Abstract
A drive includes an electric motor, a converter, and an intermediate part arranged between the electric motor and the converter. A bottom part is connected to the intermediate part in a thermally conductive manner, a top part set apart from the intermediate part is connected to the bottom part in a thermally conductive manner, and the top part has cooling fins.
Claims23
A drive, comprising:
- an electric motor;
- a converter;
- and
- an intermediate part arranged between the electric motor and the converter;
- wherein a bottom part is connected to the intermediate part in a thermally conductive manner, a top part set apart from the intermediate part is connected to the bottom part in a thermally conductive manner, and the top part having cooling fins;
- and
- wherein the intermediate part includes uninterrupted threaded bores adapted to receive screw parts that press the bottom part toward the intermediate part.
