No, the electronics are open on the redundant winding and we have no control over them. The other option being considered is making new stators and adding a third damping coil. This is a painful option as it requires considerable schedule.
The motor is required to operate at its resonance frequency and I am looking to add a thin-walled (0.010") copper tube inside the stator bore to add some damping. The current motor air-gap is 0.015". If I install a copper tube in the stator bore bonded to the stator and leave a 0.005" air-gap...
