  • 50HZ to 60HZ Chassis Conversion

    I converted a 50 Hz Chassis to 60 hz by replacing the T1, T2 and Sweep and table contactors. Everything seems to be working okay. Did I miss anything?

    if you are changing voltage 230 to 115 you will need to change thyristors, also what Hz are the motors. wrong hz runs hot.

      Honestly, with the chassis, IMHO nothing really needs to be changed. We have 16 110V-50Hz chassis on our machines that have been running as-is w/ no mods (minus the 5-boards... we have MK70/MK70EX boards) for well over 10 years now. No real problems so far... they run as well as the 60Hz ones. We run a lot of 50Hz motors, too. You can run 50Hz stuff on 60 w/ no real problems (they just run a little faster)... but like it was stated...60Hz equipment on 50Hz is a no-no (they overheat and blow up).

        I believe the contactors on a 60hz chassis are wired in parallel compared with a 50Hz where they are wired in series. Yes / No?
        Also spot / respot solonoids to be changed.

          Transformers should be OK on either frequency. Most 50Hz chassis were wired for 220V operation, though.
