The paper presents an approach to simulation analysis of synchronous reluctance motor transients by means of indirect field-circuit method. Dynamic performance of two pole synchronous reluctance motor with axially laminated, anisotropic rotor with modified magnetic circuit was investigated. Asymmetrical equivalent rotor damping cage and skin effects in aluminum layers were taking into account. An indirect field-circuit model including frequency dependent parameters of damping circuit was derived and implemented in Matlab/Simulink environment. A series of simulation were performed for different start up parameters (initial voltage, initial frequency, start-up duration), shaft torque step and moment of inertia. The simulation results confirmed good dynamic performance of the motor with modified rotor structure and the reliability of proposed simulation method, although some improvements are still necessary.
