Properties of Adjust Magnetic Field of Hybrid Excitation Synchronous Machine With Tangential Accumulation of Magnetic Field Shunt-wound Magnetic Path

To solve the existing hybrid excitation machine problems, such as the difficulty of total adjustment of air gap magnetic field, many additional magnetic circuits, and considerable additional air gap, etc. According to the structural characteristics and the principle of magnetic regulation of HESM with the tangential accumulation of magnetic field shunt-wound magnetic path. With Ansys Maxwell finite element simulation software, the influence of the magnetic potential of the electric excitation on the working point of the permanent magnet is analyzed. The variation law of the magnetic field of the motor under different excitation conditions is studied. The results show that due to the characteristics of the parallel magnetic path, the magnetic accumulation effect of the machine is pronounced, and the fault tolerance performance of the motor is good. The main magnetic field can be adjusted entirely and controlled.
