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. 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. 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: Ehwisbe
