Abstract

The utility model mainly aims to provide an overlapping type axial double magnetic rare earth permanent magnet generator suitable for military use and civil use. The generator comprises a plurality of stators, a plurality of one-side rotors and two-side rotors, and a housing. Each stator comprises an iron core, a clamp sheet, a winding and a chuck. Compared with the conventional generator, the iron cores are small in size, convenient in processing and energy-saving in the processing process with a utilization rate reaching 100%. The winding is small in size, and simple in processing. The clamp sheets and the chucks are common machining elements. Each rotor comprises a magnetic pallet and magnetic steel. Each two-side rotor comprises a magnetic pallet, whose two surfaces are pasted by magnetic steel. The magnetic pallets are designed to achieve functions of a flywheel and a fan apart from magnetic steel adhesion, and to change the combination form from the conventional axial generator of rotor-stator-rotor to a combination form of rotor-stator-two-side rotor-stator-rotor, so as to allow two or more stators to be overlapped for superposition of power, and effectively utilize axial space and reduce radial space.
