U.S. machine to Czech
(OP)
We are looking at sending a paint shaker to the Czech. It has a controller on it that runs a DC motor. The shaker runs off of 120v 60hz. I can use a transformer for the voltage but what about the DC on 50hz? Is this going to be a problem? From what I know DC does not change direction so it probably wont be affected because of the bridge rectifier and capacitor. Am I way off base?

That should tell you if it can deal with other powerline frequencies.

We had another poster here a few months ago that was bringing equipment in for a trade show. In his case he could simply rent the power converter (if he chose to do so).
I presume a paint shaker has a moderately-sized AC motor. That motor probably won't be happy running on 50 Hz if it was designed for 60 Hz. But one could probably purchase an equivalent 50 Hz motor that would bolt on. Doing these kind of modifications requires appropriate knowledge and skills (if not qualifications). There's also the issue of import rules (e.g. "CE" mark).

Ayup. The Czech Republic is a member of the EEA. If your product is not tested/certified to CE requirements, you won't get it through their customs...if the inspectors are doing their job.

Note on AC motors on 50 Hz
Most AC induction motors run about 5/6 speed when switched from 60 Hz to 50 Hz. There are also voltage issues. (Volts per Hertz)
I believe that there is a FAQ on 55/60 Hz conversions.
