Analysis on how servo motor controls torque

Many people may have heard of engines, but not everyone may know about servo motors. In fact, mechanical equipment is inseparable from engines. Only with engines can these mechanical equipment operate normally.

And because servo motors have their own advantages, they are widely used in various fields. It can be seen that this motor is a very important existence. What the editor wants to share with you today is an analysis of how servo motors control torque.

The analysis on how the servo motor controls torque is as follows:

First, let’s understand what torque is. The torque of the engine, that is, the servo motor, refers to the torque output by the engine from the crankshaft end. Under the condition of fixed power, it is inversely proportional to the engine speed. The faster the speed, the smaller the torque, and vice versa. It reflects its load capacity within the range.

On the other hand, the external torque is called torque or external couple moment, and the internal torque is called internal couple moment or torque.

The torque control method is to set the external output torque of the motor shaft through external analog input or direct address assignment. For example, if 10V corresponds to 5Nm, when the external analog is set to 5V, the motor Shaft output is 2.5Nm.

If the motor shaft load is less than 2.5Nm, the motor rotates forward. When the external load is equal to 2.5Nm, the motor does not rotate. When the external load is greater than 2.5Nm, the motor rotates reversely (usually occurs when there is a gravity load).

We can also change the set torque by changing the analog setting in real time, or by changing the value of the corresponding address through communication. Its application is mainly in winding and unwinding devices that have strict requirements on the force of the material, such as wire-rapping devices or fiber-pulling equipment. The setting of the torque should be changed at any time according to the change of the winding radius to ensure that the material is stressed. The force does not change as the winding radius changes.

Regarding how servo motors control torque, the editor will share it here. Now everyone should have a general understanding of how servo motors control torque, right? I hope the above content can help everyone!
