I have a prototype of a small BLDC motor, and I'm looking for a driver evaluation kit to get it up and running. The current will be less than 3A, the torque very low, probably less than 0.1 N m. I'm not yet concerned too much about speed but ideally at first would like variable between 60 rpm to 600 rpm. I'd like to explore sensorless operation and operation with Hall sensors.
Is there one driver that can accommodate both either separately or at the same time? Or do all sensored drivers also use current sensing at the same time?
I have DRV10983 evaluation board, and it does spin the motor at low speed, but any change in the parameters causes a stall ... but I'll address that in a separate post. I also have a C2000 Launchpad Development Kit and a BOOSTXL-DRV8301-CB board, but haven't tried it yet. Neither of these accommodates Hall sensors.
What would be a good choice for a driver for sensor and/or sensorless operation?
I've found the DRV8308EVM, which seems to be a potential choice, but if there are other options, I don't want to overlook them.
While I'm at it, for ease of use in just getting the motor spinning and controlling it, which choice is better: the DRV10985 kit or the DRV8301 board?
