Method of Sensorless Determination of Mechanical Parameters and Information-Measuring System of Valve-Inductor Drives

This article explores sensorless control systems for a valve-induction motor. The basic methods of sensorless valve-induction motor control are considered. Disadvantages of determination of the speed of the engine on the output signal of the comparator at the use of a method of measurement flux linkage are revealed. A method for determining the speed based on the determination of the coordinated positions of the stator and rotor teeth by detecting peaks of the inductances of the motor phases is proposed.
