Smartpie with Kelly KBS48051

[Kris]

I've wired an older style SmartPie (the type without an internal controller) to a Kelly controller with a 58.4v battery. The motor runs OK & responds to the analogue throttle but is very 'growly' compared to the internal controller Smartpies I've setup in the past. Phases are correct (motor runs in the correct direction) & 120 degree hall senders are working (Kelly not flashing any error codes on it's red diagnostic led). Just wondering if I've missed something?

Have tried playing with throttle response timing?

[Kris]

Tried varying that, no difference. Motor draws >20A at full throttle but has no torque. Sometimes won't start without giving it a flick to get it turning.

Disconnected motor from Kelly & wired to smartpie internal controller, works like a dream. Does anybody know if wire colour codes are standardised across the different manufacturers? The smartpie is using blue-green-yellow for the motor phases same as the Kelly so I connected like colours. Hall sensor wise the smartpie uses blue-green-yellow with 5v on red & 0v on black so I wired like colours together & picked up the 5v supply on the appropriate Kelly colours.

Try this:

Kelly controller-------------Motor Phase
A-------------------------------yellow
B-------------------------------blue
C-------------------------------green
Hall Sensors
Hall A-------------------------yellow
Hall B-------------------------blue
Hall C-------------------------green

OK, wiring all sorted. My problem now is the analog regen function. Can't get regen to track brake hall sensor output, seems limited to 20% (the release throttle regen mode limit) or maybe 50% (brake switch only regen limit). What a bugger I only went to all this trouble with an external controller to get analog regen.

[Kris]

Ah ha programming trouble! Analog regen now works nicely. Had to make up a little transistorised brake switch interface because I didn't want to have to press a button as well as wind on the brake & that is working too. Think I'll quit while I'm ahead. Well maybe have a little play now with the 3 running modes, torque, balanced & speed. Happiness is stuff that works.

Yeah I hope those three nodes are working.
When I had Magic Pie 3 only balanced mode was working.

But now I have Crystalyte everything is working fine

[Kris]

Bit too subtle for me, all 3 modes seem pretty much the same.

Looks very clean and fun!
have fun!
