I am surprised that they would live with noise generated by the drive system. 

There should be no capacitive coupling between windings and elements. 
Windings are completely enclosed. By using shielded cables the crosstalk 
between the 
cables should be minimized. I have not seen SteppIR antennas, so just 
speculating and surprised that was not eliminated.
