Frequently Asked Questions
Q1: Are you a professional manufacturer or a trading company?
We are a dedicated manufacturer specialized in HVLS Industrial Ceiling Fans, cooling fans, and exhaust industrial fans, with production capabilities established since 2003.
Q2: What is the primary difference between internal rotor and external rotor PMSM motors?
Internal PMSM: Offers a highly secure structure where NdFeB (neodymium iron boron) magnets are structurally inlaid to prevent detachment, features a high IP64 protection rating, and uses 5 force-bearing points for superior stability.
External PMSM: Features a less secure structure where magnets are fixed with glue, has exposed heat dissipation holes that are vulnerable to dust and water, and centers all force bearings on a single central pole.

1. Equipped with top-tier internal rotor PMSM motors for maximum durability and efficiency.
2. Specialized aerodynamic blades designed in cooperation with top research institutions to mimic comfortable natural wind.
