Problems solved by technology

Moreover, most of the existing multiphase reluctance generators adopt a 6 / 4 structure, and the number of salient poles on the stator and the number of salient poles on the rotor are not equal
The multi-phase reluctance generator has many phases, its stator connection is relatively complicated, and the system cost is high
Due to the existence of permanent magnets in permanent magnet generators, permanent magnet motors are not easy to be controlled, and permanent magnets have demagnetization phenomena. With severe mechanical vibration, irreversible demagnetization may occur, and the stability of the motor is low, which may even cause it to be unusable.

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.

Description

technical field [0001] The invention relates to a single-phase separately excited reluctance generator, which belongs to the field of reluctance motors. Background technique [0002] The traditional reluctance generator adopts a multi-phase structure, and each stator salient pole is wound with a concentrated excitation coil, and the excitation coils on two radially opposite stator salient poles are connected in series to form a stator winding of one phase, of which three Phase reluctance generators are the most common. Moreover, most existing multiphase reluctance generators adopt a 6 / 4 structure, and the number of salient poles on the stator and the number of salient poles on the rotor are not equal. The multi-phase reluctance generator has many phases, its stator connection is relatively complicated, and the system cost is high. Due to the existence of permanent magnets in permanent magnet generators, permanent magnet motors are not easy to be controlled, and permanent m...
