Abstract

The magnetic field of turbo-generator end-windings is analysed. Particular attention is given to the field at the surface of the statorcore end-plate. The effects of varying the cone angle of the endwinding, the chording angle and the length of the axial portion of the end-winding are discussed. The effect of power factor is considered with particular reference to the large fields observed at leading power factors. Experimental results on a model winding show reasonable agreement with the computed results.
