Dear experts, Can AC brushless motors (in this case 230V~ 3-phase 3hp motors) that are rated "60HZ" be used in products going to countries that have 50HZ power? I believe the motors will run a little slower which will not affect the function of the product, but is there a safety issue with this? The motors are thermally, overload, and short circuit protected. They are "intermittent use" and not likely to overheat.
As a rule, we only market and sell such products to countries with 60hz power. However, a North America company might purchase one and ship it to one of their international locations with 50hz power without our knowledge. Do we need to be concerned about this? Of course, this fact has our sales force wondering if it is OK to market and sell 60hz motor driven products in countries with 50hz. I really don't know. I cannot see a safety issue but one can say that the motor would be used in a way it is not intended to be used resulting in a higher risk if something did happening. Any opinions on this?
