• Inductor Coil

The "SKY-HR450W" is a highly efficient generator that achieves a high magnetic field through the use of rare earth magnets and a multipole structure, generating a high output voltage even at low rotational speeds (below 300 rpm). By adopting a rotating field excitation type where the magnet part rotates and a coreless structure that does not use an iron core, it has the advantage of having no electrical contact points, resulting in no cogging torque or iron losses. These features contribute to a smooth start and make it a highly efficient and reliable generator. This product is specially designed and manufactured for small wind power generation. 【Features】 ■ High output and efficient power generation system ■ Uses rare earth magnets ■ Specially designed and manufactured for small wind power generation ■ Coreless structure ■ No cogging torque or iron losses *For more details, please refer to the catalog or feel free to contact us.
