Abstract
A vector control driving device is provided for an electric motor receiving an operating setpoint, with stator windings receiving a driving current and producing a rotating magnetic field, the windings generating a voltage at terminals of the motor, a rotor producing a magnetic field to follow the rotating magnetic field, the device generating current in a vector domain, and configured to carry out a transform of the current from the vector domain to a real domain allowing for generation of the driving current, and configured to carry out an inverse transform of a parameter measured in the real domain on the stator windings into a transform of the parameter in the vector domain, and comparing the value of the inverse transform of the parameter with a predefined maximum parameter value, which can drive the generating of the current in the vector domain. An automatic and adaptive defluxing method is provided.
