1. The flameproof grade of the explosion-proof motor can meet the requirements of the flammable and explosive environment. Do not choose the high grade.

2, according to the actual use of explosion-proof motor technical indicators, technical indicators η, cos φ the higher the better, save energy, the rest of the explosion-proof motor indicators are not necessarily. For example, when driving the motor of axial flow pump and fan, the Tst can be in the range of 0.6~0.8, and the Tm need not be high, and about 1.6 can meet the use requirements. If the buyer loosens up a bit on these two indexes, the designer can supplement the surplus function from this to the Ist, that is, to reduce the Ist. This is of practical significance for the use of explosion-proof motors with small network capacity. The load of the motor is mostly fans and pumps, high Tst is not necessary. If the manufacturer pursues this target too much, the cast aluminum rotor groove shape of the upper half of the design is very narrow, to increase the unnecessary difficulty of manufacturing; There are many faults caused by broken strips and thin strips in use.

3, explosion-proof motor protection level to choose moderate. The difference between IP54 and IP44 is mainly in the dustproof function. In order to save money, some buyers choose IP44 explosion-proof motor in the place where IP54 is used, so that the explosion-proof motor bearing is damaged prematurely. On the contrary, if IP44 meets the requirements, you do not need to select P54. The latter should be equipped with rubber sealing ring, maintenance is not as good as the former.
