| Abstract |
In this paper a numerical simulation of self-controlled current fed synchronous motors under transient operations is proposed. The combined electromagnetic and mechanical equations of the machine are solved through the operating equations of the inverter. The different inductances of the machine are calculated from the field distribution obtained from the finite element calculations. These inductances are introduced in the variable coefficient differential equations of the machine which are solved using step-by-step numerical integration. In the present study a current regulation in the D.C. loop is used for very low speeds with forced commutation during starting. An application on a 6.2 kVA permanent magnet motor is done and results are given in the paper. Starting and transient operations due to sudden perturbations are studied. |
