    Re: Relocating to US. Can my machine come with me?

    As mentioned in earlier posts, sure, you can run various appliances with motors using step-up/step-down Txformers but this doesnt address the effect caused by a 20% shift in line frequency. It doesnt just cause motors to run at different speeds, it also has a significant impact on the current drawn by the motor windings....

    Going from 50Hz to 60Hz will cause motors to run faster (or anything else that is line frequency dependent, like some clocks) but it will also reduce the maximum output power that a motor can produce and possibly lead to early onset of Rotor Stall.

    Going from 60Hz to 50Hz has the obvious converse effect with respect to speed but it also affects the motor rotor winding current for a given output power. In essence, for the same output power the winding will draw approximately 16% more current which equates to more internal heat being generated. Probably not a big problem with a Super Jolly in a home situation but its longevity in a commercial situation would be significantly shortened. Heat is the enemy of motor insulation....

    As always, matters to do with electricity are rarely straight forward....
