    • Procedure for estimating the electrical drive speed and position of a permanent magnet rotor of a brushless electrical linear or rotating motor, especially for a drive control circuit, using multi-phase current measurements on the motor, whose measurement values, depending on the estimated position, are transformed into a rotor-related d,q reference frame i.e. into a direct current vector component and a quadrature current vector component, and the direct and quadrature vector components of current and a voltage, together with the estimated speed, are fed as input variables to a mathematical motor model, and the motor model generates a first output variable and a second output variable, whereby the first output variable in the d,q reference frame corresponds to the d or direct vector component as well as to a position estimation error, and the second output variable in the d,q reference frame corresponds to the q or quadrature component as well as to a speed estimation error, and the two output variables are fed to a tracking controller for estimating and outputting the position and/or speed, whereby from the motor model a third output variable is computed, by a) the direct and quadrature vector components of current each being weighted with a direct and quadrature inductance of the motor, b) the third output variable being formed from the difference between the two weighting results, whereby the third output variable is fed to the tracking controller for processing to estimate the position and speed.
