This paper presents monitoring and diagnostic techniques for drivetrain components in hybrid electric vehicles (HEVs). The particular focus of this work is the gear box of the drivetrain and mechanical faults of the electric motor. Permanent magnet motor magnet failures and rotor eccentricities are investigated and diagnosed. For induction motors, the presented mechanical fault cases are electrical rotor asymmetries (defective bars and end rings) and rotor eccentricities, as well. Apart from stationary operation, the presented techniques can also be applied to transient operating conditions. Measurement results are presented and discussed.
