Abstract
A device for sealing off multiple grooves of a stator of an electric drive machine with respect to a rotor of the electric drive machine. The device includes a seal which is able to be inserted simultaneously into the multiple grooves, wherein the seal is designed as an electrical insulator. The seal is designed to seal off the grooves with respect to the rotor. Windings of an electrical coil are able to be arranged in the grooves. The seal is of integral or unipartite design.
Claims10
A device for sealing off multiple grooves of a stator of an electric drive machine and a rotor of the electric drive machine with respect to one another, the device comprising:
- a seal which is configured to be inserted simultaneously into the multiple grooves, wherein the seal is configured as an electrical insulator, and wherein the seal is configured to seal off the grooves and the rotor with respect to one another, wherein the seal includes multiple openings that are each sized to encapsulate windings of an electrical coil, wherein the openings are isolated from each other, wherein the seal is of integral or unipartite design, and wherein each opening is divided into recesses for accommodating the windings, wherein, for each opening, the windings in one recess are electrically insulated from the windings in another recess.
