Disassembled ultra-high-speed three-phase brushless motor turbo fan, good appearance, all-metal shell material, front and rear ball bearings, 100,000-rpm high-speed brushless motor vacuum fan, the body diameter is only 45mm, a very mini fan, this The overall condition of the batch motor disassembly is still good, and it is not ruled out that individual impellers will be a little dusty.
The fan is nominally 21.6V150W, and the motor does not have a drive circuit. Now it can be driven by a model aircraft brushless ESC. It is suitable for the voltage range of 12-21V. The measured current of the model aircraft ESC can run to 3.8A under 12V voltage. The power is about 45W, 21V Under the voltage, it can run to 9A multi-power 190W, the effect is not bad, the motor must pay attention to the heat dissipation of the motor, the motor shaft is a standard 3mm without the impeller, and the modification needs to be researched by yourself.
The fan weighs about 102 grams.
