My thoughts exactly, maybe its a single phase 240V sander? If it is 3 phase I would go for a boost transformer, or new motor.


Sorry guys, it is actually a 220V motor 3 phase. It is on a belt sander. I built a new starter for it as it was not CSA approved. It is European. I was getting nuisance tripping on start up so I just increased the value a bit. Seems to work great now.


220V 3-phase would be pretty unusual in Europe.

Normally you would only find equipment designed to operate at either:

230V 50Hz Single Phase
or
400V 50Hz Three Phase

or, in the UK and Ireland for construction site equipment :
110V 50Hz delivered as split-phase i.e. 55V on each leg, this is designed to prevent dangerous electric shock in the event of cable damage, even without relying on GFCIs/RCDs. Such equipment is supplied via a local step-down transformer.

Previously these were :

220 V and 380V in Continental Europe and Ireland
and
240V and 415V in the UK

EU/CENELEC Harmonisation moved Europe to 230V/400V
