Does anyone have experience how to rewrite Magic Pie 2 motor?
what all the options and opportunities I have?
I want to ba a higher final speed!!!
Whether to try with higher voltage and how to protect the controller?
Can i put the stronger elements in the controller?
Does anyone have experience with improvements to this electric motor?
What can I expect with any corrections?
I have a four pack of batteries 48v-10ah lifepo4.
Is there any chance that this motor runs on 72v or 96V!?
Whether to try other mosfets and what?!
The internal controller will work to 60 volts max, so your 48 volt might charge to 52 volts, so that's about the maximum you should use with the internal controller.
You need an external controller for higher speed and voltage, the pie is a slow wind high torque motor and will do 35 mph max on 60 volts with a controller such as the Infineon with 120 % speed setting in the controller.
All this means you have to open the motor and extend the 5 sensor wires and 3 phase wires. Or sell the pie and buy an 8T mac kit for cell-man. It will do 31 mph max on 48 volts.
Going for faster speeds means higher voltage
Look around the forum there is loads of information on the pie.
Back to pedal only power.
