Hi,
For exercise bike, do you know the cheapest way to get it done?
Say a BLDC...and connect pedal shaft to rotor.....then make stator field lead rotor field...ie, make the user pedal the south pole to the south pole, so they feel the repulsion force as they go round....more current...more force (more uphill?)
Or is it cheaper to just pedal into battery (with BLDC in regen) and have inverter from battery regen'ing back into mains. kind of green anergy aswell?
