The origin of this name servo motor for injection molding machine is mainly due to the key role of its core drive system – the servo motor in the injection molding process.
A servo motor is a motor that can achieve high-precision control. It uses a closed-loop control system (i.e., motor + sensor + controller) to accurately control the angular displacement, speed, and acceleration of mechanical motion. In our injection molding machines, servo motors are used to drive key components such as the injection screw and mold closing mechanism to accurately control the entire plastic product injection process.
Why called servo motor for injection molding machine has characteristics of high precision, high efficiency, and fast response.
Injection molding machine servo motors are closed-loop control systems that precisely control the speed and position of the motor through a feedback mechanism to achieve precise control of the injection molding machine.
This kind of motor can achieve precise speed and pressure control by changing the speed and torque of the servo motor according to the command signal from the computer.
For example, servomotors can significantly reduce energy consumption, increase productivity, and allow for fast response times.
Resulting in reduced downtime and improved product quality.
In addition, servomotors have automatic voltage regulation.
Which effectively manages voltage fluctuations to ensure the stability and reliability of the servo motor injection molding machine process.
Therefore, servo motors are called servo motors because they achieve precise control of the injection molding machine through a closed-loop control system, thus improving productivity and product quality.
