Can I use the same capacitor of an AC motor rated for 115VAC/60Hz overseas at 120VAC/50Hz?

The same capacitor might be fine at 120VAC/50Hz. But, we can’t give the customer any guarantee, nor is there any UL certification.  If the motor case temperature is less than 90°C after saturation, we can expect the same life time with using at 115VAC/60Hz.

If the temperature is higher than 90°C, we should recommend a different capacitor.  If the customer wants a guarantee to meet certain specifications, we have to evaluate it and then make it as a special product.

Using a three-phase voltage input type eliminates the need for the capacitor and there’s no need to consider the above issue.
