Abstract

A single-phase separately-excited magneto-resistive power generator comprises a stator, a rotor, excitation windings and an armature winding and is of a doubly-salient structure. Salients are arranged on the stator and the rotor. The number of the salients on the stator and the number of the salients on the rotor are the same and are even. The excitation windings are wound on the salients of the stator in a centralized mode, and winding coils on the adjacent salients are connected in series to form a one-phase excitation winding. The excitation windings on the adjacent salients of the stator are opposite in winding direction so that magnetic poles with alternative N poles and S poles can be formed on the adjacent salients of the stator. The armature winding is wound in a centralized mode, the winding coils on the adjacent salients are connected in series, and the armature winding can be wound on the salients of the stator and can also be wound on the salients of the rotor. The rotor of the power generator can be an outer rotor to form an outer rotor structure power generator, and can also be an inner rotor to form an inner rotor structure power generator.
