Please tell me, what is a dust-proof motor?
Thread Content
Two days ago, I was talking about dust-proof motors with a friend. I have never heard of this before. It seems that there is no special name for it, because the protection level of the motor, IPXX, already includes the definition of dust-proof. The first digit indicates: Prevent the human body from touching or approaching the live parts and rotating parts in the shell, and prevent solid foreign objects from entering the motor. The second digit represents: Prevent harmful effects caused by water entering the motor. The meanings of the first and second digits are shown in the table below. ； The meaning of the first digit: 0 Unprotected motor 1 Prevent > φ 50mm solids from entering the housing 2 Prevent > φ 12mm solids from entering the housing 3 Prevent > φ 2.5mm solids from entering the housing 4 Prevent > φ 1mm solids from entering the housing 5 The second digit of the dust-proof motor: Prevent harmful effects caused by water entering the motor. See the table below for meanings ； The second digit represents the meaning of the number : 0 Unprotected motor 1 Vertical dripping of water has no harmful effects 2 The motor is tilted 15 degrees from all directions, vertical dripping of water has no harmful effects 3 Water splashing within a 60-degree angle to the vertical line should have no harmful effects 4 There should be no harmful effects to withstand splashing water from any direction 5 Withstand any direction * * There should be no harmful effects. My friend said that their motors are used in crushing situations, and there is a lot of dust, so they require dust-proof motors. So I would like to ask you about the knowledge about dust-proof motors, whether the protection level is higher, and how it is different from ordinary motors! Thanks in advance!
This is a new type of vertical waterproof and dustproof motor, including the motor body, flange front cover and shaft head. Its characteristic is that a waterproof round boss is provided on the flange front cover with the shaft hole as the center. The cavity at the bottom of the shaft head is sleeved on the motor shaft and matched with the waterproof round boss on the flange front cover. When the motor is installed and used on a gemstone grinding machine, it can effectively prevent the coolant when processing gemstones and the dust mixture remaining during grinding from entering the motor and damaging the motor, thereby extending the service life of the motor. * * Improved performance, fewer failures and high work efficiency. It is especially suitable for installation and use on gemstone grinding machines and in working environments that require waterproofing and dustproofing.

I seem to understand a little bit. Can the friend upstairs send some structural drawings or appearance drawings? It would be much better!
How much can a waterproof and dustproof motor with high power do? How is heat dissipation achieved (not used in water, but it must be waterproof and dustproof)?
Regarding the knowledge about dust-proof motors, the protection level and ordinary motors follow the same standards, and there is no big difference from ordinary motors. Such environments include grain, food, and feed processing. Taking into account dust explosion hazardous locations, explosion-proof motors must be selected.
