Oisko noin, että 36v moottorin saa pyörimään nopeampaa ilman ohjelmointia, kunhan vaihtaa ohjaimen ja akun 48 volttiseksi?

” I should have been more specific, jumping in here severeal pages later. Earlier in the thread some of us discussed the low maximum cadence allowed with the TSDZ2. Human maximum power need much higher cadences than the motor can handle. In my case, this messed my knees up and also resulted in a broken torque sensor unit (broken axle) because I pushed slow and hard.
As per standard, the TSDZ2 tapers off any assist around 80-90 cadence rpm. AFAIK there is no easy way to simply switch out gearings so I turned to the electronics instead. Buying the new 52V system would, at least theoretically, boost the cadence by (52/48=) 8.3% which isn´t enough if you want to keep an effective cadence around 90. So I stuffed a replacement 36V inside motor in my 48V unit. Alternatively one can switch the controller of a 36V unit: simply install a 48V controller instead of the original 36V controller. The main thing is to pair a 48V battery with a 36V motor. The controller must match the battery but, alas, not the motor! Nota bene: the controllers have a cut-off and won´t start with overvoltage.
My solution won´t increase torque and shouldn´t put any extra load on the infamous blue nylon gear. In fact, unless you increase amps on the VLCD5 torque will drop, since we will only have traded torque for an rpm increase. The 36V motor is wound differently than the 48V, both delivering the same wattage.
I boosted amps from 16 to 20, matching the original torque, while increasing power output the same 25%, hopefully rather safely. I acknowledge temps will rise, but then again, I live in Sweden, so I´ll be mindful of stressing the motor if summer strikes hot, otherwise I can probable ignore the risk of increased wattage resulting in overheating the motor. For me, this has transformed the TSDZ2 from a lazy-ass sunday excursion motor to a real tempo pusher. The higher cadences allows for a sportier ride and more excercise. It will spare your knees and torque sensor unit too.
Hope this makes everything clear.”
