Hi,
I'm still very new to working with BLDC motors, but would like to control a 3 phase, 36V, 5.5A peak current motor directly through an Arduino Uno. I'm thinking of using a DRV3801. My current system uses a separate MCU/driver that I purchased from the motor manufacturer that controls the motor, but this creates lag between the Arduino sending the signal and the motor running. I'd like to reduce communication time this by having the Arduino control the driver directly. Is there a product that I could use for this? I've seen the evaluation boards but do not want to use a second microcontroller again. Would I thus have to create a custom PCB to make use of a driver chip for my application?
Also, are the driver chips inherently able to detect back EMF to sense position and adjust commutation? And would I require additional hardware for the circuit such as h-bridges?
Thanks for bearing with my beginner questions. I appreciate any help.
