Abstract
Abstract The electric vehicle drive is nowadays considerably widespread in everyday road transport. These vehicles have an important component: the electric motor. The motors are tested using a simulation program for which knowledge of its electromagnetic and dynamic parameters are needed. These data are usually not provided by the manufacturers; therefore, it must be determined experimentally by measurements. For this purpose, at the Faculty of Engineering of the University of Debrecen there is the structure of a complex measuring system in progress. With this system, we can determine the motor parameters required for the simulation for all electric motors used in the automotive industry. In this publication, we will present a method designed to produce one of the characteristic electromagnetic parameters of electric motors; the variable frequency and strength sinusoidal alternating current required to determine the inductance of windings.
