Disclosed is a brushless double-fed wind power generator. Numbers of pole pairs of a power winding and a control winding of a stator are respectively pp and pc, a mixed rotor is positioned in the stator and provided with pp+pc salient poles, each salient pole is provided with a plurality of slits, leads are disposed in the slits, and the ends of the inner leads in adjacent slits are shorted to form a concentric coil. The brushless double-fed wind power generator is in a mixed rotor novel structure combining traditional magnetic resistance with cage type rotor, and is more superior in performance than those of the traditional reluctance rotor and the cage type rotor. A torque control scheme is directly used in an excitation control means, while the speed sensorless control technique is adopted, so that the brushless double-fed wind power generator is more applicable to severe wind fields, and has fine highest power tracking and response capacity.
