45mm Micro Three-phase Brushless DC Motor Fan 100,000 rpm 21.6V 250W Vacuum Cleaner Brushless Motor Turbo Fan DC12V-21V

The dismantling of the ultra-high speed three-phase brushless motor turbine fan has a good appearance, with a full metal shell material, front and rear ball bearings, and a 100000 rpm high-speed brushless motor vacuum fan. The body diameter is only 45mm, making it a very mini fan. The overall quality of this batch of motor dismantling is still good, and it is not ruled out that some impellers may have some dust.

The nominal power of the fan is 21.6V 250W, and the motor does not come with a driving circuit. It can now be driven by a model aircraft brushless electric motor, suitable for the voltage range of DC 12-21V. When measured at 12V, the current can be adjusted by the model aircraft electric motor, and the power can reach around 5.4A. The power is 65W, and when measured at 21V, the power can reach 13A. The power is about 270W, and the effect is quite good. It is important to pay attention to the heat dissipation of the motor. Removing the impeller from the motor shaft is a standard 3mm, and the modification needs to be studied by oneself.

The fan weighs approximately 110 grams.
