I bought a new Enco flavor RF45 clone with a single-phase 1HP motor a little over a year ago. I want to replace the motor with a 3-phase motor and a VFD. Why? Mostly because a nice VFD happened to come my way.

Can anyone help with identifying a physically compatible 3-phase motor in the 1HP-1.5HP range?

I've googled the numbers on the existing motor's nameplate and didn't learn very much about what standard motor frame designation it might be. I emailed Enco support and they didn'nt offer any advice I thought to be useful.

FWIW, the only possibly useful designation on the single-phase motor plate is: YL-90L-4

Thanks!

Check out the attached pdf. These machines use the IEC metric motor dimensions, so the 90L makes sense - and likely the B5 flange option. Double check your motor against these #'s though, as I have a lathe motor with a hybrid mix (larger frame, smaller motor shaft)

Also, I bought my 3 phase 2 hp motor from here https://www.machinetoolswarehouse.co...p-p-16246.html and it was a direct drop in fit - saves a lot of fidling compared to adapting a less expensive NEMA frame motor.
