A driving circuit for an electric motor including multiple windings includes a sensing circuit to sense motor winding currents. A motor rotation angle signal is generated from the sensed currents and motor control voltages are generated as a function of the motor rotation angle signal. The motor windings are driven with motor drive voltages obtained by injecting into the motor control voltages injection pulses. The sensed currents include both torque components and injection components. The motor rotation angle signal is generated as a function of the injection components of the sensed currents.

Method of controlling electric motors, corresponding device and motor

Systems and methods are disclosed for controlling, diagnosing and prognosing the health of a motorized system. The systems may comprise a diagnostics system, a prognostic system and a controller, wherein the diagnostics system and/or prognostic system employs a neural network, an expert system, and/or a data fusion component in order to assess and/or prognose the health of the motorized system according to one or more attributes associated therewith. The controller may operate the motorized system in accordance with a setpoint and/or a diagnostics signal from the diagnostics system and/or prognostic information. Also disclosed are methodologies for controlling, diagnosing and prognosing the health of a motorized system, comprising operating a motor in the motorized system in a controlled fashion, diagnosing and/or prognosing the health of the motorized system according to a measured attribute associated with the motorized system, wherein the motor may be operated according to a setpoint and/or the diagnostics signal and/or prognosis.
