Yes, the component can just feed a rotating field to the motor until
index is seen.
This does mean that the machine will move a bit during the motor-homing phase.

I haven't tried that in conjunction with index-based commutation, but
I don't think that they would interfere with each other.
(I think that I would normally choose to home the motor commutation at
machine-on rather than as part of the homing sequence.
