Let’s first take a look at what advantages servo motors have over other types of motors (such as stepper motors):
1. Precision: It achieves closed-loop control of position, speed, and torque; it overcomes the problem of step loss in stepper motors;
2. Speed: It has excellent high-speed performance, with the general rated speed reaching 2000 to 3000 revolutions per minute;
3. Adaptability: It has strong overload resistance and can withstand three times the rated torque, making it particularly suitable for occasions with sudden load fluctuations and requirements for rapid startup;
4. Stability: It runs smoothly at low speeds, and does not exhibit the step-like operation phenomenon similar to stepper motors at low speeds. It is suitable for applications requiring high-speed response;
5. Timeliness: The dynamic response time for acceleration and deceleration of the motor is short, generally within tens of milliseconds;
6. Comfort: Heat generation and noise are significantly reduced.
In simple terms: The ordinary motors you usually see will continue to rotate for a while after power loss due to their inertia, and then stop. However, servo motors and stepper motors stop and start immediately, with extremely fast responses. But stepper motors have the problem of step loss.
The application fields of servo motors are numerous. Any equipment that requires a power source and has precision requirements is likely to involve servo motors. Such as machine tools, printing equipment, packaging equipment, textile equipment, laser processing equipment, robots, automated production lines, etc., which have relatively high requirements for process accuracy, processing efficiency, and work reliability.
