In the last couple of months I have somehow blown 2 cyclone controllers which i am pretty annoyed about. They were both from cyclone and are 40A rated (100A burst) controllers one rated to 60v other was up to 72v.
Both had the same symptom - randomly stopping entirely, and there is a small click from the controller when I turn the throttle now. Also they had worked much harder previously than at the moment they failed (first failure I was just slowly cruising along on flat)
I am a little confused about current limiting in e bike controllers. I admit I did push the motor really hard up hills and accelerating, because I thought that if it was going over the rated current it would reduce the output to save the FETs. I was under the impression that normally you cannot destroy a controller by demanding too much from your motor? unlike RC ESCs of course. Is that wrong?
I am very reluctant to buy another cyclone controller and am probably either going to get a Lyen 12FET 72v or this infineon 12FET which seems similar http://em3ev.com/store/index.php?route=product/product&product_id=82
But with either of those controllers will I still have the possibility of breaking them or do I in fact have to be careful with controllers?
I ideally want something which won't fail randomly and can be pushed hard without worry, will the infineon be able to do that?
If that might fail randomly I might as well get another cheaper 40A cyclone.
I'd really appreciate some controller knowledge.
Thanks
