Hi There,
I have three unipolar 8 wire motors - rated 3V/3A - my question is this.....
Will the following transformer drive three motors - from a discete unipolar drive?
PSU ENC I=220VAC O=5 @ 26A
ENCLOSED SINGLE OUTPUT POWER SUPPLY SUITABLE FOR CRITICAL APPLICATIONS
INPUT: 88-264VAC OUTPUT: 5VDC @ 26A 130W
To my mind the motors should work connected to the PSU and driven by unipolar drives - but I will need 0.66ohm - 6Watt current limiting resistors - in front of each motor.
A friend of mine - that has built a couple of routers - using Gecko Bipolar drives - recogns that the voltage of the transformer is way too low - Could it be because he uses the Gecko's to power the bipolar motors - and that the motors are not connected directly to the PSU - to draw the rated motor voltage and current?
I guess the bottom line is - will the PSU work for my application?
Thanks in Advance for your time in reading this post
Kind Regards.
John.
