Problems solved by technology

[0008] In the case of installation of the electrical machine components, especially the cooling cover, which is arranged next to another heat sink, the problem arises here that the cooling cover cannot dissipate heat to the surroundings by means of convection
This prevents heat removal from the motor electronics, which can become hot or overheat during operation, which can sometimes lead to irreparable damage to the electronics

Embodiment Construction

[0036] figure 1 An electrical machine assembly 2 for an actuator 4 of a motor vehicle transmission 6 , in particular a direct-shift transmission, is shown. The electromechanical assembly 2 of the actuator 4 , also referred to below as the transmission actuator, comprises an elongated electronics unit 8 with a plug-in connector 10 projecting on the narrow side, and an electric motor 12 fastened to the electronics unit 8 .

[0037] The electronics unit 8 comprises a first housing shell in the form of a motor base 14 , a second housing shell in the form of a cooling cover 16 and an electronics base 18 which is sandwiched between the motor base 14 and the cooling cover 16 . The plug-in connector 10 is here integrally formed on the end side of the electronics mount 18 . The converter circuit 20 of the electronics base 18 is connected in an electrically conductive manner by means of the plug connector 10 to a motor vehicle electronics not shown in detail, or to a motor for energiz...

Abstract

A motor structure assembly 2 has an electric motor 12 with a motor housing 24 and an electronics unit 8. The electronics unit comprises a first housing shell formed as a motor carrier 14 and having the motor housing fastened to it. The electronics unit also comprises a second housing shell in the form of a cooling cover 16, and an electronics carrier 18 arranged in sandwich-like fashion between the motor carrier 14 and the cooling cover 16. The cooling cover and the motor carrier 14 exhibit greater thermal conductivity than the electronics carrier 18. The cooling cover 16 and the motor carrier 14 are coupled to one another in heat-conducting fashion at at least one abutment surface. The present invention also relates to an actuator 4 having the above motor structure assembly and a motor vehicle transmission 6 possessing the above actuator.

Description

technical field [0001] The invention relates to a motor assembly with an electric motor including a motor housing and an electronics unit. The invention also relates to an actuator, in particular a transmission actuator for a motor vehicle having such an electric machine assembly, and a motor vehicle transmission provided with such an actuator. Background technique [0002] WO 2013 / 037454 A2 discloses an electric motor which can be a component of an actuator for a motor vehicle transmission, in particular a direct shift transmission (DSG). In the case of hydraulic actuators, an electric motor can be used to drive a hydraulic pump. [0003] The known electric motors have for this purpose a cylindrical motor or stator housing, on which the stator subassembly housing with the rotating field winding is fixedly mounted, and the rotor is rotatably movable together with a rotor shaft fixed relative to the rotor. It is supported on the motor or stator housing in the same way. For...
