The analysis and design of electromechanic devices involve the solution of large sparse linear systems, and require, therefore, high performance algorithms. In this paper, the Schur complement method with a parallel preconditioned conjugate gradient (PCG) solver is introduced into two-dimensional parallel time-stepping finite element formulation to analyze a rotating machine considering an electromagnetic field, external circuit and rotor movement. The proposed parallel solver with two preconditioners is analyzed concerning its computational efficiency and number of iterations. The results of the simulation of a rotating machine are also presented.
