摘要： The subject matter of this specification can be embodied in, among other things, an electric motor health monitoring system that includes an estimator module configured to model one or more estimated motor values of an electric motor based on one or more motor control parameters and one or more motor control states, a non-transitory computer readable medium, and a fault detector module configured to (1) provide a fault signal based on the modeled one or more estimated motor values of the motor and a predetermined parameter threshold value, and (2) modify the non-transitory computer readable medium based on the fault signal.
