3 phase is not an option for me. The motor controller operates on 220V single phase.
I was able to acquire the motor I wanted, so I will be using the big SRC drive. What I decided to do in this instance is use the exact filters recommended and/or supplied by the manuf of the motor controller.
The in filter is a commercial device and the out filter is supplied by Minarik specifically for their RG series controllers. Together, these filters cost $120, about one third the cost of the controller itself.
The motor is actually a 140V DC servo motor and ultimately I plan to add an encoder and run it as a servo using my Granite Devices VSD drive, powered by a pair of 70V power supplies in series, but for now the SRC will get the job done.
Thanks for your comments.
