The "MJG-282IA" is a generator developed for small wind power generation, achieving a more compact and lightweight design compared to our conventional products. Due to its coreless design, there is no heat generation from eddy current losses, and the rotational torque of the shaft is low, making it easy to start rotating and capable of generating power from low torque. Additionally, it features a three-phase AC power output specification, which converts the output to DC using bridge rectification and then transforms it into stable single-phase AC 100V for use with general electrical products. 【Features】 ■ Compact ■ Small hydropower generation output up to 500W ■ Coreless ■ Three-phase AC power output specification *For more details, please refer to the catalog or feel free to contact us.
