Update from food processor man
I have a design for a simple limiter circuit that
should be compatible with Dahon + Other models (ie home brew) as an after market fit.
will be deveoping and testing soon....
As previously posted if anyone would like to send me some hardware
I will food process it test it to see if it has a similar limiter to the Pedal Power and return in working condition. I can do this by external meausurment using the processor
I have been told that the PP limiter has less drag than running with the hub switched off. The eWerk appears to be the same.
B+M quote a miniscule figure for the no load drag on the hub when using an e-Werk - far lower than it would be it the hub were simply shorted. Presumably the no load impedance is such that the 50V or whatever that the hub gives only puts a few mA through it.
Counter intuitively shorting the hub reduces the drag
Interesting that we now have reports of Faulty eWerks.....
Colin's PP had a simple assembly fault - the input lead was trapped under a brass pillar and shorting the Hub
