Electric motor, elevator with a car movable by an electric motor, and elevator with a car and with an electric motor for movement of a guide element relative to the car
First Claim
1. An electric motor having a primary part for generating a traveling magnetic field and a secondary part for providing a static magnetic field, wherein the secondary part and the primary part are movable relative to one another under an effect of the traveling magnetic field, the secondary part comprising:
- a substrate;
a conductor track applied to said substrate in a layer structure, and wherein said conductor track can be supplied with an electric current for generating the static magnetic field.

Abstract
An electric motor includes a primary part for producing a traveling magnetic field and a secondary part for providing a static magnetic field, wherein the secondary part and the primary part are movable relative to one another under an effect of the travelling magnetic field. The secondary part has a device with a substrate and a conductor track, which track is applied to the substrate, in the form of a layer structure, wherein the conductor track can be supplied with an electric current for the purpose of producing the static magnetic field.
