Abstract

An electric motor, in particular a printed circuit board, having a stator, and a linearly guided rotor. On the rotor, a bolt ring having a number of bolts is attached. A cycloidal disc is connected in engagement to the bolt ring. An electrical circuit is also provided having a printed circuit board and an electric motor which is attached to the circuit board.

First claim

What is claimed is:

1. An electric motor, in particular a printed circuit board, the electric motor comprising:
a stator;
a linearly guided rotor to which a bolt ring with a plurality of bolts is connected; and
a cycloidal disc connectable with the bolt ring, the bolt ring being disposed between the linearly guided rotor and the cycloidal disc.

2. The electric motor according to claim 1 , wherein the cycloidal disc is internally serrated.

3. The electric motor according to claim 1 , wherein the bolt ring is connected to a support, in particular integrally formed, which is attached to the rotor.

4. The electric motor according to claim 1 , further comprising a frame-like rotor having a central recess, wherein at least one outer edge is in particular toothed.

5. The electric motor according to claim 1 , wherein each bolt has a sliding sleeve.

6. The electric motor according to claim 1 , wherein the bolt ring includes between 8 and 15 bolts.

7. The electric motor according to claim 1 , wherein the stator comprises three or more electromagnets.

8. The electric motor according to claim 7 , wherein at least one of the electromagnets is electrically contacted with a delay circuit.

9. The electric motor according to claim 7 , further comprising a microprocessor for energizing the electromagnets.

10. An electrical circuit comprising a printed circuit board and an electric motor connected to the circuit board according to claim 1 .

11. The electric motor according to claim 1 , further comprising a support plate on which the bolt ring is formed.

12. The electric motor according to claim 11 , wherein the cycloidal disc is arranged parallel to the support plate and is recessed on a side facing away from the support plate.

13. The electric motor according to claim 1 , where the cycloidal disc comprises a plurality of indentations circumferentially surrounding the bolt ring.

14. The electric motor according to claim 13 , wherein some of the plurality of bolts engage with the plurality of indentations and some of the plurality of bolts do not engage with the plurality of indentations.

15. The electric motor according to claim 1 , further comprising a hollow flange attached to the cycloidal disc and extending through a recess in the linearly guided rotor.

16. The electric motor according to claim 1 , wherein the linearly guided rotor comprises:
a square frame having four outer edges;
a recess formed in a center of the square frame; and
an edge recess formed in each of the four outer edges.

17. The electric motor according to claim 16 , further comprising a plurality of electromagnets, each of the plurality of electromagnets being partially disposed within the four outer edges.

18. The electric motor according to claim 1 , wherein each of the plurality of bolts is cylindrically formed and comprises:
a core; and
a hollow sliding sleeve surrounding the core.

19. An electric motor, comprising:
a linearly guided rotor;
a bolt ring, with a plurality of bolts, connected to the linearly guided rotor; and
a cycloidal disc connectable with the bolt ring, the bolt ring being disposed between the linearly guided rotor and the cycloidal disc.

20. A switching module, comprising:
an electric circuit;
an electric motor fixed on the electric circuit, the electric motor comprising:
a linearly guided rotor;
a bolt ring, with a plurality of bolts, connected to the linearly guided rotor; and
a cycloidal disc connectable with the bolt ring, the bolt ring being disposed between the linearly guided rotor and the cycloidal disc.
