Chriull Posted June 20, 2017 Share Posted June 20, 2017 Has anyone an idea how high the resistance of the phases (coils) of the EUC is? Taken some measurements or estimated the used wire length? i'd like to have an idea in which magnitude it could be. From pictures like posted here http://forum.electricunicycle.org/topic/6742-gotway-acm-1600-autopsy-and-mods/?do=findComment&comment=84088 there seem to be about 55 magnets, so also ~55 coils. Every coils could have about 10-15 windings in ?5-10? layers (not really to be seen). Would result in 50-150 windings (*) with ?4? cm each -> 200 to 600 cm per coil -> with 55 coils in total something between 11 to 33 meters. (imho with this accuracy all the wiring around the coils can be neglected ) Somewhere was written that AWG 16 wires are used? They have 13,6 Ohm/km so the resulting resistance for all three phases could be in the range of 0,15 to 0,45 Ohm. Normally 2 phases are always commuted together in serie, so the range for the "effective" ohmic internal resistance could be somewhere between 0,1 and 0,3 Ohm? Taking in regard (*) 0,1 could be a realistic value for further estimations? (*) Just discovered that the linked picture are 7 pictures - it's hard to tell from them but imho 50-150 windings is too much, could be even less than 50 windings per coil?
