Abstract：This paper presents a structure of self-resistance increase of rotor winding based on the principle of compound coil. By analyzing the prototype’s winding connecting mode of both stator and rotor, the function of the stator windings that designed by the principle of pole-changing winding is illustrated when the operating condition of the prototype switching from starting to running. The principle is described in detail that the autoresistive structure can effectively increase the rotor resistance of the prototype during starting, and the value of rotor resistance return to normal while running. The self-starting characteristics and asynchronous starting characteristics of the prototype with different load conditions are simulated and compared by finite element simulation and prototype test. The simulation and test results show that the brushless doubly-fed structure with self-resistive structure exceeds traditional brushless doubly-fed machine by overcoming the problems of large starting current and low torque. It has good starting characteristics that suitable for the occasions where frequent starting is required.
