Abstract
In order to prevent bearing currents, particularly in converter-operated traction motors (1), the housing (11) is grounded via a grounding capacitor (Cground).
Claims7
A traction motor (1) in vehicles with an electric or diesel-electric drive, the traction motor (1) which is mounted in a housing (11) being grounded, characterized in that the traction motor (1) is grounded via at least one grounding capacitor (Cground).
The traction motor (1) as claimed in one of the preceding claims, characterized in that the electrical voltage is monitored at at least one bearing (10) as a measured variable of a functionally capable grounding connection via the grounding capacitor (Cground).
Dependencies are inferred from the claim text.
