Abstract: A dynamo-electric rotary machine includes a stator having a hollow-cylindrical, magnetically conductive body, which has grooves in the region of an inner casing surface of the magnetically conductive body. Electrical conductors are received in the grooves and electrically contacted by a short-circuit ring on an end side of the magnetically conductive body of the stator. The electrical conductors are electrically contacted on another end side of the magnetically conductive body by a plurality of inverter modules for controlling the respective electrical conductor. A rotor is arranged spaced apart from the stator by an air gap and designed as a squirrel-cage rotor. The rotor has short-circuit rings on its end sides, wherein the conductors and/or the inverter modules and/or the rotor and/or the short-circuit ring of the stator can each be cooled, at least in a section thereof, by a gaseous medium, in particular air.

Abstract: An active part of an electrical machine includes teeth, each having a tooth base, a tooth height, open or closed grooves between the teeth, and windings introduced into the grooves. Each winding encloses at least one of the teeth. The active part has a thickness, starting from the outer surface of the respective tooth bases and extending along the teeth, that is greater than the tooth height. The active part, starting from the respective tooth base up to a limit depth, which is not more than equal the tooth height, has a first material with a first magnetic permeability and starting from the limit depth a second material with a second magnetic permeability. The first magnetic permeability is greater than the second magnetic permeability. The limit depth is essentially half as great as the tooth height.

Abstract: The aim of the invention is to better compensate for specifiable forces on a magnetic mounting. This is achieved by a magnetic mounting device with a first magnet device (10), which is designed in an annular manner and which has a central axis, for retaining a shaft on the central axis in a rotatable manner by means of magnetic forces. The magnetic mounting device additionally has a second magnet device (12), which is independent of the first magnet device (10), for compensating for a specifiable force acting on the shaft. In this manner, the magnetic mounting device can compensate for the gravitational force or forces based on imbalances.
