First, let's take a look at the advantages of servo motors compared to other motors (such as stepper motors):
1. Accuracy: closed-loop control of position, speed and torque is realized; the problem of stepper motor out-of-step is overcome;
2. Speed: good high-speed performance, generally rated speed can reach 2000 ~ 3000 rpm;
3. Adaptability: strong anti-overload capability, able to withstand loads three times the rated torque, especially suitable for occasions with instantaneous load fluctuations and fast start requirements;
4. Stable: The low-speed operation is stable, and the stepping operation phenomenon similar to the stepping motor will not occur during low-speed operation. Applicable to occasions with high-speed response requirements;
5. Timeliness: The dynamic response time of motor acceleration and deceleration is short, generally within tens of milliseconds;
6. Comfort: heat and noise are significantly reduced.
To put it simply: the ordinary motor that is usually seen will rotate for a while due to its own inertia after the power is turned off, and then stop. The servo motor and the stepper motor are to stop when they say they stop, and they can go when they say they are going, and the response is extremely fast. But the stepper motor is out of step.
There are too many applications for servo motors. Servo motors may generally be involved as long as there is a power source and requirements for accuracy. Such as machine tools, printing equipment, packaging equipment, textile equipment, laser processing equipment, robots, automated production lines and other equipment that require relatively high process accuracy, processing efficiency and work reliability.
