Tips: Why servo motor matches with a gearbox?

The servo planetary gearbox is needed when the load must be moved under precision position requirement. Generally, the equipment involved are automation equipment, such as aviation, satellite, medical, military technology, wafer equipment, robots. The common characteristic for them is that the torque required to move the load generally far exceeds the torque capacity of the servo motor itself. Using a gear reducer to improve the output torque of the servo motor can effectively solve this problem.

Output torque can be increased by directly increasing output torque of the servo motor, however, such a mode not only requires an expensive high power servo motor, the motor shall also have stronger structures. The increase of torque is proportional to the increase of control current, if a larger driver is used, the increase of specifications of power electronic components and related electromechanical equipment will greatly increase the cost of the control system.
