Abstract
The disclosure describes an electric drive assembly having an electric motor which is arranged in a motor housing and a fan which is arranged on an end face of the motor housing. The fan generates a cooling air flow that removes heat from the electric motor. An electronic controller with electronic components controls or regulates the electric motor. A box-shaped motor panel sits on the motor housing and houses the electronic components. The heat generated during operating of the electronic components can be discharged by means of the motor panel to a heat sink which is in thermally conductive contact with the motor panel.

1-28. (canceled)
An electric drive arrangement comprising:
- an electric motor arranged in a motor housing;
- a fan positioned adjacent to an end face of the motor housing and generating a cooling air flow for dissipating heat losses of the electric motor;
- an electronic controller for controlling or regulating the electric motor;
- and
- a box-shaped motor panel supported on the motor housing and accommodating the electronic controller;
- wherein heat generated by the electronic controller during operation can be discharged by means of the motor panel to a heat sink which is in thermal conducting contact with the motor panel.
The cooling device for an electric drive arrangement having an electric motor and electronic components for controlling and regulating the electric motor, the cooling device comprising:
- a motor housing in which the electric motor is arranged;
- a fan positioned adjacent an end face of the motor housing and generating cooling air flow for dissipating heat losses of the electric motor;
- and
- a box-shaped motor panel supported on the motor housing and accommodating electronic components for controlling or regulating the electric motor;
- wherein heat generated during operation of the electronic components can be discharged by means of the motor panel to a heat sink which is in thermal conducting contact with the motor panel.
A blade angle adjustment drive for adjusting at least one rotor blade for a wind turbine about a blade axis for generating electric power, wherein the rotor blades extend transverse to a rotor axis, the blade angle adjustment drive:
- an electric motor arranged in a motor housing;
- a fan positioned adjacent to an end face of the motor housing and generating a cooling air flow for dissipating heat from the electric motor;
- an electronic controller for controlling or regulating the electric motor;
- and
- a box-shaped motor panel supported on the motor housing and accommodating the electronic controller;
- wherein heat generated during operation of the electronic controller can be discharged by means of the motor panel to a heat sink which is in thermal conducting contact with the motor panel.
