In a general aspect, a method can include detecting, by a motor controller, an operating fault associated with operation of a powertrain of an electric vehicle. The powertrain can include a permanent magnet motor, a multi-phase inverter that is operationally coupled with the permanent magnet motor, and a rotational position sensor that is operationally coupled with the permanent magnet motor. The method can further include determining a classification of the operating fault and determining a present speed of the permanent magnet motor. The method can also include, in response to the detection of the operating fault and, based on at least one of the classification of the operating fault and the present speed of the permanent magnet motor, performing, by the motor controller, a fault reaction operation.
