Abstract:
1. A drive system, comprising: a motor unit, including a load rotation part revolvingly supported by a bearing; first and second transmissions having different speed ratios and being respectively provided between the load rotation part and the motor main shaft, and the load rotation part and the auxiliary shaft, to jointly drive the load rotation part, the first transmission being connected to the motor main shaft to drive the load rotation part to thus form a first power train, while the second transmission being connected to the auxiliary shaft to drive the load rotation part to thus form a second power train; and two one-way transmission units respectively provided between the load rotation part and the first transmission, and between the load rotation part and the second transmission, so to transmit revolving power from the motor main shaft or the auxiliary shaft to the load rotation part, and which prevent the motor main shaft or the auxiliary shaft from receiving an inverse transmission force from a direction of the load rotation part.
