Package includes: 1 piece of dc motor
The product will be upgraded constantly, the appearance and color may be changed, please don`t mind. And take a consideration before place the order if you have request for color or appearance.
Brushless motor, built-in drive board, with 100 lines of encoder feedback, equivalent to a miniature servo brushless motor, the model is 24H055M020. it uses imported NSK ball bearings, rare earth in the strong magnetic inner rotor, with pulse frequency speed regulation (1000HZ-26000HZ range effective), can be forward and reverse, with electronic brake, full function, is a high-end precision miniature brushless motor.

This motor comes without a line, we find a ready-made line to match the motor, so the color of the line and the definition of the wrong, so we can only first describe the order of the motor terminals to the motor lead connection, as follows

Now ordered a batch of wire to match this motor, now you can describe the wiring method by the color of the wire, as follows.

According to our current cognitive description as follows
Yellow line: PWM, pulse frequency 16000HZ-26000HZ
Blue line: start/stop, start when connected to the positive pole, stop when disconnected.
White line: electronic brake, release when suspended, brake when connected to GND.
Green wire : direction. Steering CW when overhanging, CCW when connected to positive terminal.
The fifth, sixth, seventh, and eighth pins are the four lines of the feedback signal, we do not understand how to use it for the time being, only know that the purple line (the eighth line) is also GND. the other three lines are just one is +3.7V, two is the signal output it.
Black line: GND
Black line: GND
Red line: +12V (between 10V-13V)
Red wire : +12V (between 10V-13V)
For the correct use of this motor, we do not understand, we connect the motor according to the above wiring method, the motor can operate normally. But as for the feedback signal wiring, we do not know, and our wiring method, there are still some problems, because this motor it is suitable for speed regulation pulse frequency is between 1000HZ-26000HZ, frequency every 1000 HZ, the motor speed will increase 150 revolutions, very accurate, but we test machine found when the frequency is lower than 16000 HZ, according to our However, we found that when the frequency is lower than 16000 HZ, the motor cannot be started according to our wiring method, we use the last conductor of the starter line as the starter method, but it can only be started effectively when the frequency is between 16000HZ-26000HZ. When the start will be able to adjust the frequency between 1000HZ-26000HZ, so that you can adjust the speed of.
This is only a very odd point is that the input pulse 1000HZ it can also start, the input frequency in 16000HZ-26000HZ it can also start normally, is the middle of the pulse frequency (1100-16000HZ) start will jitter, but can not start, as for the technical principles inside, we do not understand.
