Abstract:
1. A multiphase electricity generator for a lighting tower, the multiphase generator comprising: n phases, n being an even integer, wherein each phase of the n phases is independent in a magnetic circuit that is common to all of the phases of the n phases and where each phase of the n phases is configured to power one lamp of a power greater than 750 W associated with the lighting tower; a rotor comprising permanent magnets providing 3 n poles; and a stator concentric with the rotor and subjected to a radial magnetic flux from the permanent magnets, the stator comprising a stack of laminations of silicon iron, each lamination of the stack of laminations having a silicon content greater than 0.5 percent and a thickness greater than 0.35 mm, the stack of laminations defining 4 n teeth, wherein every other tooth of the 4 n teeth carries a winding.
