V. S. Motor Assembling Plant

Abstract

As the industries develop and diversify, rather than the motors with fixed revolution, the variable speed motors of large variable speed ratio and easy maintenance and operation have been in greater demand. The V.S. motor is largely divided into the induction motor part which is a driving motor, the V.S. coupling part consisting of the fixed speed rotating part directly connected to the driving motor and the accelerating part connected to the load side, and the speed controlling part, which serves the purpose of ensuring that a deviating voltage is fed back to the input of an amplifier by comparing at all times the- detected voltage fed back from the tachogenerator and proportional with the voltage and loaded speed set by the control board.
