Abstract

An electric drive includes a rotor and a stator in toothed-coil technology, wherein the stator has a number of individual tooth modules. A respective individual tooth module has a stator winding which is wound around an associated tooth, a control device which is designed to generate an activation signal for the stator winding, and a shielding device which surrounds the stator winding and the control device.

Claims (24)

1. An electric drive, comprising:

a rotor; and

a stator in toothed-coil technology, wherein the stator has a number of individual tooth modules, wherein each individual tooth module has:

a stator winding which is wound around an associated tooth,

a control device which is designed to generate an activation signal for the stator winding, and

a shielding device which surrounds the stator winding and the control device.

2. The electric drive as claimed in claim 1 , wherein

a respective control device has an electric fuse element.

3. The electric drive as claimed in claim 1 , wherein

a respective control device has a power semiconductor module and/or an electric energy store.

4. The electric drive as claimed in claim 1 , wherein

a respective control device has a device for detecting the rotor position.

5. The electric drive as claimed in claim 1 , wherein

a respective control device has an energy supply connection.

6. The electric drive as claimed in claim 1 , wherein

the electric drive has a superordinate controller which has a data connection to the control devices of the respective individual tooth modules.

7. The electric drive as claimed claim 1 , wherein

the shielding device has a housing made of sheet steel, wherein the housing partially or completely surrounds the stator winding and the control device.

8. The electric drive as claimed in claim 1 , wherein

the shielding device is formed from potting compound containing soft magnetic particles, wherein the potting compound partially or completely surrounds the stator winding and the control device.

9. The electric drive as claimed in claim 1 , wherein

the rotor is provided with markings for coding the rotor position on its circumference.

10. The electric drive as claimed in claim 1 , wherein

the rotor is in the form of a permanent magnet rotor or a reluctance rotor.
