Micro Cooling Fan to launch Voltage

Understanding "Micro Cooling Fan" to launch Voltage: What are the factors that influence the engine fan voltage means a minimum wage job voltage operation voltage, is a fan of good and bad characteristics comparable low friction coefficient generally net fan, and a bathroom with a lower? operating voltage of the Hall IC to enable fans to lower electric start.
 Influence "Micro Cooling Fan" launch factor voltage
 1. Winding depict whether appropriate.
 2. The size of silicon hysteresis loss.
 3. The minimum operating voltage of the Hall lC.
 4. transistor expand multiple irregularities.
 5. magnetization intensity rubber magnet.
 6. component blades "Micro Cooling Fan".
 7. bearing friction coefficient of irregularities.
 8. transistor full voltage irregularities.
 9. whether there is a reverse diode maintenance.
