Abstract
A drive apparatus for a washing machine includes an electric motor, a drive shaft connected to the electric motor for rotary drive purposes and electronics for controlling operation of the electric motor. In order to achieve a compact construction, the electric motor and the electronics are integrated in a common unit. In order to increase operational reliability of the drive apparatus together with a simple construction, the common unit has a wall which is thermally coupled both to the electric motor and to the electronics and serves to dissipate heat. The electronics have a temperature sensor for detecting the temperature of the wall. Both the temperature of the electric motor and the temperature of the electronics can be monitored with this one temperature sensor.
