Abstract
A generator rotor structure comprises a cylinder body, at least a magnetic member, and a shaft. A penetrating bore is adapted at the center of the cylinder body. A plurality of containing spaces is adapted between the sidewall of the penetrating bore and the outer sidewall of the cylinder body. The adjacent containing spaces include a connecting part. The shaft passes through the penetrating bore, and the magnetic member is adapted on the outer sidewall of the cylinder body. The present invention can also be implemented according to another embodiment of the present invention, which comprises a hollow body, at least a connecting part, at least a shaft sleeve, at least a magnetic member, and a shaft. The connecting part is connected on the inner sidewall of the hollow body, and the shaft sleeve is connected to the connecting part. In addition, the shaft passes through the shaft sleeve, and the magnetic member is adapted on the outer sidewall of the hollow body. Thereby the power generated by the generator can be enhanced. Moreover, owing to reduced weight and moment of inertia of the rotor, the power generated by the generator can be increased at low wind speeds.
