Numerical Calculation of End Leakage Reactance of Submersible Motor

Three-dimensional finite element mathematic model which takes into account adequately the influence of stator magnetic isolated segment and rotor supporting bearing used to calculate end leakage reactance is established for the especial structure of submersible motor in this paper. The calculation result of this paper is closer to the test data compared with traditional calculation method and the design accuracy is improved effectively. The end leakage reactance curve group of submersible motor which are provided with prevalent applied worthiness is acquired on this groundwork. The curve group offers basis to improve the submersible motor design and possesses important engineering meaning.
