Abstract
A dynamic limitation device of a dynamic output parameter of an electric motor capable of receiving a working setpoint comprises: a generator of a dynamic maximum current proportional to a first working setpoint of the motor to supply the motor to generate a rotating torque of a shaft of the electric motor as a function of the first setpoint, a first estimator of a first dynamic output parameter of the electric motor, and a first dynamic limiter of the first output parameter of the motor, which comprises: a first comparator of the value of the first estimated parameter with a predefined maximum value of the first parameter, a first corrector to generate a first correction current, the value of which depends on the result of the comparison to be added to the dynamic maximum current to supply the motor. A dynamic limitation method implementing this device is provided.
