Re: noise from CIM motors driven with Victor controllers

The high ripple current caused by the low switching frequency of the Vics will cause more motor heating compared to the higher switching frequency of the Jags, for the same motor torque. Unless you are running the motors for long periods at high torques this shouldn't be a problem; the CIMs are pretty rugged.
