My controller, after 10-15mins or so of riding (the longest I've done so far), is getting rather hot. I can't hold my hand/finger on it for any longer than 1-2 seconds. It still works, but I'm concerned something is going to go up in smoke soon.
My system is as follows:
- 36V 15Ahr Ping battery, which seems fine and doesn't heat up at all
- 36V 350W Keywin/ecrazyman controller (as advertised - doesn't have a sticker on it to confirm this), with regen.
- Yucheng geared (no freewheel) motor. Was advertised as 36V, 250W, but bought used and I'm unsure as to whether seller really knew details. Hub gets warm.
Unfortunately I don't have the means to measure current at the moment. Top speed is around 26-27km/hr (16-17mph), which seems a little low for 36V, but perhaps the geared motor is wound for slower speed.
I haven't finalised the controllers position yet. So far it has just been sitting on top of the battery. Not great airflow, but not enclosed either. Whilst it isn't positioned ideally (and I will fix this up), I don't think position of the controller is the primary cause.
The 3 phase wires on the motor are rather small. A lot smaller than the controllers, which are a lot smaller than the batteries! About 2mm (0.075") overall diameter including insulation!
Any comments on what could be causing the controller to overheat?
Thanks.
