I have an application coming up where we will be driving a brushless DC 3 phase motor from battery packs. The motor does not have hall effect sensors.
Each pack will have its own motor for that voltage of 36v, 56v or 72v. We are looking to make1 board to handle all 3 voltages (Ranges from 28v to 83v lowest battery to highest battery voltage)
The nominal power output for each voltage would 1300 watts with peak power output around 2000 watts. The peak is still under discussion.
I would be looking for a smart controller that we could feed a PWM or analog signal input and let the chip take care of all of the phase switching and current limiting.
I am looking at the TI DRV835x family of parts. It looks to be an all-in-one system, simple drive interface with current feedback. It can handle a motor without internal sensors.
Is this where I should be or do you have another recommendation?
Thank you
Ben
