FIT0441 Brush-less DC Motor Connections?!- DFRobot Forum

2016-12-19 10:59:41 Hi dwwaddell,

Sorry for your inconvenience.
Most of this motor are used in the user's own project, so you need to cut the connector and solder some cables to them. Then connect to the power supply.

Hope this will help you.

What type of connector is this? They certainly can't be connected to an Arduino as they require 12V. dwwaddell

2016-11-21 16:56:33 Hi Mercieca Andrea,

Sorry, we dont sell the motor encoder separately. If its our data error, under the warranty, you are entitled to demand a repalcement. But I have modified the wiki before, did you refer to this wiki to connect?make_clickable_callback(MAGIC_URL_FULL, ' ', 'https://www.dfrobot.com/wiki/index.php/FIT0441_Brushless_DC_Motor_with_Encoder_12V_159RPM', '', ' class="postlink"')

If so, I am afraid that we cant give you a replacement, since probably be caused by your line error, not our product quality issue. If not, more detailed info would help us to know more what happened.

Looking forward to your reply. Wendy.Hu

2016-11-21 03:14:30 Since I practically ran into the same issue and (seem to have) fried the controller, is there a way I can buy the motor w/ encoder but without the gearbox (since it's not broken)? If not, is there a technical term I can use to look up a replacement motor? Mercieca Andrea

2016-09-27 17:06:53 Hi Sir,

Sorry for the inconvenience brought to you and so strange! Could you provide me a picture about your connectors? So I can give a feedback to our team and to update.

The actual connector signals you got is what I said. From the bottom to the top on my picture is white-black-blue-yellow-red(pin1-pin5), the signals are:
Pin 1: PWM
Pin 2: GND
Pin 3: DIR
Pin 4: FG
Pin 5: +12V

the description in the previous attachment same with the signals you got, its just that the colors of your connector is different.

In fact, there are really some problems for the colors of the connectors, its not a good method to connect according to the colors. Wendy.Hu

2016-09-24 06:48:51 Well, I tried it and apparently fried some of controller. At this point the motor is already done in so I opened it and probed the signals.
This is what the actual connector signals are (the motor is oriented as in the picture above):

bottom
Pin 1: PWM
Pin 2: GND
Pin 3: DIR
Pin 4: FG
Pin 5: +12V
top

By the colors of the cable shipped with the motor:
White plug: Blue: PWM, Black: GND, Yellow: DIR, Green: FG, Red: +12V.
Black plug: Yellow: PWM, Blue: GND, Green: DIR, Red: FG, Black: +12V.

I resurrected the motor I tried with signals as above and got motor spinning so my pin maping should be correct.
Unfortunately it appears that it spins at constant speed regardless of the applied duty cycle of PWM.
This is quite understandable since in the previous attempt 12V would be connected to GND while 0V would be connected to PWM, while the VCC and GND would go to the control signals of the Arduino.
So the Arduino control signals were hard trying to power the motor!
Arduino seems mostly fine (tested with scope/signal generator), but the USB hub gave up and died, probably saving Arduino.

I seriously suggest to get away from colors. Just describe the pinout of the connector!
Specially if the motor has a connector, not a bunch of cables coming out.

I fact none of the motors we ordered had the colors of the wires following the documentation! But in the case of other motors the connectors were described or in the cae of steppers the coils can be easily found. Bogdan.Baudis

2016-09-24 01:04:03 HI Wendy, so juts to be sure: from the bottom to the top on your picture the signals are: GND, +12V, FG, PWM and Direction? GND at the bottom and Direction on top? Bogdan.Baudis

2016-09-23 22:05:23 Hi Wendy, Thank you for the prompt answer! I suggest you stop bothering with colors, the cable I got with the shipment has yet another arrangements of colors than the one in Wiki, or the description of the connector in your reply or the one in the picture. Once I know which pin is 1 and what are the pin functions I can progress.
I will assume the pins are starting from the bottom as on your picture: GND, +12V, FG, PWM, Direction. I will try that and let you if I get motion (or smoke ...).
If you are curious my cable has one connector white and the other black; the white connector has a sequence (starting from Pin 1): blue, black, yellow, green, red; the black connector: black, red, green, blue, yellow :-)

The cable still useful, I can use the connectors and I need to cut wires anyway.
Cheers, Bogdan. Bogdan.Baudis

2016-09-23 11:40:09 Hi Sir,

Sorry, I checked the order of the cable and found that the picture in our wiki is wrong, I will modify the wiki later. You can refer to the following picture, pin1 is the white, pin5 is the red, and the description is right(dont look at the label):
('0', 'L_`{LO33{Z0H}_6)U02(TKY.png')
('1', 'U}8MQ1KBPZ[A78Z87(ZN`6X.png') Wendy.Hu

2016-09-23 05:54:15 FIT0441 Brush-less DC Motor wiki shows an example of use make_clickable_callback(MAGIC_URL_FULL, '(', 'https://www.dfrobot.com/wiki/index.php?title=FIT0441_Brushless_DC_Motor_with_Encoder_12V_159RPM', '', ' class="postlink"')).
However the order of colors on either connector of the cable supplied with the motor assembly do NOT agree with the picture!
Should I believe the colors on the cable (which end?) or the picture and description of the connector?
I assume Pin 1 on the connector is on the left when looking at the face of the motor with the connector with the connector pointing down. Bogdan.Baudis
