Air-gap : the gap between coil and magnet
Axial air-gap :
Direction of air-gap is parallel
to the fan AXIS
Constituents of stator :
PCB, Driver IC
Coreless coil (sans silicon
steels)
Radial air-gap :
Direction of air-gap is
perpendicular to the fan AXIS
Constituents of stator :
PCB, Driver IC, Coil
Silicon steel stack

3-3. Innovations — Comparisons
Traditional fan Risun fan
Radial air-gap with silicon steels
1. Hard to be slim and miniature
2. Hard to be energy-saving due to
the eddy current loss caused by
the silicon steel stack
3. Higher start-up voltage ( >2.5V )
4. Complex process ( 18~25 work
stations in an assembly line )
5. IP ratings : IP55
6. Higher power loss at high temp.
Axial air-gap without iron cores
Patented SMD coil assembly
→ Low profile (4.5mm or less)
→ Low power (saving 20%~40%)
→ Lower start-up voltage (<2.0V)
→ Highly modularized production
(6~7 work stations in an assembly line)
→IP57/58
