摘要：

The ripple losses in the ungrooved and grooved solid rotors of synchronous machines are analyzed on the basis of a new equivalent circuit model and calculation by the finite element method. Test results for these losses in 23. 4 MVA, 4 poles, 1500 rpm synchronous generator are compared with those analytically obtained using this method. The loss reduction due to the grooving can be estimated by this method with a satisfactory accuracy.
