A high-power ultra high speed three-phase brushless motor turbine fan with a nominal voltage of 25.2V and a power of 500W. The measured motor speed is estimated to be around 120000 revolutions, and the motor KV value is about 6000. The high-efficiency aluminum alloy turbine blade can be adjusted to a 24V voltage using an aircraft model, and the measured value can reach around 430 . The motor does not come with a brushless drive circuit. Now, only the self equipped aviation model brushless electric regulator can drive it, suitable for the 12-24V voltage range. Under the measured 12V voltage, the current can be adjusted by the aviation model electric regulator to reach around 7.2A, and the 24V voltage can reach 18A, with a maximum of 30V. Originally, it was powered by 7 series of lithium batteries. Pay attention to the rotation direction of the wind blades during operation. If the direction is not correct, the current increase abnormally, and the suction actually decrease. The motor body has a diameter of approximately 56mm and weighs approximately 235 grams.
