I am starting to work on undergraduate project to build electric skateboard. Main thing I will foucus on, will be ESC (electric speed controler) made for a motor 190KV (motor spec.). I got micro-controller STM32F401 Nucleo and expansion board Nucleo low-voltage 3-phase motor driver STSPIN230. But here I got questions. This expansion board got low voltage range between 1.8 to 10v, but BLDC motor will be powered by 24 voltage battery supply. My main idea is to program a low-voltage 3-phase driver and at the outputs(U,V,W) design a circuit which can boost power to my motor.
1.)Is this possible to build a circuit with 6 MOS-FETs at the end of low-volage Nucleo drive to boost output power and current for BLDC motor?
2.)Can this board make a output torque for low speeds?
3.) How hard is to design a smooth operation ESC that will speed smoothly and not have jerky brakes?
My main consern will be at the end, this ESC will power motor which will push heavy load (human 80 kg) down the road. I am trying to come close to a VESC product speciffically made for electric boards. A size of my ESC is not limited.
