How to choose a suitable linear motor module to maintain the stability and efficiency of the equipment.

Selection elements of linear motor:

1. The amount of exercise load, the maximum load that can be borne (with a safety margin of 80%), and the deviation of the center of gravity during operation.

2. The installation method of linear motors, horizontal installation is the best way under the same conditions, only requiring customer service friction to minimize thrust loss. The thrust used for side mounted, inverted, vertical, and other applications is higher than that for horizontal installation.

3. The effective distance for the operation of a linear motor depends on whether it adopts a single actuator, double actuator, or multi slider operation mode.

4. The running trajectory of a linear motor, whether it is point-to-point linear motion or trajectory motion.

5. The movement time and pause time of point-to-point motion; The speed and acceleration of trajectory motion.

6. The precision requirements of linear motors include different precision and repeated supplementary precision, whether a grating ruler or a magnetic grating ruler is used.

7. Considering the operating environment, whether it is stable, humid, dusty, etc.

8. Other supplements, such as drag chain, Hall, and driver brand selection.

No matter what operating mode is used, selecting the right type of linear motor is the most economical mode. Without running on the machine, the actual load and speed cannot be carried, and the cost of modifying the module stroke and thrust values is very high.

The selection elements of the flat linear motor module include the following aspects:
1. Power output requirements: Considering the working environment and workload of the application, it is necessary to determine the required output power and torque, and select an appropriate motor.
2. Motion control requirements: Select a control scheme, including speed control, position control, acceleration control, etc. Meanwhile, it is necessary to select appropriate encoders and sensors according to different application scenarios.
3. Noise and vibration: For applications that require maintaining silence or reducing vibration, it is necessary to choose motors with low noise and low vibration.
4. Other special requirements: For applications in special environments such as high temperature resistance and waterproofing, motors with corresponding characteristics need to be selected.
5. Cost and reliability: Based on budget and reliability requirements, evaluate the price and performance of optional motors and select the best balance point.

It is necessary to consider the above factors comprehensively and choose a flat linear motor module that is suitable for specific applications.
