Abstract: The three-dimensional magnetic circuit characteristics of the hybrid excitation motor,it is very inconvenient and time-consuming to analyze its transient and dynamic performance using traditional three-dimensional finite element software. This paper is based on the state space equation and the theory of the state space equation, combineds with the common coordinate transformation in the motor field,establishes the mathematical model of a twelve-phase hybrid excitation generator. A constant speed generator system model is designed in Simulink,and the operating characteristics of the hybrid excitation generator are analyzed. This method can accelerate the speed of motor analysis,and this model lays the foundation for the subsequent research on the control strategy of this type of motor.
