Brushless Fan Motor DC18V 250W high Power Three-Phase 50mm Super high Speed brushless Motor DIY dust Blower Vacuum Cleaner

MotorsSpecification:Note: This fan motor is out of the box, and some motors have scratches, but it does not affect the use.If you mind, please buy carefully. Thanks.NOTE: Brushless DC motors come with a driver board. It is strictly forbidden to connect the positive and negative poles of the power supply. The red wire is connected to the positive pole, and the black wire is connected to the negative pole. If connected incorrectly, the driver board will burn out.This motor was originally used in high-end rechargeable vacuum cleaners, and the workmanship is very good. The motor is equipped with a built-in brushless driver and a three-phase ultra-high-speed brushless motor. The speed of the motor has reached the level of 100,000 rpm, which is a bit scary. Almost catching up with the aircraft model engine, such a high speed requires extremely high motor balance. All bearings are imported NMB bearings.Note that the driver board equipped with the button board is powered by a 5S , and the working voltage range is about 15-21V. If it is above or below this range, it will not run. This fan needs a signal to run, 5V PWM signal, frequency 50HZ, duty cycle 30%, low gear 3.5A, about 60W, duty cycle 70%, high gear 15A, about 270W. The parameters tested under 18V voltage will be different under different voltages.If the driver board is removed, the brushless model aircraft can work after adjusting the driving voltage to 12V. According to the specific range supported by the regulation voltage, the use of brushless regulation 12V can drive a maximum current of 13A, and the power is about 170W.The weight of the fan is about 180 grams.Motor driver board panel wiring instructions (from left to right):1. Negative pole of the power supply (black wire)2. Positive pole of the power supply (red wire)3. Signal negative pole (black line)4. 5V PWM for 50HZ signal input (red wire)Type B with second speed signal version package
