THE PERMANENT MAGNET GENERATOR WITH ELECTRIC FIELD BRIDGE

摘要

A permanent magnet generator with electric field bridge, whose permanent magnet flux of each pole is branched by the magnetic bridge, which is arranged between two adjoining poles. Power supply feed power to the field coil which wind around the magnetic bridge. During adjusting the power supply current, the field strength and the air gap magnetic flux are altered, thereby the generator voltage is changed. During adjusting the frequency of the variable swing field current, the generator winding frequency is altered, thereby the frequency voltage is changed. The invention has advantage of simple, convenience and adjusting generator voltage, stabilizing voltage and variating frequency economically.
