Abstract

Induction motors are widely used in industry due to their low price, reliability and high efficiency. Methods for regulating the rotation frequency of induction motors are presented. Described is the principle of the V/f method and the main operation of the components used for its realization. The study is performed in Matlab/Simulink environment for a specific motor using a pulse-width modulator, an inverter, and a V/f ratio control unit. Results from MATLAB simulation for the engine’s shaft rotation frequency and its electromagnetic moment are obtained.

Keywords

Model, Simulink, induction motor, V/f control
