Abstract :
This paper evaluates the effects of using zero voltage vectors in DTC (Direct Torque Control) applications. The evaluation considers a DTC-driven field wound synchronous motor, where the analysis is carried out using a combination of analytical and FEM (Finite Element Method) simulations. The simulations are assessed against a background of measurement results. The main emphasis of the analysis is placed on finding the losses in the motor, with a particular focus on those occurring in the solid rotor pole-plates. The paper will also utilise an innovative power difference method to estimate the time harmonic power losses in the machine.
