BLDC55 55mm DC 28.8V 29.6V 350W High Power Speed Brushless Motor Fan Handheld Vacuum Cleaner Fan Motor Pwm Built-in Driver

Motors55mm vacuum cleaner violent fan, high-speed brushless worm 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. Moreover, it is produced by a professional of brushless fans, with stable and reliable quality.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.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:DC21.6V 14.0ADC24.0V 14.0ADC29.6V 12.2AThe lead wires of this batch of brushless fans are two thick wires and two thin wires.The thick red line is connected to the positive pole,the thick black line is connected to the negative pole,and the definitions of the two thin lines are as follows:Thin red line: PWM, connect the +5V on board, it run highest speed.Or conect 50K resistor to the power+, it run highest speed.Thin black line: LED==========Hign-concerned Chemical : NoneColor : blackModel Number : 29.6V 350W Brushless Motor FanContinuous Current(A) : 12AConstruction : Permanent MagnetProtect Feature : Explosion-proofType : Micro MotorCommutation : BrushlessEfficiency : IE 1Origin : Mainland Certification :
