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