Fan hub power supply equipment

The invention relates to fan hub power supply equipment, and effectively solves the problems that existing hub power supply equipment of a wind generating set is high in use cost and poor in stability and reliability. According to the technical scheme, a power shaft is coaxially arranged in a mounting cylinder and driven by a motor arranged outside the mounting cylinder, a permanent magnet rotor is arranged on the power shaft, and a stator winding matched with the permanent magnet rotor is arranged on the inner wall of the mounting cylinder; the side, away from the motor, of the installation cylinder is fixedly installed on the hub shaft through a flange assembly, and liquid cooling assemblies are arranged in the installation cylinder located on the two sides of the stator winding. According to the scheme, power can be supplied to the hub side from the cabin side of the wind generating set under the condition of no abrasion, the maintenance cost is reduced, and meanwhile the operation reliability of equipment
