That is awesome information JuergenH! Thank you so much for sharing that. So here's the specs of the motor I received using the info above to decipher the tag:
AKM 170629 01002 AAD 3620A H
170629 = the date of manufacture (2017-06-29)
01002 = no idea
A = reduction ratio
A = motor inner gear type
D = Stator thickness of the motor
36 = motor voltage
20 = wheel rim (20inch=260)
A = motor type
H = the high torque version (?)
So based on the sticker, not only did I get the wrong motor AAD vs BBD, after
counting the gears, what I actually got was the AAD 3616A when I ordered the BBD 3620A. That's on top of getting a shell with the spoke holes drilled incorrectly and faulty hall sensors.
When I got the replacement shell for the motor The label read:
AKM 171212 200121 BBD 3620A H
171212 = the date of manufacture (2017-12-12)
200121 = no idea
B = reduction ratio
B = motor inner gear type
D = Stator thickness of the motor
36 = motor voltage
20 = wheel rim (20inch=260)
A = motor type
H = the high torque version (?)
Which is correct for what I had ordered.
This just reinforces my earlier belief that I was shipped a lemon and the wrong part lemon to boot. My recommendation for you guys going forward is to get BMSBattery to send you a pic of the motor label before you purchase to confirm that they are sending you the correct motor.
