| Abstract |
The additional losses of a DC motor fed from an asymmetrical single phase bridge can be determined by an equivalent resistance which is calculated by the polynomial approximation based on experimental data. It has been shown that very limitted number of experimental data qives very good approximation. The results obtained by this method give better accuracy then any other method known to the authors. The method makes the calculations very simple. It does not depend on the agreement between frequencies of the parameters and frequencies of armature current ripple. The higher accuracy is achieved in the case when frequencies of measured parameters respond to frequencies of main line current ripple. |
