What is the difference between a servo motor and a linear motor? Servo manufacturers answer for you: servo motors VS linear motors.
What is the difference between a servo motor and a linear motor?
Many equipment in the operation process will use the motor to drive, at this time it is useful to be linear motor and servo motor, then what is the difference between linear motor and servo motor, let’s follow us to briefly understand.

1. Servo motor generally refers to the engine that controls the operation of the mechanical components of the servo system, and is an indirect speed change device that subsidizes the motor; The servo motor can make the control speed and position accuracy very accurate, can convert the voltage signal into torque and speed, drive the control object and closed-loop control.
2. Linear motor has compact structure, small power loss, fast moving speed, high acceleration and high speed (linear motor can realize high-precision position positioning control from high speed to low speed; Metro automatic gates.

3. Linear motor is a kind of transmission device, which directly converts electrical energy into linear motion mechanical energy, without any intermediate conversion mechanism; It can be seen as a rotating motor, the side that evolves from the stator is called the primary, the side that evolves from the rotor is called the primary, and the side where the rotor evolves is called the secondary; In practical applications, primary and secondary are manufactured to different lengths to ensure that the coupling between primary and secondary remains constant over the required travel range; Linear motors can be short primary, long secondary or long primary and short secondary.

Considering the manufacturing cost and operating cost, short primary and long secondary are generally used.
Through the above brief introduction, I have a preliminary understanding of the choice of linear motors and servo motors.
Servo motor Vs linear motor
What is the difference between a servo motor and a linear motor? difference between servo motor and stepper motor.
Linear motor, also known as linear motor and linear motor, is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism.
The difference between servo motor module and linear motor: Servo motor module and linear motor are both different and related. They are all automatic transmission elements, capable of linear movement, all of which are assembled on aluminum profiles and covered with plates, and look similar in appearance.

difference between servo motor and linear motor
1. The difference between the principle of linear motion
Although the appearance is similar, the principle of linear motion is different, linear motor is electrical energy directly converted into mechanical energy, without the need for intermediate mechanisms to achieve linear motion, while servo motor module needs to use ball screw or timing belt to convert curved motion into linear motion.

2. The difference in accuracy
Linear motor than servo motor module precision is higher, linear motor structure is simple, do not need to go through the intermediate conversion mechanism and directly produce linear motion, motion inertia is reduced, dynamic response performance and positioning accuracy are greatly improved, linear motor accuracy can reach micron level or even sub-micron level, and servo motor module accuracy is generally around a few wires.
3. The difference in speed
In terms of speed, linear motors have considerable advantages, and the speed of linear motors will be further improved after successfully solving the heating problem, while “rotary servo motor + ball screw” has been limited in speed and it is difficult to improve. In terms of dynamic response, linear motors have advantages due to their simpler and more compact mechanism.

In terms of speed control, the linear motor has a faster response and a wider speed regulation range, which can reach a higher speed at the moment of start-up and can be stopped quickly when running at high speed.
4. The difference between noise
Linear motors are less noisy than servo motor modules, because linear motors are not constrained by centrifugal force, and there is no mechanical contact during movement, so there is no friction and noise. There is no wear of the transmission parts, which can greatly reduce mechanical losses and avoid noise caused by towing cables, steel cables, gears and pulleys, etc., thereby improving the overall efficiency.
5. The difference in price
Linear motors have higher performance than servo motor modules in all aspects, so in terms of price, linear motors will be more expensive, usually several times more expensive.

Difference between linear motor and servo motor
About the difference between linear motor and servo motor, the difference between linear motor and servo motor This many people do not know, today Xiaoliu to answer the above questions for everyone, now let’s take a look together!

1, in fact, linear motor is also a kind of servo motor, in theory, as long as there is a feedback system (linear motor is usually feedback with Hall or linear grating) should be a servo system.
2. Therefore, servo motors should be broadly divided into two categories: rotary servo motors and linear servo motors.
3. Characteristics of linear motor: high dynamic characteristics, high rigidity.
4. Compared with the traditional linear transmission structure (such as lead screw, electric cylinder), it is maintenance-free, but the cost is higher.

5. It is mainly used for some occasions with very high dynamic characteristics of the system and special environments, such as semiconductor production lines.
6. Servo motor refers to the engine that controls the operation of mechanical components in the servo system, and is an indirect speed change device that supplements the motor.
7. The servo motor can control the speed, position accuracy is very accurate, can convert the voltage signal into torque and speed to drive the control object, closed-loop control.

8. Stepper motor: Stepper motor is an open-loop control element stepper motor that converts the electrical pulse signal into angular displacement or line displacement, and pulse-open-loop control.
9. Linear motor is also called linear motor, linear motor is a kind of transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism.

10. It can be seen as a rotating motor split radially and expanded into a plane to form a direct drive motor: the abbreviation of direct drive motor. It mainly means that the motor does not need to go through the transmission device (such as the drive belt, etc.) when driving the load.
