Abstract

[0002] Currently, mainstream photovoltaic (PV) tracking bracket drive systems are divided into vertical rotary drive systems and horizontal rotary drive systems. The entire system can only output motor power in one direction, thus failing to efficiently transmit motor torque.

Solving these problems requires suspending more adapters on the drive system, which not only negatively impacts system stability but also increases system costs.
[0003] Therefore, there is a need in this field for a drive device that is simple and practical in structure, easy to install and maintain, low in cost, reliable in quality, has high linkage transmission efficiency and high reliability, and can realize bidirectional output of motor power.
