摘要：

Solid rotors can be adapted to synchronous motors of 5 MW and over in applications with high inertia loads. The eddy currents induced in the solid pole are used for starting of the motor and their paths are changed depending on the design of the rotor shape unlike the synchronous motors with damper windings or cages. In this paper, the starting characteristic of a 7 MW solid salient pole synchronous motor is analyzed by the combined methods for two and three-dimensional finite element models because a three-dimensional analysis to solve the problem is difficult due to the long solving time. The maximum difference between results of the combined method for two and three-dimensional finite element analysis and the factory test is less than 10%.
