So I will follow the path to learn more about electric motors.Quote from: fin_rad on February 03, 2021, 08:01:41 PMQuote from: Altema on January 20, 2021, 11:30:39 AM
The Bafang model number is RM G060.750.D 06
Rad controller limits the motor power. The Rad motor internal RPM limiter limits the speed.
Is there any stamps on the motor (inside or outside) where I could identify which model the motor is? Just being curious and interested in learning how the ebike systems work.
The meaning of Bafang model markings:
G060 = casing identification
750 = nominal rating
D = freewheel (DC = freehub)
(6) = winding identification (smaller is faster, no it directly equal to KV)
All Power versions within same casing series are swappable.
Rated model not possible to say what from casing as OEM customers can have custom labeling or motor core can ne swapped.
Rad has done both. In the past casing swap (+sticker) and nowadays custom labeling.
KV can ne identified by no load speed (wheel of the ground full throttle) If you have the throttle.

Quote from: Altema on January 21, 2021, 12:39:30 PMI recall checking the hub motor and controller when it was summer time here and over +20 C degrees - both did not feel even warm after a long trip on PAS level 3-5. More likely the motor is the same than yours and just generates enough heat while riding in winter temperatures that it can melt the snow.Quote from: fin_rad on January 21, 2021, 07:38:29 AMBased on that, it seem to me that the EU motor is different. I have a road near me with a 96 foot elevation gain. I rode my RadMini up it on throttle only, and the motor was barely warm. Same thing after 12 minute rides on mountain bike trails, and I was actually hoping the motor would be able to warm my fingers up, but it wasn't!
Thank you @Altema, that was a clear explanation how these things work.
Not sure if it would be possible that the RPB has used different types of Bafang hub motors under their 750W label? Because the hub motor I got in my RadRhino 750W EU gets so warm on average 350W (PAS 3) and on a 20 km average trip that it can melt snow around it. Until the gears got frozen when melted water turns into ice... So it surely gets warm enough even on some minus degrees (between 0 - -10 C).
