24 Volt Voltage regulator?

Can anybody point me to a source for a 24 Volt Voltage regulator, or a simple way to build one? I would like to run my 500Watt, 24V cyclone motor off of 36V Bosch battery packs. It needs to handle 40 Amps peak. I'm an electrical engineer by trade, but I've been digital design for the last 10 years, ...

Re: 36 Volts on 500 watt Cyclone kit?

Thanks for the replies everybody. Sounds like it's not a good idea. Maybe I should tear apart some Bosch battery packs and build a 7 or 8 series cell pack instead to keep the voltages in a safer range.

36 Volts on 500 watt Cyclone kit?

Does anybody know if it's OK to run 36 volts on the 500 watt cyclone kit? This is the one where the speed controller is contained in the motor housing. I'm thinking of trying out some of the Bosch power tools 36 volt lith ion batteries on this kit, but it's supposed to only be a 24 Volt kit.

Re: Motobecan 08 Fantom, cyclone 650watts and A123

Looking good. If you need more chain wrap around the motor sprocket, you could move your idler onto the bolt just above the one that you have it on now, assuming the spacing is ok. Then pass the chain over the top of the idler, all the way around and back around the motor sprocket. But you will need...

Re: Motobecan 08 Fantom, cyclone 650watts and A123

Regarding the brakes with the cutoff, the 500 watt kit has these as an option (or maybe it came with the kit, I can't remember). Anyways there were extra ports in the wiring harness so that you could just plug them in. Does the 650 watt kit have any extra ports in the wiring setup? If so, you could ...

Re: Motobecan 08 Fantom, cyclone 650watts and A123

The mount looks nice. One comment I have is since it's only clamped to one bike frame tube, it may rotate around that tube under load or when you hit a hard bump if you are off-road. I would suggest spanning it with a brace across the adjacent tube.

Re: Motobecan 08 Fantom or 09 700DS, cyclone 650watts and A123

No the freewheel on the motor is fine. It is the freewheel on the cranks/chain rings that need to be replaced. If you want to go with something like my setup, you won't use the freewheeling crank and chain ring that comes with the cyclone kit. You would replace that with the IPS system that I mentio...

Re: Motobecan 08 Fantom or 09 700DS, cyclone 650watts and A123

I've used both shimano and dicta freewheels on my front freewheeling chain ring setup, and neither lasted very long. They weren't really meant to be used in this manner with the type of side loads you end up inducing on them. I'm not sure the white industries will be able to handle it either, but fe...

Re: Motobecan 08 Fantom or 09 700DS, cyclone 650watts and A123

The rear suspension won't be an issue if you drive the front chain rings directly like in my setup. If you use the stock setup, then yes, you could have a problem.

Re: Motobecan 08 Fantom or 09 700DS, cyclone 650watts and A123

Hi Kin, The cranks already have a freewheel in them. It's just that the quality of the one that is included in it is not very good. I'm suggesting that you replace the one that is included with the one from white industries. The 18 T stands for 18 teeth. I think only the 16 tooth one will fit, so th...
