Also the driver will have a minimum voltage that will be at lest twice the rated voltage of the motor.
Below this voltage and the driver will not start.

There is absolutely no point in doing "the norm" of using a Voltage several times the rated voltage. Because I'm never going to get to the speed where torque drops inversly with current.
i.e. I should use the rated voltage of my motor.
This sounds too easy (for once)
Comments appreciated.
Thanks

EDIT: Ah but of course at least one quality driver says the Voltage must be at least 4 times the rated Voltage - Other comments still appreciated though. Thanks.
