VARIABLE SPEED THRE-PHASE ALTERNATOR WITH TOROIDAL IRON CORE AND PERMANENT MAGNET

摘要

PURPOSE: A variable speed three-phase alternator with toroidal iron core and a permanent magnet are provided to obtain maximum power even in case that the speed of wind is low or high without a speed increasing unit. CONSTITUTION: A fixing unit is comprised of a circular iron core(201), an insulation demarcation strip(202), an electrical phase circular winding, a fixed disc, and a bearing house(205). The circular iron core has no slot. The fixed disc is combined in the inner circumference of the circular winding. The fixed disc is screwed in a bearing house. A rotator(100) is comprised of a rotating electrode plate(102), a rotating cylinder, a vertical axis, and a multiple bearing. A frequency comparator outputs an on-off value. An output control is comprised of a Y-delta switch.
