Stepper Question Unipolar

[xtal]

ASTROSYN Miniangle stepper 23LM-C349-01

1.8 degree 6.8 volt .75 amp Unipolar

the windings measure 9.7-ct-9.7 ohms

1> If I use this in bipolar with 13.6 volt will I get more torque ?????
2> Will I suffer max rpm loss
3> What problems will the inductance change cause
4> ?? will the inductance decrease , I think so but not sure..

When using k179 simple drive,
allegro sla7073mpr[similar to design on Pminmo for sla7062]
and Linistepper.

In unipolar,it appears that 100khz is the max step rate [no load]
before stalling stepper,

3> Does 100khz sound correct ?

1) No. Always run the motor at its rated current hal-winding, 1/2 current full-winding.
2) It will be terrible. 100RPM if you are lucky. The motor needs 140VDC to max it out.
3,4) Full-winding gives 4 times the inductance as half-winding.
3,4) 4-times the inductance = 1/2 the speed. Use half-winding (100RPM).
