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...

Daihatsu Feroza & 37/47kW Inverter for sale

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.

Brush Timing

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?

AMD is another popular one, what is it? Air Movement Device, a three letter acronym for a 3 letter word.
But seriously, is there some where to set one up if it doesn't already exist? I'm Guessing alphabetically would be the easiest to use.

Clueless take 2

Thanks for all the replies Now if you were using a 3kW industrial motor these are standard at 230V/400V. So using this on a standard 400V controller but with the motor setup in 230V mode means you have picked up a 1.73 gain in nominal power in the motor. So would be 5.2kW nominal and 15-20kW peak d...

Hmmm.... The regenerative braking was one of the major requirements to make the project worth the effort. 20kw may be only 10% of the engines full power but likely more than 30% of it's available power off the mark or when lugging down on a higher gear. 20kw could well be the difference of climbing ...

Thankyou all for your replies. I don't know if it would be practical to power a bus full time via batteries but it's an interesting thought. The major issues are hill starts and hill climbing so the electric assist would only be short term. The ICE can produce around 200kws but that is developed pow...
