[Abstract]:The permanent magnet synchronous motor (PMSM) has the problem that the excitation magnetic field can not be adjusted, while the traditional medium and small-sized electroexcitation synchronous motor has the problem of brush slip ring. In this paper, a new brushless harmonic excitation synchronous motor based on open winding is proposed. The new principle motor can not only easily adjust the excitation but also remove the sliding ring brush, which has important academic significance and application value. In this paper, a systematic study of brushless harmonic excitation synchronous motor based on open winding is carried out, including the analysis of harmonic excitation principle, the influence factors of harmonic excitation performance, and the effect of current pulsation of excitation winding. The influence of tooth harmonic magnetic field, stator current control strategy, system simulation and experimental research. Firstly, the principle of harmonic excitation is analyzed. Through the theoretical analysis of the armature magnetic field in the motor, the mechanism of the induction electromotive force of the harmonic winding is expounded, and the new excitation principle is verified by finite element analysis. It lays a theoretical foundation for further research. Then the structure of the motor which is suitable for the harmonic excitation principle is studied. Based on the structural design of the traditional electrically excited synchronous motor, the harmonic excitation synchronous motor is obtained. The factors affecting the harmonic excitation performance, such as the number of turns of harmonic windings, the coefficient of polar arc and the thickness of pole boots, are analyzed and studied. The fluctuation of excitation winding current in steady state is studied, and the influence of filter capacitance on excitation current is analyzed. The influence of the tooth harmonic magnetic field and the high harmonic magnetic field in the motor is analyzed theoretically and the finite element analysis is carried out. Finally, the structure of the motor is optimized to make it more suitable for the operation of the harmonic excitation principle. According to the special requirement of harmonic excitation principle to stator current, a modulation strategy of third harmonic injection based on intermediate vector hexagonal SVPWM modulation of dual power converter is proposed, and the third harmonic current of stator is controlled by proportional resonance. The mutual decoupling control of the third harmonic current and the fundamental current of the stator and the non-static difference control of the third harmonic current are realized. The MATLAB simulation model of harmonic excitation synchronous motor and its control system is established on the basis of theoretical analysis. The simulation results verify the correctness of the mathematical model and the effectiveness of the control strategy. Finally, the prototype of brushless harmonic excitation synchronous motor is made, and the hardware experimental platform of its control system is built. The principle of harmonic excitation and the power conversion and excitation regulation of the motor are analyzed experimentally. Compared with the theoretical derivation and simulation results, the experimental results verify the correctness of the harmonic excitation principle and the effectiveness of the proposed control strategy. At the same time, the feasibility of the new principle motor scheme is verified.
