I am running three NEMA23 format steppers ( 3A rated ) and a three phase VFD. I will be using shielded cable for the VFD to spindle but wanted to use flat ribbon cable for the motors.
The reason for that is that flat cable from forklift trucks can act as it's own guide, if it has a flat support ( no guide chan etc. ) and has good gauge copper stranded wire.
I have enough conductors to alternate each motor wire with a grounded wire.
max x rate is about 3600 mm/min = 60 mm/sec ; at 80 half steps / mm it will max under 500 pulse / second with harmonics running much higher than 500Hz.
Will that kind of transmission line format be sufficient to control EMI ?
I am currently running a 32V supply to the motor drivers.
Thanks for any advise.
