What Is Servo Motor

Servo motors are divided into two categories: DC and AC servo motors. The main feature is that there is no rotation when the signal voltage is zero, and the speed decreases at a uniform speed with the increase of torque. The motor is an electronic product that uses the principle of electromagnetic, and the energized coil generates a force to rotate in the magnetic field environment.

Regarding servos, servo drives, servo motors, and servo systems, many people don’t have a clear understanding of it. Even those who work with servos, most of them have a ‘semi-knowledge’ of servos. If I really understand it deeply, I still can't feel it.

So what is a servo?

In fact, servo is a term in terms of performance. Generally, it can be called servo as long as the approximation between the master command and the control result reaches a certain height, which has no direct relationship with the structure of the machine. This is to precisely control the motor, and a system such as "servo" has been specially developed. In fact, the servo system is not necessarily a motor system, and some pneumatic systems are also called pneumatic servos.

The servo system is mainly composed of upper computer, servo amplifier, motor, driver, command mechanism and other parts. Host computer: Give servo instructions. Servo amplifier: receives and processes instructions from the host computer, and controls the rotation angle and speed of the motor. The servo motor is the actuator. (The encoder that comes with the servo motor feeds back the angle and speed of the motor's rotation to the servo amplifier to form a closed loop to ensure accuracy.) The driver is the power source of the motor, and the command mechanism is to send pulses or give speed Servo drive.

Many people may find it strange to see this. Why do you want to make such a complicated system? Isn't this just controlling a motor? In fact, it is necessary to introduce some information such as motor application, principle and development. In the early days of mankind, many motor varieties and categories were designed. They existed for a long time due to their respective advantages, but their inherent shortcomings have gradually been unable to meet the needs of mankind.

Servo motors are divided into two categories: DC and AC servo motors. The main feature is that there is no rotation when the signal voltage is zero, and the speed decreases at a uniform speed with the increase of torque. The motor is an electronic product that uses the principle of electromagnetic, and the energized coil generates a force to rotate in the magnetic field environment. Servo is a further product developed on the technology of frequency conversion. It uses encoder feedback information on the motor butt, and the internal CPU of the driver combines this feedback information to generate pulses for controlling the three-phase current output, thereby realizing precise control of the servo motor. .

Regarding the above too professional terms, the layman may not understand it, and the insider seems to understand the terminology. In fact, the servo system is very simple. Take a chestnut: the boss of a team says to the following people "what information do I want", "what report do I want" and so on. The following people calculate according to all the internal information methods of the company. Get the answer that the boss needs. The servo system is such a system.
