GENERATOR WITH TOROID TYPE STATOR

摘要

PURPOSE: A generator having toroid type stator is provided to reduce magnetic flux resistance between rotary permanent magnet and magnetic core member, thereby increasing generation efficiency. CONSTITUTION: A fluid sealed body (120) injects ferrofluid (110) into inside. Coil is wound in around the fluid sealed body in a toroid type. Multiple permanent magnets (241,242) are circularly arranged in the outside of the coil. A rotor fixes the multiple permanent magnets to a rotation axis. The ferrofluid comprises liquid ferromagnetic material.
