motor 50 or 60 hertz
(OP)
Hello,
I am new to this site and I have a question about a motor being 230 volts 50HZ being sent and used in Hong Kong where there electric is 50HZ and 220 volts. The motor would be purchased from Graingers in the US. I heard that the power overseas has one hot leg and in the US we have two hot legs. So this has led me to some confusion. The power in the US has two 115 legs and they have one 220 leg.

RE: motor 50 or 60 hertz
As long as the ratio volts/frequency is OK, the motor will do its work. So, if you have a 230V/50 Hz motor, the V/Hz is 4.60.
Now, if you connect to 220V/60 Hz motor, the ratio will be 220/60, which is 3.67. That is too much off the ratio the motor was designed for. So it will not work well.
But, if your voltage is 220V/50 Hz, the ratio is 4.40 and that is OK. The motor will work well. The tolerance is usually +/-5 %. So any ratio between 4.37 and 4.83 would be OK.
