Japan 25.2V About 600W Brushless Turbine Fan Superhigh Speed Large Suction Force Brushless Vacuum Motor

Disassembling the Japanese brushless high-power and brushless fan, the loose shell has some scratches and bumps, and the functions have been tested through power on. The fan is well crafted, with a built-in high-power brushless drive. The maximum power measured at 24V voltage is about 25A, and the maximum power is about 600 watts. It is very violent and shocking, with an estimated speed of over 100000 revolutions. The shop owner has seen fans, which are already considered high power.
Note: The shell has some scratches and bumps, and the functions have been tested by power on. mind the appearance, purchase. We do not accept disputes, please understand. Thank you!
This fan requires a 5V start and PWM signal for wiring. This fan requires a 100HZ 5V PWM signal for speed regulation, with a cycle of 5-50%. The speed regulation can only be in four gears, with a minimum of 3A, a middle of 5A, a higher point of 14A, and a high speed of around 25A. The 5V start pin can be directly connected to a 10k resistor in series to the positive pole. The PWM signal pin must be input into PWM to start, otherwise it will not work, so a PWM signal must be used to work. The specific wiring definition is marked in the introduction diagram.
The 25.2V vacuum fan supports 18-30V wide voltage operation, and the motor should operate at constant power. High voltage and current will decrease, while low voltage and current will increase. The minimum limit current can reach 33A under 18V voltage, so the power supply must be greater than the fan power and current.
