摘要

The hub generator (10) has an axle (80) with two ends, a middle and two outer threads (82), having a diameter whereby outer threads are made around the axle, at each end of the axle. A middle thread having a diameter, is made around the axle between the outer threads. A hollow hub (20) which is rotatable is mounted on the axle and the hub has a chamber (21) on two sides. A ring shaped recess (22) is formed in the chamber at one side of the hub and is connected with the chamber. A hub hole (23) is formed coaxially in the other side of the hub, at the opposite side of the ring shaped recess and is connected with the chamber. A stator (30) which can rotate in the chamber of the hub, is mounted at the middle of the axle.
