摘要:
The invention relates to an electric machine (2), in particular an electric motor, comprising a one-piece can (26) which is disposed between a stator (46) and a rotor (20), wherein the tubular casing (58) of said can, which is loaded with external pressure by a coolant (42) in a machine housing (10), is made of a fibre composite material (60). The casing thickness (68) of the can (26) is less than 2.5mm and greater than 0.5mm.

The invention relates to an electric machine (1), comprising a stator (11) and a rotor (10) in a machine housing (7), wherein said rotor is disposed on a motor shaft (4) supported on the B side in a bearing unit (14) which has a ball bearing arrangement (21, 22) and is disposed radially elastically and axially movably within the machine housing (7). The electric machine (1) is preferably coupled on the A side without bearings via a rigid shaft coupling (12) to a working machine (2), in particular to a hydraulic pump.

The invention relates to cooling jackets and/or heat exchangers, which are to be placed in contact with solid products that are to be cooled, especially with electrical machines with a rotor rotating inside or outside a stator, or in contact with reactors or containers. Said jackets and/or heat exchangers have an inner wall and an outer wall which form the boundary of a flow cavity that is provided with inlet and outlet means for a cooling medium and conducting means in order to form and/or limit at least one flow path for the cooling medium between the inner wall and the outer wall from the inlet means to the outlet means. According to the invention, opposing individual flat places or flat sections of the inner wall and the outer wall are in contact with one another within the confines of said walls and passages for the cooling medium remain between the contacting flat places of flat sections. One or more elevations and depressions alternate on one or more external sides or an outer casing of the inner or outer wall, wherein adjoining flat places or flat sections are permanently connected over individual joints and/or elongated joint sections.

An electric machine with a machine housing for accommodating a stator and a rotor with stator and/or rotor windings, which are connected to connecting lines for producing an electrical contact connection. An isolating plate, which covers a line channel for accommodating the connecting lines, has a number of insulating bushes, into which connecting pins are inserted which can be brought into contact with the connecting lines. In this case, the connecting pins with respect to the insulating bushes and preferably the insulating bushes are inserted into the isolating plate in position-coded or angle-coded fashion with respect to the isolating plate.
