Re: Stepper Motor Shielding

Hi,

What I recommend is you use a 5-wire shielded cable. Here's how it
works. 4 wires go to the motor windings of course. The 5th wire is
connected to the motor case. Connect the other end to your power
supply ground, near the drive if possible. Connect the shield braid
to ground at the same location where you ground the 5th wire. DO NOT
connect the motor end of the shield anywhere. Leave it floating. This
will keep the motor wires from interfering electrically (noise) with
anything else.
