The extra HW, all available onchip, would be trivial to add for second motor.
Here is example for one motor, as you can see from right hand window
resources used/left many more available. And this is low end chip, easy to
use the 5LP family for much greater resources. Add a mux to the SAR, and
anolther LUT, Another DAC and Comparator, and misc logic gates, all onchip
for second motor
The board to use is $ 10, or the complete kit (which I don't think you need) -
If you use the basic board you will need the power stage for the motor,
thats not onchip. Those of course these days pretty cheap.
Reference design: supports simple to advanced BLDC motor implementations; including
FOC (Field Oriented Control), sensored and sensorless BLDC motor control implementation
