The article is devoted to the problem of developing highly dynamic flux observers for three-phase inductor motors. The synthesis of the flux observer is based on the analysis of the instantaneous powers of the motor stator by the vector control of drives. The observation algorithm lacks integral, differential and iterative methods of mathematics. The proposed observer algorithm is implemented in a vector-matrix form for its simplest integration into the modern vector control of electric drives. The observer provides stability and high precision in drives with direct torque control, in which the variation in the angle of the spatial voltage vector of the inverter is much higher than in drives with pulse width modulation. The proposed observer algorithm can be used in cost optimized drives, because its implementation does not require “exclusive” resources of microprocessor control units. The paper presents a time invariant observer algorithm that provides high precision of the observed flux at low inductances and low voltages of the inductor motor. The measured and observed moments of the reluctance motor during the acceleration of the drive were analyzed.
