Inner rotor cooling type high-power eddy speed regulator

The invention discloses an inner rotor cooling type high-power eddy speed regulator. The inner rotor cooling type high-power eddy speed regulator comprises an inner rotor, an outer rotor and a cooling liquid feeding and discharging system, wherein the inner rotor comprises an inner rotor shaft, an inner rotor rotating disk and two symmetric electroconductive metal disks, the cooling liquid feeding and discharging system comprises a cooling liquid feeding and discharging pipeline, a cooling liquid collector and an outer heat exchange mechanism, and the outer rotor comprises an outer rotor shaft, two symmetric magnetic outer rotor moving disks and a rotary linear adjusting mechanism. The cooling liquid feeding and discharging pipeline is arranged inside the inner rotor shaft and the inner rotor rotating disk. A changeable air gap is reserved between each outer rotor moving disk and the electroconductive metal disk which are arranged on the same side. After the structure is adopted, the inner rotor is in flexible (magnetic) connection with the outer rotor and is simple in structure, low in processing difficulty and beneficial to assembly and maintenance. The cooling liquid feeding and discharging system is capable of cooling the inner rotor rotating disk maximally and subjecting the outer rotor permanent magnet disks to air convection cooling, so that high-power eddy speed regulation is achieved.
