Magic pie regen
« on: January 21, 2010, 04:32:41 PM »
Is it correct that with the Magic Pie motor, the battery needs to be in place and turned on.  I think I understand that the controller would be burned up when the brakes are applied and the motor regenerates.  If this is the case, you couldn't use the bike just for excersice with the battery removed to cut weight.

Hi andto the forum.

I think this is the information you are looking for:

Quote from: Yao Yuan (GM Representative)
We have recently enhanced the cruise controller to detect if the battery pack is in place. If the battery is switched off, or is not connected at all, the controller will check the back EMF voltage, if it exceeds the preset limit, the controller will disable the regenerative braking to protect controller from being damaged.

As of today, 22/7/2009, the day of the eclipse, all GoldenMotor controllers have a new function to deal with the issue of regen braking burning out the controller while battery is off.

It should be fine to use the bike just for excercise with the battery removed, but if you leave it attached you'll get even more exercise.
With the battery fitted, you would have the option to turn it on when you were completely worn out!
