Product description
Tips: If you need large quantity, we can provide wholesales for you. Thanks Tips: The product may be updated constantly, the color and appearance may be changed, please don't mind. And take a consideration before place the order if you have request for color or appearance.
Specification:
The DuPont wire we are sending now has no locking points on its plug. It can be equipped with motor sockets on both sides, so it cannot be defined by the color of the wire.
The terminal can only be defined by the motor socket.
The positive and negative poles of the brushless motor drive board are strictly prohibited from being reversed. Please carefully check the wire connection before powering on and testing the machine.
Pin 1: FG (suspended without wiring)
Pin 2: PWM signal, connected to the positive pole through a series of 10K resistors, with the fan running at the highest speed.
Pin 3: GND (common negative electrode of power supply and PWM signal)
Pin 4: Positive pole of power supply One thing to pay attention to when using this brushless motor is that the positive and negative poles of the power supply should conduct the slowest, which means that the PWM line should be connected first and then the power supply should be connected.
The motor can start normally. If the pilot is connected to the power supply and then the PWM signal is connected, the motor cannot start. This is the design of the driving board, and it is not because the driving board is damaged.
Motor weight: 32 grams
Power: 20W
Steering: CCW
Voltage: DC12V
No load current: 0.65 A
No load speed: 25800 RPM
Voltage: DC15V
No load current: 0.72 A
No load speed: 31500 RPM
If a PWM signal is input on the second pin, the duty cycle can be used for speed regulation, and the negative pole of the PWM signal should also be connected to the third pin in parallel.
The following measured input pulse signal of 10000HZ, voltage DC12V, measured current and speed under different duty ratios: (Please note that if the frequency of the pulse is different or the voltage changes, the speed and current of the motor will also change.
We test the motor with a signal of DC12V and a pulse of 10000 Hz.) 10% 3409RPM 68 MA 20% 8822RPM 165 MA 30% 13000RPM 264 MA 40% 16200RPM 345 MA 50% 18600RPM 405 MA 60% 20500RPM 450 MA 70% 21900RPM 480 MA 80% 22900RPM 500 MA 90% 23900RPM 520 MA 99% 25800RPM 580 MA
