Under different circumstances of special education environmentMotorEnterprises need a special derivative model, which is actually a social structure derivative model. It is mainly based on the design of the basic economic structure of the motor control series to make some changes, so that the development of the motor has a special protective ability (such as explosion-proof, Chemical anti-corrosion, outdoor and marine use, etc.).Explosion-proof motor is a kind of motor that can be used in flammable and explosive plants and does not generate electric sparks during operation.Explosion-proof motorsMainly used in coal mines, petroleum and natural gas, petrochemical and chemical industries.In addition, it is also widely used in sectors such as textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, and medicine.The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction.Frequency conversion speed motorA general term for motors driven by frequency converters.In fact, the motor designed for the frequency converter is a special frequency conversion motor. The motor can achieve different speeds and torques under the drive of the frequency converter to adapt to the changes in the demand of the load.

These series of structural components and protective measures are part of the basic series of different models of engines, obtained from the environment in which they are used:

Code of special conditions

Hot and humid type, weather protection work occasion TH

Dry heat, weather protection TA

Tropical areas, protected by weather

Hot and humid type, no weather protection occasion THW

Dry heat type, no weather protection work place TAW

Tropical, no weather protection, where TW

Indoor, light anti-corrosion type without code

Indoor, medium anti-corrosion F1

Indoor, strong anti-corrosion type F2

Outdoor, light anti-corrosion type W

Outdoor, medium and anti-corrosion type WF1

Outdoor, strong anti-corrosion type WF2

Plateau weather G

For motors/explosion-proof motors that can be used under special development conditions and different conditions, the special management status code should be added after the motor model when ordering.

Note: 1) Weather protection: Indoors may be well covered (the construction layout can prevent or eliminate the influence of outdoor weather changes, including under the conditions of sheds).

2) Where there is no weather protection: the whole or only simple open-air protection (hardly outside the weather) should be prepared for the impact of changes.
