Anyone know whether that centrifugal clutch can be replaced by a normal bike clutch, but electromagnetically actuated? If so, how would one do it?

Thanks. I had a look at it. It is bigger in depth and diameter, but is 2Kgs or less, so I will have a look at it and see if it fits my shaft.

I can kill the engine, but, because it is a centri clutch, which engages and disengages only at engine idling speed, and here it is rotating at speed equivalent of 25kmph, it will stay connected. Fuel supply could be disconnected, but you will still be running the engine crankshaft, and hence...

Yes. Exactly. Centri's are designed to only engage and disengage at idling.

It has been remarkably difficult, given that we have no suppliers here, and budget constraints limits us to India, as of now. Common? In terms of car use, maybe. IN terms of 2 wheeler use- none found so far. Proven? Definitely. Inexpensive? Really? Not sure. What would a small one of 12 inch...

Are they? Haven't found any so far. Worth checking. Thanks for the info.

Thanks. One thing to be noted here is that ALL those are machine tool EM clutches. You can make out by the key way in the hole- you don't get such shafts inside a CVT. We did come across that catalog when searching. The fact that it doesn't fit automotive applications is a reason for...

Thats the thing. All the suppliers we know, and the ones in India focus primarily on Machine tool EM clutches, and they don't do single part manufacturing or prototyping. They only undertake bulk orders, for mass production, say. So we would have to design from scratch, and neither do we have...

Well, it is run by a 110cc engine producing 7.88hp and 8Nm torque. DCTs are waaay out of our league. We need a CVT-grade, scooter need EM clutch.

Thanks for replying. 1-4 were not answered satisfactorily. We have been at it for about 2 months, no answer specific, or even close enough to solve our problems. They just confused us further. We know that a direct drive is used in 2 wheelers, but we aren't sure how to make the gear ratios-...

Hello friends, Anyone ever thought of, or tried, or has come across an automobile with an EM clutch, probably electronically controlled? We have a CVT driven 2 wheeler with a centrifugal clutch, but we need to disconnect power at will (electronically), so an EM clutch was suggested. Anyone...

Hello friends, My team is working on a hybrid bolt on setup for a competition. We will be given a 110cc, CVT driven scooter (producing 7.80 bhp @ 7,500 rpm and 8 Nm @ 5,500 rpm). This is the scooter-...

Hey folks, My team currently uses mild steel aisi 1018 for their car chassis. While it is OK, we are looking for lighter alternatives. Problem is that we have to use mild steel ONLY. So I was wondering if any of you could give me a good alternative for 1018 that is lighter, has greater...

@jack action Actually, using turbo compressor as super is the only option for us. You think it will work? Also, assume we get 55 hp, how long do you think the engine will last? Because we use 1 engine for 2 years.

And yes, supercharged or turbo charged air to the engine must be cooled with ambient air only- that's what rules state. EDIT:- @jack action I stay in India. Indian college, so that sponsor is not possible. plus we can build the super from scrap supers and turbos. Possibly taking the compressor...
