The code and meaning of the motor operating environment

Under special circumstances, the motor needs a special derived model, which is actually a structural derived model, mainly based on the basic series of structural design of the motor, so that the motor has a special protection capability (such as explosion-proof, chemical anti-corrosion, outdoor and marine, etc.).

Some structural components and protective measures of these series are different from the basic series, and the derived models of the motor use environment are:

special circumstances code

Damp-heat type, weather protected location TH

Dry heat, weather protected TA

Tropical, weather protected occasions T

Damp heat, no weather protection THW

Dry heat, non-weather protected location TAW

Tropical version, no weather protection TW

Indoor, light anti-corrosion type No code

Indoor, moderate corrosion protection F1

Indoor, strong anti-corrosion type F2

Outdoor, light corrosion-resistant W

Outdoor, medium corrosion protection WF1

Outdoor, strong anti-corrosion type WF2

plateau weather G

For motors/explosion-proof motors used under special conditions, the special condition code should be added after the motor model when ordering.

Note: 1) Places with weather protection: indoors or places with good shelter (its architectural structure can prevent or reduce the impact of outdoor weather changes, including the conditions under the shed).

2)No weather protection places: all open air or only simple protection (almost impossible to prevent the influence of outdoor weather changes).
