1Pcs Vacuum Cleaner Accessories Micro 55Mm Dc 28.8V 29.6V 350W Ultra-High-Speed High-Power Brushless Motor Built-In Drive

Description 55mm vacuum cleaner violent fan, high-speed brushless worm turbo fan, aluminum alloy impeller, neodymium iron boron high-strength magnetic inner rotor, rated voltage is DC29.6V, It is likely estimated for 7S lithium battery packs. suitable voltage for 350W is DC21V-30V, and the current needs to be at least 15A to drive the suction force. Notes: voltage below 21V, the motor will not start. It supports PWM signal speed regulation and only uses one set of power supply for direct operation, making it very convenient to use. Attention: The brushless DC motor comes with a drive board. It is strictly prohibited to connect the positive and negative poles in reverse. The thick red wire should be connected to the positive pole, and the thick black wire should be connected to the negative pole. Thin red line: PWM (can be connected to the board+5V, maximum speed operation) Thin black wire: LED (indicator light wire) If the positive and negative poles are connected in reverse, it will burn out the drive board. The testing of various voltage and current parameters is as follows: DC21.0V 14.1A (unable to operate below 21 volts) DC21.6V 14.0A DC24.0V 14.0A DC29.6V 12.2A Specifications: Material: Metal Size: As picture Packing: 1pcs Note: 1.
