Before answering this question, it is first important to understand the purpose of a servo motor. Unlike ordinary motors, servo motors are primarily used for precise positioning. Therefore, what people generally refer to as servo control is actually the position control of the servo motor. In fact, servo motors have two other operating modes: speed control and torque control, though these are less commonly applied. Speed control is typically achieved by a frequency converter. Using a servo motor for speed control is usually reserved for scenarios requiring rapid acceleration/deceleration or highly precise speed regulation. Compared with frequency converters, a…

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…
