Benefiting from the effective combination of two excitation sources including the permanent magnet and field excitation, the hybrid excitation machine(HEM) has the advantages of the flexibly adjustable magnetic field, high power density, and high efficiency at wide speed range. It is a promising candidate in the applications of industrial drive, new energy power generation, and transportation. The structure features and flux regulation principles of two different types of HEMs, named hybrid excitation synchronous machine and hybrid excitation flux modulation machine, were overviewed. On this basis, the general design method and multi-dimensional coordinated control strategy of the HEMs for typical applications were presented. Under the background of transportation electrification, the state-of-art and prospects of the application of the HEMs in more-electric-aircrafts, electric ships, and electric vehicles were summarized. Finally, the key technology and further study direction of the HEMs were discussed.
