Thread: Selecting the right driver

Hi,
What I would like to know is, when selecting a driver unit for use with stepper motors, should we be matching the driver amp rating to the same amp rating of the motor or do we really only need to select a driver that is half the amps of the motor ?
So if I had a motor that was rated at 4a, would that be 4a total regardless of the number of phase’s or divided by the number of phase’s?
So in this case it is a two phase motor rated at 4a, two phase’s at 4a = 8a so I would need an 8a driver or am I right in thinking only half of the motor (one phase) is in use at any one time?
What happen's when the current is moving from one phase to the next are they both in use at the cross over stage?
Thanks,
