对主传动系统，我选用FANUC AC电动机通过带传动驱动主轴。

由于转动关节可以采用简单的轴承座支承，转动角的驱动主体部分可以放置于身体之上，通过传动驱动其转动。

Since the rotating joint is supported by the simple bearing, the main part of the rotation-angle control device can be replaced on the body and be driven to rotate.

你要找的是电磁体（螺线管），在传动机构中驱动第一齿轮。

What you're looking for is the electromagnet (solenoid). which turns the first gear in the gear train.
