Single phase motor type detection

[Ali-rashid]

We have a single phase motor. we also have a vfd which supports PSC( permanent splitted capacitor) and single phase Shaded pole motors. The pictures of the motor plate and the capacitor on it are attached.
Is this motor categorized in any of the supported types, i.e. PSC or shaded pole? How can I detect single phase motor types?
Thanks in advance

The best way to tell is to open the end bell and see if there is a centrifugal switch. If there is, it's not PSC. If there isn't, it likely is, although it could possibly use an external potential relay.

Use Google to see if you can find the motor specs based on the name plate data?

To ashtree's point:

Yours is the EG71 diagram. Nothing says for sure, but that diagram appears to indicate that it is PSC; no start switch and the cap is in series with one winding.

The relatively small capacitance value and the MKP dielectric type code suggest it's a run capacitor, so another vote for it being a PSC motor.

A more definitive answer - certainly looks like a PSC type.
