三、One-page Guide to Model Selection by Industry
What device do you have?
Belt conveyor / Crusher / Mill / Bucket elevator → Frequent stalling?
WF-SN Stall Protection Type (Preferred!)
Fans / Water Pumps → Less stalling & energy efficiency pursuit?
WF-CV Energy-saving Type (Adjustable Air Gap)
Oil pumping units / Non-concentric shaft equipment → Shaft misalignment?
WF-CP Integrated Type
Nuclear power / National defense / Energy storage → Zero leakage & ultra-high reliability?
LG Synchronous Type (Bearingless)
Chemical sealed equipment → Toxic and hazardous media?
LG/LS Synchronous Type (Physical Isolation)
