Question on serial numbered Bafang motors?

I ran across this while researching an M600 that I'm tossing around with the idea of buying (yes a CANbus motor). The following is in the dealer manual:

1.3 Product Naming Protocol There is a badge on the housing, showing information as follows:

MM G521. 500 15 033 F5 S329 0001 (sample in manual)
A B C D E F G H
MM G510.1000 12 027 F3 TC1 80122 48V (to keep this as simple as possible, your number from above)

A MM: Mid motor
B G521: Motor model
C 500: Rated motor power
D 15: Number of winding turns
E 033: Connection combination sort
F F5: Measurement and control equipment number
G S329: Date of manufacture, indicating it is manufactured on March 29, 2018
H 0001: Production serial number, ranging from 0000 to 9999; 0001 is the production serial number of the first motor


One point I found interesting is the one regarding the number of turns on the armature. In my experience, the more turns the lower the "design" rpms. So from the "15" in the sample for the M600 motor, we can compare that to the "12" in the number on Don's motor. This info would seem to indicate that the M600 is designed/optimized to run at lower speeds than Don's M620 making it perhaps a better candidate for running the speeds I prefer (10-15mph). Not a huge deal, just interesting. Betting this is one of the reasons the 600 is popular among the off road crowd. -Al

Sorry, the note won't hold the formatting for the A-H spacing when posted. I've broken the numbers up into groups that SHOULD be identified A though H to be referenced below. Might be easier to follow if you open the attached manual. Table is maybe the 3rd page so it's easy to find.... -Al

And absolutely nothing on communication protocol

Thank you
Do you know if this naming protocol is the same for all Bafang motors,
in either Uart or Canbus protocol?
By any chance do you know what the plug type are (male-female coming the motor)?

This is my Canbus motor I have,
MM---G510.----1000.---C12----027---F3--V322---0389 (Motor section, Canbus)
(A).........(B)...............(C)..........(D).........(E).......(F)....(G)............(H)

MM---G510.----1000.----12-----027---F3--TC18---0122 (Motor section, Uart)
(A).........(B)...............(C)..........(D).........(E).......(F)....(G)............(H)

MM---G521.-----500-----15-----033---F5--S329----0001 (sample in manual)
(A).........(B)...............(C)..........(D).........(E).......(F)....(G)............(H)


CR R10M. 1000. FC1.0 A48 YJ V3 053488 (Controller, Canbus motor)

A MM: Mid motor
B G521: Motor model
C 500: Rated motor power
D 15: Number of winding turns
E 033: Connection combination sort
F F5: Measurement and control equipment number
G S329: Date of manufacture, indicating it is manufactured on March 29, 2018
H 0001: Production serial number, ranging from 0000 to 9999; 0001 is the production serial number of the first motor

Tia,

Don, if I run across anything that might help solve your mysteries, I'll be glad to share. Learning as I go as well.....
 
Thanks Al
I have some numbers from a very small sampling of M620 & G510 motors,
I was hoping for about 6-7 of the Canbus same models, 750/1000W
then I can see if the numbering follows thru and make a SWAG etc.

Thanks,
Don

As an update to the above post/info,

Now that I have a small sampling of info on the above,
so far I am 100% correct in that you can ID a Canbus/Uart motors & controllers,
from the info blocks stamped on the bottom of the motors/controllers
and other info about these parts, for the M620/G510 motors.

If you think, I am wrong,
post a clear photo of the spec's block from the bottom of the motor/controller
and I'll tell you what protocol you have for the 750/1000w motors etc.

DO NOT post or tell me what you think it is.............I'll reply with my info,
then you can reply.

Tia,
Don
 
Hey G&T, what the matter, Cat got your tongue?
I have been waiting for a smack down for over a week and no replies? LOL

The G620/M510 motors can be id with the serial numbers on the motor and controller cases and via the connection plug types on the motor,
as supplied via the OEM.
 
On the bottom of the motor where all the info numbers, the UART and CAN are marked in a little code.
