1. No protection or specialized protection.


2. Protecting solids larger than 50mm can prevent solid foreign objects with a diameter greater than 50mm from entering the shell. It can prevent a large area of the human body (such as the hand) from accidentally or accidentally touching the charged or moving parts inside the shell, but it cannot prevent conscious access to these parts.


3. Protecting solids larger than 12mm can prevent solid foreign objects with a diameter greater than 12mm from entering the shell. It can prevent fingers from touching live or moving parts inside the shell.


4. Protection against solids larger than 2.5mm can prevent solid foreign objects with a diameter greater than 2.5mm from entering the shell. It can prevent tools, metal wires, etc. with a thickness or diameter greater than 2.5mm from touching the live or moving parts inside the shell.


5. Protecting solids larger than 1mm can prevent solid foreign objects with a diameter greater than 1mm from entering the shell. It can prevent wires or strips with a diameter or thickness greater than 1mm from touching the live or running parts inside the shell.


6. Dust prevention can prevent dust from entering to the extent that it affects the normal operation of the product, completely preventing contact with live or moving parts inside the shell.


7. Dust tightness can completely prevent dust from entering the shell and completely prevent contact with live or moving parts inside the shell.


8. Generator without protection: without specialized protection.


9. Anti dripping: Vertical dripping should not directly enter the interior of the motor.


10. 15 degree angle anti drip: Drips within a 15 degree angle range from the plumb line should not directly enter the interior of the motor.


11. Anti dripping water: Water within a 60 degree angle range from the plumb line should not directly enter the interior of the motor.


12. Splash prevention: Water splashing in any direction should have no harmful effect on the motor.


13. Anti water spraying: Water spraying in any direction should have no harmful effect on the motor, with a standard distance of 1 meter.


14. Anti wave or forced water spraying: Strong waves or water spraying should not have harmful effects on the motor.


15. Immersion: The motor is immersed in water at the specified pressure and time, and its water intake should not have harmful effects.


16. Diving: The motor is immersed in water for a long time under the specified pressure, and its water intake should not have harmful effects. The commonly used protection levels for motors include IP21, IP23, IP44, IP54, IP55, IP56, and IP65.
