A direct torque control for a PMSM

Abstract

For a long time, permanent magnet synchronous motors (PMSM) were only applied in some particular fields, e.g. for servo drives. However, in recent years PMSM gained increasing importance in novel domains like automotive hybrid drive trains. For Mexico, this boom represents a valuable opportunity for universities and research institutions, so that together with Mexican industry of the Electric Vehicle (EV) forming partnerships that result in an infrastructure that will enable the country to develop its own technology in terms of EV. This paper presents a competent and not complex direct torque controller (DTC) for PMSM drives.
