摘要： Sensorless control of an induction motor, such as for electric vehicles, in which the speed of an induction motor is determined without encoders or other shaft transducers. When the applied frequency is null, the injection of a triad of direct currents in the stator phases supplies a stationing torque that is opposed to motion. The maximum stationing torque depends on the injected current width. It can be too low, such as if the vehicle is loaded and/or on a grade, or too high if the vehicle is on a plane. With embodiments, one can monitor, at defined time intervals, the speed of the vehicle when the applied frequency is null and with which such dichotomy can be solved. Embodiments can be applied generally to every occurrence of vehicle control loss in order to carry out its efficient recovery in line.

摘要： This invention relates to sensorless control (i.e. without encoder at the motor shaft) of an induction motor (AC asynchronous motor). In particular, the invention comprises a method for a direct measurement of the electromotive forces (EMF) at the stator of the motor to allow for the regulation of the speed of the motor in a wide range, including the very low frequency range. The method provides the accurate measurement of the EMF at the stator in such a way that the direct control of an induction motor will get simpler, in terms of less calculation and, overall, in terms of accuracy and consistancy of the results, thanks to the availability of a direct measurement of the EMF instead of a bare estimation thereof. To enable the direct measurement, the employment of at least two sensor windings (sensor coils) is needed each one mutually coupled with the stator phase of the motor.

摘要： The invention is applied to the field of industrial controls for electric motors and more precisely refers to a process for measuring phase currents of an inverter or a DC controller consisting in detecting the temperature of a copper path made with IMS (Insulated Metal Substrate) technology and the like, used as shunt and that is the extension of a pre-existing adduction line towards a motor or towards the supply line or towards power devices, and in compensating through software the path drop in order to have an accurate measure of the current crossing it. A heat sensor is applied next to or over such copper path to detect its temperature. This latter one will also be assumed, with an acceptable degree of approximation, as the power transistors temperature.
