Abstract: A multi-phase electric motor includes a stator winding. The multi-phase electric motor is controlled by regulating a current flowing in the multi-phase electric motor in response to an applied voltage. An overload condition of the multi-phase electric motor is detected by monitoring a thermal increase of the value of a stator resistance of the stator winding of the multi-phase electric motor during a steady state condition of said multi-phase electric motor in which the current flowing in the motor has constant phase, and the motor is operating at constant load with constant speed.

Abstract: 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.

Abstract: An analog-to-digital converter device may include an input multiplexer circuit having analog input terminals configured to receive a respective plurality of analog input signals. The input multiplexer circuit may be responsive to a first select input. The device may also include a trigger multiplexer circuit having input terminals configured to receive respective triggering signals. The trigger multiplexer circuit may be responsive to a second select input. Analog-to-digital converter circuitry may be configured to convert the selected analog signal into a digital signal. A sequence arbiter may be coupled to the first and second select inputs and may have input terminals configured to receive a respective plurality of conversion sequence configuration signals. The sequence arbiter may be configured to manage each conversion sequence of the analog-to-digital converter circuitry based upon the relative conversion sequence configuration signal received, and control the conversion sequences.
