This paper discusses the advantages and disadvantages of the thyristor voltage regulator induction motor is compared to the frequency converter. Studies thyristor voltage regulator induction motor with closed loop speed on a signal from the neural network observer speed. Principle of construction and method his training was reviewed. The input to the neural network signals from the sensors are fed current, voltage and torque, which estimates the rotation speed of the motor shaft. Refined model of thyristor voltage regulator was developed that allows you to adjust the speed of the motor by changing the opening angle of the keys. The adequacy of the model is established by means of modular and quadratic quality assessment, obtained by transient of asynchronous electric drive with the closed speed circuit by signals from the observer.
