Precautions for servo motor operation

I have introduced the maintenance and precautions of servo motors before. Today I want to explain the precautions for operating servo motors. In recent years, with the improvement of people's quality of life, many things are required to be precise. Generally, servo motors are used in these places that require precision.

The servo motor can quickly determine some corresponding parameters, because this motor is a very precise device. Of course, there are some precautions when using it, as follows:

1. Protection of oil and water

1. The servo can be used in places that are affected by water or oil droplets, but it is not fully waterproof or oil-proof. Therefore, this motor should not be placed or used in water or oil-filled environments.

2. If the servo is connected to a reduction gear, an oil seal should be used when using it to prevent the oil from the reduction gear from entering the servo motor.

3. Do not immerse the servo cable in oil or water.

2. Cable → Reduce stress

1. Ensure that the cable is not subject to moment or vertical load due to external bending force or its own weight, especially at the cable exit or connection.

2. In the case of servo movement, the cable (that is, the one equipped with the motor) should be firmly fixed to a stationary part (relative to the motor), and it should be extended with an additional cable installed in the cable holder. , so that the bending stress can be reduced to a .

3. The bend radius of the cable should be as large as possible.

3. Servo allowable shaft end load

1. Ensure that the radial and axial loads added to the servo shaft during installation and operation are controlled within the specified values ​​of each type.

2. Be extra careful when installing a rigid coupling, especially as excessive bending loads may cause damage or wear to the shaft end and bearings.

3. Use a flexible coupling to keep the radial load below the allowable value. This coupling is specially designed for servo motors with high mechanical strength.

4. Installation precautions

1. When installing/disassembling the coupling component to the servo shaft end, remember never to hit the shaft end directly with a hammer. Because the hammer directly hits the shaft end, the encoder at the other end of the servo shaft will be damaged.

2. Try your to align the shaft end to the correct condition (if the alignment is not good, it may cause vibration or bearing damage).
