摘要： An electrical connecting device for a machine includes a fitting element (2) to be fitted in an aperture (1a) of a wall element (1), at least one connecting element (3) which has a first end (3a) with a first connection unit (3b) for an electric cable which is situated outside the wall element (1), a second end (3c) with a second connecting element (3d) for an electric cable which is situated within the internal space, and an intermediate portion (3e) to be fitted in an aperture (2c) which runs through the fitting element (2); a sealing (5) makes a tight connection between the connecting element (3) and the fitting element (2) in the aperture (2c). The fitting element (2) is made integrally from a first material. The connecting element (3) is made integrally from a second material. The connecting element (3) and the fitting element (2) are provided with mutually cooperating surfaces (2c1, 2c2, 3e1, 3e2) which define a predetermined fitting position for the connecting element (3) in the aperture (2c).

摘要： The present invention relates to an arrangement for cooling of an electrical machine (3). The electrical machine (3) comprises a rotor (5) rotatably arranged around a rotation axis (4a), a stator (6) including a stator winding (6b) arranged radially outside of the rotor (5), a housing (2) enclosing the rotor (5) and the stator (6), at least one drain hole (11) configured to drain a cooling fluid from the housing (2), at least one spraying device (8-10) configured to spray cooling fluid on the stator winding (6b) and a pump (14) configured to pump cooling fluid to the spraying device (8-10). The arrangement comprises a control unit (18) which is configured, when the electrical machine (3) is in operation, to receive information of the temperature in at least one position of the stator winding (6b) and to control the pump (14) such that it pumps a flow rate of the cooling fluid to the spraying device (8-10) which is related to the estimated temperature of the stator winding (6b).

摘要： A propulsion system for a vehicle has output shaft (2) of a combustion engine (1), which is connected to a first component (9) of a planetary gear so that they rotate at a first speed (n1). An input shaft (3) of a gearbox (4) is connected to a second component (11) of the planetary gear so that they rotate at a second speed (n2). An electrical machine is connected to a third component (10) of the planetary gear so that the third component (10) rotates at a third speed (n3). A control unit (17) estimates in appropriate operating situations a desired speed (n2) for the gearbox input shaft (3). The unit receives information about the speed (n1) of the engine output shaft (2). It causes the electrical machine to give the third component (10) of the planetary gear a speed (n3) which in conjunction with the speed (n1) of the engine output shaft (2) results in the gearbox input shaft (3) assuming the desired speed (n2).
