NEW DEVELOPMENT OF TORQUE ANALYSIS OF SYNCHRONOUS MACHINE

By using a multi-loop model, a new technique for analysing the torque of a synchronous machine is presented in this paper. The electro-magne tic torque of the machine which is very difficult to calculate in some operation conditions by other methods, can be obtained from the induc tances of the machine and the currents of every loop of the machine, t hen the average torque and the pulse torque by Fast Fourier Technique. Comparing the results obtained by the new technique with an establish ed method, the new method is justified.
