ALCS konvas 15epss stabilized speed controller

[Aapo Lettinen]

I am making a electronically stabilized (not crystal sync but should still be pretty good accuracy) speed controller for 15epss motors.

It is basically a replacement for the original speed control box of these motors as it is getting hard to find the original boxes nowadays. I am making a as-simple-as-possible device with couple of speed presets and which works at 24 volts. No displays or anything fancy. The device is way smaller than the original konvas controller, I am intending using the same casing than my Eclair 16-speed and 12-speed controllers use so very compact.

Price 450usd and should be finished in the next following months.

It is needed to replace the motor connector with new different one and to internally connect the wires inside the motor handle differently so that the motor works at 24 volts instead of original 48 volts. This modification is simple enough to be user made but I can arrange it here too if needed.

Let me know if wanting to order a controller like this. I have possibility to make crystal sync modification for 15epss too but they cost about a grand and most users don't need the features so wanting to see if this simple more affordable device would have use for them 🙂
