axial end regions of the rotor such that the conductors can be moved radially outward.
