Abstract :
This paper presents a study of eddy current rotor losses in solid pole synchronous machines, fed by a voltage source inverter. The main emphasis is on DTC (direct torque control) application. The DTC operation loss analysis is carried out using FEM (finite element method)-software. The article considers a novel modelling technique that can be used when simulating inverter-fed machines in 2D- FEM application. In addition this article includes a brief introduction into how DTC operates.
