Abstract

The invention provides an AC power generator comprising a body, a rotating shaft, circularly-annular stators, and rotors. The body is formed by assembling a housing, a front end cover, and a rear end cover. The rotating shaft passes through the front end cover and the rear end cover through a bearing. The stators are installed on the inner wall of the housing at intervals and comprise multiple coils. The coils and iron-free coil seats are formed by die casting and the coils are connected through connecting lines. The rotating shaft passes through the rotors. The rotors and the stator are successively arranged alternately. The rotor comprises a pedestal and multiple permanent magnets installed on both sides of the pedestal and having different polarities. The permanent magnets between adjacent rotors have different polarities. When the rotating shaft is driven to rotate, the coils of the stators cut magnetic lines formed by the rotors so as to generate electromotive force. Compared with a conventional AC power generator, the AC power generator is decreased in size and weight by multiple times, simpler in structure, easier to install and uninstall, greatly increased in power generation efficiency, low in running torque, low in driving rotating speed, and higher in energy efficiency.

Description

Technical field [0001] The invention relates to the field of generators, in particular to an AC generator. Background technique [0002] Alternator is an electromechanical device that converts mechanical energy into electrical energy in AC form. The alternator may include a stationary armature or stator, and the stationary armature or stator may include a set of stationary conductors (also referred to as "stator windings" or "conductive coils") wound in coils. The alternator may also include a rotating armature or rotor, which may be positioned in the stator or in a constant magnetic field. In some alternators, the constant magnetic field can be formed by permanent magnets. The rotating armature or rotor can be driven, rotated or rotated by an internal combustion engine. [0003] The armature or rotor of a traditional alternator mostly uses a silicon steel core, which is operated by electric excitation. Each turn of the stator coil needs to be embedded in the silicon steel wire...
