Attention: This is a three-phase brushless fan without a drive board, which requires an additional three-phase brushless drive to operate. It does not when directly connected to the power supply, and there is a difference between high-speed and low-speed drives. A new ultra high speed 110000 rpm brushless ducted fan is in stock, with a focus on the low-voltage DC14.4V-16.8V violent three-phase brushless fan, iron high-strength magnetic inner rotor, high- aluminum alloy impeller, high-speed ball bearings, with a power of about 65W. It is not used in the motor of a variable frequency electric blower, but should be used in handheld vacuum cleaners, high-end micro handheld vacuum cleaners with integrated blowing and suction. It has a small volume, weighs only 62 grams but has a power of 65W, mainly due to the strong wind generated by the ultra high speed 110000 rpm, which is beyond the reach of ordinary brushed motors. If the speed exceeds 110000 rpm, a high-speed drive is required. drive the motor normally with the electronic controller of the model airplane, but low-speed drives such as electric vehicles are definitely not suitable for this motor., Weight: 0.13558429113 pounds, Manufacturer: Kueohse
