First Claim
Patent Images
1. An electrical machine configured to operate at a power range of several MVA comprising:
- a rotor configured to rotate about a rotor axis and including a rotor lamination stack;
a stator including a stator lamination stack concentrically surrounding the rotor lamination stack, wherein a ring-like air gap separates the rotor lamination stack from the stator; and
an air gap monitoring device extending through the air gap in an axial direction and configured to detect at least one of a change in a rotor geometry and a presence of debris in the air gap.

Abstract
An electrical machine configured to operate at a power range of several MVA includes a rotor is configured to rotate about a rotor axis. The rotor includes a rotor lamination stack. A stator includes a stator lamination stack concentrically surrounding the rotor lamination stack, wherein a ring-like air gap separates the rotor lamination stack from the stator. An air gap monitoring device extends through the air gap in an axial direction and is configured to detect at least one of a change in a rotor geometry and a presence of debris in the air gap.
