A brushless servo motor will usually have 3 motor leads (and who knows
how many sensor/encoder leads). So, right off the bat, you have to
figure out how to connect a 3 wire motor to a driver with only 2 terminals
for the motor.

A brushless fan motor or similar unidirectional motor will only have 2
leads,
but it will also only run one way. Most have protection diodes, so it
will turn one direction, and act as if it was not connected when the drive
tries
to turn it the other direction.

If you were to hook 2 of the 3 wires of a brushless servo motor to a Gecko
brush motor drive, it would jerk one way or the other, but not continue
rotating. The Gecko would probably get a very quick overcurrent fault
after that.
