electricity sine wave

[gdjacobs]

The difference between 2 Sine waves (of the same frequency) that are out of phase is still a sine wave, again of the same frequency, so long as the phase difference remains constant.

Split phases are equal magnitude and 180 degrees out of phase. Each phase is the opposite pole of a transformer and the neutral is a center tap. The biggest potential issue is with earthing.

The frequency change (50->60Hz) shouldn't be a big problem for commutator based motors.

Indeed, universal machines won't have issues but induction motors may.

Hello Jaehoon,

in addition to what Pasi said:
if you still have trouble with the sine test, please tell us what frequency you want to produce, and we will see how to generate the necessary parameters for it.

Kind regards,
