I have 3 SLO-SYN stepper motors
TYPE: M113-FJ40
OZ.IN:1100
STEPS:200
VOLTS:1.3
AMPS:20
HZ:DC
Iam looking @ gecko drives to power them. I know that the gecko is 7 amps max output ,does any body know if these stepper motors will kneed 20 amps to operate or is the 20 amp figure the max the steppr can take. If this is the max the stepper can take then the gecko, providing there is not to much resistance in my slides should work fine up to 7 amps with heat sinks?????

Torque is proportional to current, so if you run them with 7 amps, you will get 7/20 of the static torque.
