Hi All
I am making the upgrade to vfd and 3ph need to know which motor frame I need.
You help I'd need an appreciated, thank in advance.

I have helped a few people with 932/940 VFD conversions in the past. The stock motor is a metric D flange mount direct drive 90S (a 90L also has the same flange dimensions), but I recommend you pull it out and measure it up to compare to online motor specs. If I recall the standard available motor replacements the shaft dimension was larger (24mm) then the PM 932 motor shaft (stock 932 shaft was something like 19 or 20 mm). If you are looking for a drop in 3 phase replacement I believe you will need to get a 3 phase replacement motor from Quality Machine Tools. I cannot find the previous post on the 932 VFD conversion.

Well I put the caps in the PM932m today and it didn’t fix the problem. So I guess it is something in the motor.
