In the paper the novel universal motor driver using three different modulation method of output waveform has been presented and discussed. It should be noted that in today’s world, most of driver of electrical motors are consist of four or six transistors forming appropriate bridges. Appling specified modulation methods enable to drive both single- and three-phase induction and synchronous motors of any kind. The construction of typical transistor bridge that consists of six transistors can be also used to control the direct current motors by switching off one of the pairs of transistors. In this paper the process of construction of universal motor driver has been presented, in which has been implement the modified method of Sinusoidal Pulse Width Modulation (SPWM), Space Vector Pulse Width Modulation (SVPWM) and also the basic Pulse Width Modulation (PWM) for DC motors. The fundamentals of applied modulation algorithms have been discussed and basic equations have been shown. The developed motor controller has been used to power three different types of motors, single-phase induction motor, threephase induction motor and magnetoelectric DC motor. The results of the conducted research have been reported in this work.
