Background technique

Some existing rotating devices have requirements for both communication and power transmission, such as rotating radars; in some rotating radars, due to the traditional wired power supply being limited by the power supply cable, 360° omnidirectional rotation cannot be achieved, but only To achieve rotation within a certain range, such as 270°, the radar needs to continuously run back and forth, and the corresponding motor needs to continuously accelerate and decelerate; in other rotating radars, in order to solve the rotation limitation of wired power supply, brushes or brushes are usually used.
