[QUOTE="oexing, post: 115884, member: 1493"] Well, for me the case is closed: I am completely satisfied with my test findings, way more power than I ever need. In #93 you find all details about this. I´d recommend the 48 V three phase motor with its 14mm shaft, mid size 300 W or less . The longer types just as good but too much wattage for most but space no problem, same fixing sizes , only longer. This is an idea for those who like to mess around a bit at the lathe, hardware costs below € 100.- including three phase rectifier and 48 to 13.8 V converter, see link for 4 sizes of motors. Total length will be shorter as you don´t need the encoder at the rear end. Alternative is an Alton, provided it is ungeared, otherwise it will wreck its gears due to the non-effective standard ESA. My guess, the Alton should be easier on the Triplex chain as the rotor has lower mass than the one in Miller dynamo, same goes for the 48 V motors, masses shown above in photo comparison. I will need another year or two to finish two B-Rapides for real road tests but am very confident about performances thinking of my tests in my workshop, no air flow, no cooling in half an hour test at 200 W load.

The Series 'A' Rapide was known as the '********' Nightmare?
