I own the CV1800 with the Leeson single phase motor. I am planning to purchase the Baldor 3 ph motor Clearvue sells unless I find something else with the same specs but in 3 phase.
I have a very knowledgeable person on the Hobby Machinist forum I am a member of that found a 5hp output variable frequency drive I am planning to run the motor on as I do not have 3 phase. My plan to deal with the noise is swap the motor and run the machine with the vfd and use a speed potentiometer to allow for variable speed. That should be a good start to dealing with the noise.
I contacted Clearvue about this and they said absolutely I can do it with no harm to the motor. Apparently Australia and countries that use 50hz have been doing this for years. Wish I had known about this when I purchased it in 2019.
Clearvue also told me they are currently working on a silencer and are claiming around a 10db drop. If that’s true I’d be interested. That and variable speed would be good for me.
I designed a noise closet but it’s going to take up to much space and have decided against it.
My questions for any owners are.
1. What model number is on the data tag of the 3ph motor? Baldor or Leeson. I can’t make it out on their site.
2. For those using variable speed how much of a reduction in noise is there. Quite a bit I would imagine.
3. Which vfd are you running?
4. Which brand and model are you using? I’m not tied to Leeson or Baldor just what Clearvue sells and so far there Baldor 3ph is the cheapest I have found it online. $950
