    Yep, in short the lower the inductance the lower the voltage you need to achieve a given speed/torque.

    An equivalent circuit for the motor in an ideal inductor and resistor in series. If you increase the voltage the rate of change of current increases, since v(t)=iR+Ldi(t)/dt. This means in a given time the current can reach a higher peak, giving rise to more torque.

    Since the voltage of your driver is limited you need to lower the inductance.

    Talking about inductance i'm thinking:
