Fiber band is wrapped up entirely, and two ends end hoop is fixed, and enhances the intensity of end；End hoop material is terylene sheath glass-silk rope, with general
Logical steel end hoop is compared, and has processing simple, easy for installation, good insulation preformance, good economy performance；Stator lead-out wire is that copper cash is straight
Connecing extraction, save cable soft wire, decrease a welding node, this not only saves material cost, decreases the event at node
Barrier hidden danger, also simplify processing technique, has saved production hour cost, and copper cash directly leads out and draws heat radiation than cable soft wire simultaneously
Effect is more preferable；Stator lead-out wire colligation, on fixation hook, alleviates the weight of stator leading-out terminal end, and improves dissipating of end
Thermal effect, improves the reliability of motor；3, the air intake protective cover of band sand proof net can effectively stop the tiny grains of sand to enter electricity
Inside machine, the structure that sand proof net clamped by this two-layer protective cover enhances the stability of sand proof net, and rubber filler rod can increase protection
The sealing of cover, also can reduce the vibrations of protective cover；4, removable U-shaped dehumidification heater, convenient installation and replacing, strengthen
The moisture-proof function of motor and maintainability；5, from wire box cabling on cable rack, making motor volume little, compact conformation, copper bar makes 90
Degree bending facilitates terminal block.
