Abstract
A method for controlling a motor by an inverter and by a vectorial technique, comprising the following steps: determining the value of a quadrature current Iq necessary for said motor to generate the desired torque; calculating the value of a direct current to be supplied to the motor by an equation as a function of the phase of the current vector on which the torque constant of the motor depends; calculating the power current of said motor from the direct current and the quadrature current; supplying the power current to the motor through the inverter.

11. A device for controlling a motor comprising:
-
at least one inverter, to supply said motor with an electric power; and elaboration means working on said inverter to control supply of a power current to said motor, wherein said elaboration means are susceptible to calculate said power current by a direct current Id and a quadrature current Iq, said quadrature current Iq being fixed by a torque constant which said motor has to generate, said direct current Id being calculated by said elaboration means by equation
