Hi,
after my first experience with DIY EV bike (https://endless-sphere.com/forums/viewtopic.php?f=28&t=73027&hilit=cyclone+1680+overheating), I moved on with a new project, an electric trial motorbike.
I choose Revolt 120 pro with 30 Kv managed by a Kelly controller KLS7230S for my new project.
I just finish to assembly all components obtaining what you see in following pictures.

If someone is interested, I will post the full building log as soon I fix my actual overheating problem.
Here are some specs:
Engine: revolt 120 pro 30kv directly connected to the wheel (datasheet says 6kw - 15kw peak)
Controller: kelly Controller KLS7230S 72volt 300A max
Battery: 2x Hobbiking 16S3p 60v 15ah
After I completed all settings required on the Controller and double checked the wirings, I did my first ride test today.
The result: after 30 seconds of ride the controller stopped working
The problem: engine overheating! more than 170°C
After the walk of shame, I checked the temperature on the controller, it was still too high, maybe too much considering a flat riding of less than a minute with 10°C degree.
The following checks has been already done
- checked the wiring to avoid wrong readings that come from engine termistor
- reset controller and made a new Identification Angle procedure (to identify the right hall sensor phase)
- checked all the parameter using Kelly manual http://kellycontroller.com/mot/downloads/KellyKLS-SUserManualV1.10.pdf
- reduced the max controller output to 50% (less than the engine rated power)
- the engine spinned smoothly, also the torque was awsome. Should I assume that the controller settings were correct?
- the engine was really overheated, I checked it out touching it
Here are my configurations
Am I missing something to check? what are the possible reasons of this kind of overheating?
Any suggestion is appreciated!
Thanks!
Stefano
