Anyone know what the spacer width is on the drive side?
Those two 10mm spacers you have there in the right blue bowl.
Or, upper left corner on installation hardware picture.

Re: Cyclone 3kW ===> 5kW????

So to visualize it, you remove both halves(gearbox, side cover) of the motor shell and keep only the motor housing metal ring around the stator? Then you put a 80mm pipe through it and bathe it in the potting? Yes but no bathing but pour from top (2 times, 1st only a little), then later when cured,...

Re: Cyclone 3kW ===> 5kW????

Unfortunately no measurements. But similar rides without potting meant motor was too hot to keep hand on it, which is >60C. No such problem after potting, even after a hard ride.
Right now I cant attach thermal image of motor after average commute from work, will do later.

Re: Cyclone 3kW ===> 5kW????

I would suggest potting motor windings with heat conducting polyurethane and buying Nucular 12F controller.
Cyclone 3K @ 60A and 55-60 km/h cont. for 20-25 km in city without motor getting hot. 80A bat / 170A ph when needed.

Re: Bearing upgrades on cyclone 3000? worth it?

Besides bearings, I'd suggest replacing halls and phase wires, install temp sensor and when that all done and double-checked, casting motor windings with thermal polyurethane - to improve thermal path from windings to outer shell.

A big heads up to anyone using BobC's board and following the build instructions, there is a typographical error where it is suggested that the board can be tested by applying battery voltage to the "bat" pin which is pin 14 on the board. If you do that you will fry the DSPIC and depending on the v...

Re: Power PCB for Lebowski Controller to be combined with Bobc's processor board

If I got it right then it's D4 in schematic - BAT54S, a schottky diode, rated for 30V (!).
I was already able to get it locally, but thank you for the offer.

I'd appreciate to hear, what did I do wrong and some advise, how to proceed once I have replaced it.

Re: Power PCB for Lebowski Controller to be combined with Bobc's processor board

So has anyone got their controller running yet?

I wonder what would be best way to power the brain up in order to set initial parameters. ~50V with lab PSU to pin 14 on main connector? 5VDC through halls pin? I would hate to blow something up.

Re: Cyclone 3000w winter project

If you run it at 40A and below then stock mounts are good enough for most cases.
Stock motor chain tensioner needs only one (or two if you're lucky) derailment to render it unusable.
