Sealing between lid and rotating shaft, improves degree of protection, in addition the length length of fin, and area of dissipation is big, and fin one
The cover that end part extends into wind scooper is intraoral, and the wind for avoiding fan blade from blowing out extends out, and guiding wind is blown between fins, thermal diffusivity
It is good, this threephase asynchronous machine energy long-time normal work used for air compressor.
In above-mentioned threephase asynchronous machine used for air compressor, terminal box is fixed with the top of described casing, described connects
Line box is fixed with lid.It is so rational in infrastructure, reduce volume, and be easy to wiring.
In above-mentioned threephase asynchronous machine used for air compressor, a side wall of described terminal box offers two wiring holes,
Plastics waterproofing cable connector is fixed with each wiring hole.Such easy-to-connect, plastics waterproofing cable connector ensure that wiring
Sealing water proofing property at hole.
In above-mentioned threephase asynchronous machine used for air compressor, the nylon of frame-shaped is provided between described terminal box and lid
Pad.This ensure that the sealing water proofing property between terminal box and lid.
In above-mentioned threephase asynchronous machine used for air compressor, the screw top of described casing is connected with suspension ring.So just
In carrying.
Compared with prior art, this threephase asynchronous machine used for air compressor is compact-sized, is totally-enclosed, fans cold type mouse cage certainly
Type threephase asynchronous machine, degree of protection is high, reaches IP55, and the class of insulation is high, reaches F levels, and thermal diffusivity is good, can for a long time just
Often work, operating efficiency are high.
