German drill press on US 220v

[Retrosmith]

I've got a Proxxon mini drill from Germany. This one:
http://www.proxxon.com/en/micromot/28124.php

It's got a European plug on it with a ground:

My garage is wired for 220. Can I cut the plug and replace it with a US plug with blue to L1 and brown to L2? Like this:

Or do I need to replace the motor?

The wiring routes through a PCB (rectifier?) and the motor is labeled DC230V.

It doesn't say, but that will be a 50 hz motor, and will probably get hot running on 60 hz US current.

If it's a DC motor running off a bridge rectifier, 50 Hz or 60 won't matter.

50Hz motors run fine on 60Hz, just 20% faster than the data plate says. 50Hz motors are built heavier because lower frequency motors naturally generate more heat.

The reverse is not true. Running a 60Hz motor on 50Hz will likely overheat it.

The website confirms it is a dc motor and it looks to have a full wave rectifier in it - 4 diodes and 2 caps for ripple filtering to get cleaner dc out of it. You should be ok wiring it up to 240vac @ 60hz.

Thanks for the fast responses. I wanted to check before I trashed it. I've got a couple of other tools that I'll double check with Proxxon on.

Yes, and run the yellow, or yellow/green to the ground pin on US plug.

As discussed, since motor is DC, line frequency does not matter.

should be fine , as motor is dc it probably has dc braking for emergency stop

Could you clarify the running hot statement?

 

[big.jim]

dc motor so 50/60 hz makes no difference at all

 

[Alchymist]

Been posted numerous times it's a Dc motor, so line frequency is moot- however, a 50 Hz motor will run on 60 hz, but not the other way round. The lower the frequency the more iron required for the magnetics - one reason aircraft went to 400 Hz - much less iron in the transformers.
