Help wiring EC12 for Europe's 230-240volt power source.

by Philip

I moved to Europe from USA.

I want to wire my EC12 air compressor for use on Europe's 230-240volt power source. What must I do to make this happen?

My EC12 air compressor is:

Currently wired for 115volt (USA).
Single Phase.
FACON 40uf 450Vac 50 Hz Two Prong Capacitors (2each).
Two Pole MDR21-EA-11 Pressure Control Switch / 240Vac / 50-60 Hz.

There are three wires running from the plug, to the pressure control switch, through to the motor - Hot, Neutral, and Ground.

From the motor, to each capacitor, there are two wires each (a hot and neutral wire), and from the motor there is one ground wire which is attached to external housing of the motor.

This is good news, in that the motor was relatively inexpensive.

Thanks for the update, and solution.

Mission Accomplished !!!

What it came down to is a simple 'swap' from the U.S. 115volt (center casing, rotor and stator) to the European 230volt (center casing, rotor and stator). The center casings were the same dimensions, so the swap was simple. It only took 30 minutes to swap. The original U.S. motor required two start capacitors, whereas the Euro motor only required one capacitor, so I have a spare capacitor now. I paid only $48 U.S. dollars for the part plus labor. I'm very pleased I didn't have to purchase a new Euro compatible air compressor.

Before getting this work done, I had come to believe that simply rewiring the motor from series to parallel (or vise versa) would solve the 115v to 230v supply issue, but this was not the case. In the end, the rotor and the stator is different (more or less wire windings, etc).

Okay. Will update post soon as I get info.

I will post update soon I get info from Hitachi.

That is an induction motor, so that may not be possible.

I'd contact Hitachi and see if there is a replacement rotor and/or stator for it to run at 230. You may need both, which amounts to a new motor.

Let us know what you find out please.

Good luck.
