Protection of servo motor oil and water 　
AServo motors can be used in places that are susceptible to water or oil droplets, but they are not fully waterproof or oil resistant. Therefore, servo motors should not be placed or used in water or oil contaminated environments.
BIf the servo motor is connected to a reduction gear, an oil seal should be added when using the servo motor to prevent oil from the reduction gear from entering the servo motorCDo not immerse the servo motor cable in oil or water.

2、 Servo motor cable → Reduce stress
AEnsure that the cable is not subjected to moments or vertical loads due to external bending forces or its own weight, especially at cable outlets or connections.
BWhen the servo motor is moving, the cable (the one configured with the motor) should be firmly fixed to a stationary part (relative to the motor), and an additional cable installed in the cable support should be used to extend it, so that bending stress can be reduced.
CThe bend radius of the cable should be as large as possible.
3、 Allowable shaft end load of servo motor
AEnsure that the radial and axial loads applied to the servo motor shaft during installation and operation are controlled within the specified values for each model.
BBe extra careful when installing a rigid coupling, especially as excessive bending loads may cause damage or wear to the shaft end and bearings
CUse a flexible coupling to keep the radial load below the allowable value, which is specifically designed for servo motors with high mechanical strength.
DRegarding the allowable axle load, please refer to the "Allowable Axle Load Table" (user manual).
4、 Attention to servo motor installation
A: During installation/When disassembling the coupling components to the servo motor shaft end, do not directly strike the shaft end with a hammer. (If the hammer hits the shaft end directly, the encoder on the other end of the servo motor shaft will be damaged.)
BMake every effort to align the shaft end to the correct state (improper alignment may cause vibration or bearing damage).

When the stator main pole of a two-phase 3.6 ° stepper motor is 4 (which generates unbalanced electromagnetic force between the stator and rotor, so this structure is not encouraged), according to the formula Nr=m (nP ± 1/2), when P=2, m=2, n=6, Nr=25 is obtained. The small picture shows a two-phase, stator with 4 main poles and a 3.6 ° stepper motor structure. Its appearance is a 42mm stepper motor used on a 5-inch 48TPI FDD (floppy disk drive). When it is three-phase, according to the equation Nr=m (nP ± 1/2), m=4，n=4，P=3， Get Nr=50. The number of main poles of the stator is mP=12, and the step angle θ s is 1.2 °.
