Abstract
The generator comprises rotor assembly composed of pole shoe, Nd-Fe-B permanent magnet, rotor iron core and rotor shaft, and stator assembly composed of stator iron core, coil, front-end cover and back-end cover. Characters are that Nd-Fe-B permanent magnets through pole shoes are fixed on the rotor iron core by non-magnetic conductive screw. Polarities of adjacent Nd-Fe-B permanent magnets are in opposition so as to form alternant arrangement between N pole and S pole. Each Nd-Fe-B permanent magnet in rotor corresponding to four poles in stator iron core so as to constitute Nd-Fe-B permanent magnet generator in four phases. Advantages are: low frequency, less number of turns in coil in each phase, small imaginary wastage, large effective output, small space etc. suitable to supplying DC power source.
