Electric Overdrive / Magnetic Gear Motors? / Fixed Gear Drives (Non-Hub Direct Rear Drives) / New Motor Technologies / Custom Belt Drive / Two speed gear boxes for bicycles
This technique is essentially a graphical analysis that gives viable results given the constraint of equal sized wheels and identical motors and controllers:
|for 20 inch wheels|
If you run equal wheels/motors/controllers, you can use simple Infineon trap controllers and will get optimum efficiency under almost all circumstances using a single throttle with no special tuning.
Recommend, would be a CA3 to drive the two controllers to get the throttle ramping, and current throttle for smooth operation + 2WD PAS and/or auto-cruise if you wish... Since the drives are the same, you can use the CA to monitor the temperature of either motor and assume the other motor is about the same temperature. This gets you automatic thermal power rollback to avoid cooking the motors if you try to overtax them.
