New Motor to my ML7

[neer724]

Edit - Please excuse the title - it should have read "New Motor for my ML7" - cant figure out how to update the title?

I have noticed some vibration recently coming from the ML7, so I removed the main drive belt to try and isolate where it is coming from. The motor is starting to make a horrible bearing noise.

It is just a 110v single phase 1725 1/2hp motor on there.

So I thought - what a great opportunity to upgrade to a VFD. I started looking around for a possible VFD solution when I ran across a possible variable speed DC motor solution.

Does anyone have any experience with Leeson Permanent Magnet DC motors? I found is this model:

It comes with a this variable speed controller:

I can get both for 300 brand new.

Any issue with steel swarf and a permanent magnet motor? That was the first thing that came to mind....

Any other motor solutions at a reasonable price?

Thanks,
Steve

Good day. I've never seen a price like that on a DC motor with controller. Sure enough, the ¾ HP, 90 VDC motor and controller are $C728 and $C253 respectively on emotors. I've been looking for a DC motor for my Taig Lathe - I would love to find a deal like that.
Anyway, it's a TEFC - Totally Enclosed, Fan Cooled. You will have no problem with swarf.

I just found this:

It looks doable with promising results....

Both are reputable brands. Lesson has a better warrantee.

I finished installing the Leeson motor today - WOW!!!! What a massive difference. It is pretty much silent now - all you hear are the fenner belts. Love the variable speed....

I found it on Facebook marketplace. Someone bought it to fit it on his meat grinding machine and couldn't get it to fit properly and couldn't return it. I got very lucky finding this....
