| Abstract: | The Unbalanced Magnetic Pull (UMP) caused by eccentricity between stator and rotor in hydroelectric generator is studied in this paper where according to basic concept of magnetic pull and the characteristic of UMP an approximate formula to calculate UMP is presented Calculation results show its validity and convenience in using. Good agreement is achieved by comparing the results with those of FEM. The formula presented here can be offered to the designing and analyzing of vabrition. |
