Clueless take 2

....and the assist between 1,500 and 2,500rpm. OK. You should get plenty of regen pretty much whatever reasonable motor power you end up with - normally it has to be dialed back a bit. The big question now is how much assist power would you like? More importantly, at what motor RPM do you want peak...

Clueless take 2

The motor will effectively coupled to the ICE so operating range will be from 1,000rpm to 4,500rpm. The motor speed will be between 0 rpm and 4,500rpm, most like the regen will be more between 4,500max and 1,500 min and the assist between 1,500 and 2,500rpm. Coupling it direct to the tailshaft could...

In any case it will probably work out cheaper and easier to have a 3-phase motor setup to ~140Vac in delta mode. So it won't really matter which size you pick because it is a custom job any way. I would expect any self respecting rewinder could do this job for you. This sets you pack for around 340...

Combining carbon to create methane makes the hydrogen much easier to store and transport, hydrogen caused serious metal embrittlement and leaks through nearly anything. Is it also very difficult to compress and store as a liquid. The technology for liquefying and transporting LNG is almost old scho...

Thanks Coulomb and acmotor, the compressor in question is for a fridge/freezer, the specs are here , it's a Danfoss DB35 and by the specs the COP improves at lower pumping speeds as does the current draw.

Slow Running a BLDC

This is a general type question. Is there any down sides to running a BLDC at slow speeds? The reason for the question is Danfoss refridgeration compressors use BLDC motors but there COP efficiency can be improved by running them slower than the normal speed they run at using their electronic contro...

The Daihatsu Feroza, you say you've sold the motor and stripped the mechanicals like front diff and gearboxes but do you still have them? An electric 4x4 with an ICE recharge unit till fuel cells becomea reality could be a very interesting project.

If the brush timing was retarded would the motor turn in reverse from stationary or become a generator if it was being driven on over run?

Not meaning to steal your thread here EV Novice but I have a question for the forum. Is it possible to build a DC generator that would also act as a power assist at nom 48vdc so regen would be up around 60vdc?
