Emco pc mill 55 upgrade

[EddyCurrent]

Wish i understood the terminology lol but ill get there, took a pic of motor plate for you if it helps, where about are you located ?

Here's some vfd's as example; https://www.inverterdrive.com/group/...r=Power|0.37kW

The max revs shows 1370 RPM so as not to take it past it's working range that should be about the maximum speed to run it at and that's at 50Hz.
The problem is that reducing the speed will also reduce the power so there's a limit to how slow it will usefully operate at.

The vfd needs to be like this;

Input 230V ac single phase
Output 230V ac 3 phase
Power 0.37 kW (minimum)

where about are you located ?

About 200 miles North of you.
