First of all, let us know what torque is, the engine is the torque of the servo motor, which refers to the torque that the engine outputs 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 a certain range. On the other hand, the external torque is called the torque or the external force moment, and the internal internal torque is called the torque or the torque.
The torque control mode is to set the external output torque of the motor shaft through the input of the external analog quantity or the assignment of the direct address. Specifically, for example, if 10V corresponds to 5Nm, when the external analog quantity is set to 5V, the motor The shaft output is 2.5 Nm. If the motor shaft load is lower than 2.5Nm, the motor will rotate forward. When the external load is equal to 2.5Nm, the motor will not rotate. When the motor is larger than 2.5Nm, the motor will reverse (usually under the condition of gravity load).
We can also change the set torque by changing the setting of the analog quantity in real time, or by changing the value of the corresponding address by communication. Its application is mainly in the winding and unwinding devices that have strict requirements on the material stress, such as the wire device or the fiber-optic device. The torque setting is changed according to the change of the radius of the winding to ensure the material is affected. The force does not change as the winding radius changes.
