1.Precision:

Closed-loop control of position, speed and torque is realized, eliminating the step loss problem of stepper motors.
2.Adaptability:

Strong overload resistance, capable of bearing loads up to three times the rated torque. It is especially suitable for applications with instantaneous load fluctuations and fast start requirements.
3.Responsiveness:

Short dynamic response time for acceleration and deceleration, typically within tens of milliseconds.
In short, ordinary motors continue to rotate due to inertia for a period of time after power is cut off before stopping. In contrast, servo motors and stepper motors start and stop immediately in response to signals, with extremely fast response. Since stepper motors suffer from step loss, which is well overcome by servo motors, servo motors are used in a wider range of applications.
Generally speaking, servo motors are used wherever a power source is required and high precision is demanded. Examples include machine tools, printing equipment, packaging machinery, textile equipment, laser processing equipment, robots, automated production lines, and other equipment with high requirements for processing accuracy, efficiency and reliability.
