Abstract
A motor assembly has an electric motor with a motor housing and an electronics unit. A first housing shell is formed as a motor carrier and has the motor housing fastened to it. A second housing shell is in the form of a cooling cover. An electronics carrier is arranged in sandwich-like fashion between the cooling cover and the motor carrier. The electronics carrier has, at the cooling cover side, a first, circumferentially encircling seal which seals off a first contact edge formed between the electronics carrier and the cooling cover and the electronics carrier has, at the motor carrier side, a second, circumferentially encircling seal which seals off a second contact edge formed between the electronics carrier and the motor carrier.
Claims12
A motor assembly, comprising:
- an electric motor having a motor housing;
- an electronics unit including:
- a first housing shell being a motor carrier and having said motor housing fastened thereto;
- a second housing shell being a cooling cover;
- and
- an electronics carrier sandwiched between said cooling cover and said motor carrier, said electronics carrier having, at a cooling cover side, a first, circumferentially encircling seal sealing off a first contact edge between said electronics carrier and said cooling cover, and said electronics carrier having, at a motor carrier side, a second, circumferentially encircling seal sealing off a second contact edge between said electronics carrier and said motor carrier;
- an electronic inverter circuit carried on said electronics carrier and being connected, in a terminal region of a motor carrier-side surface of said electronics carrier, by way of contact elements to phase terminals of said electric motor;
- and
- said terminal region being, by way of a secant-like internal web of said second seal, delimited in fluid-tight fashion with respect to a circuit region of the motor carrier-side surface of said electronics carrier, on which at least one electronic component of said electronic inverter circuit is arranged.
