Can you convert motor winding 50 hz to 60 hz?

Answer 1

60Hz frequency on 50 Hz motor will create more resistance in its coils. Will cause electromagnetic force trying to increase the speed of the rotor by about 20 %. Less current will flow but the torque will be less, because of the increased resistance of the coils. Usually if the motor is not loaded much it will work fine on 60 Hz. One solution if there is problem running the motor is to remove part of the all coils equally from all of the bobbins by 10-20% .

Comment

The resistance of the coils will remain unchanged, however, their inductive reactance will increase -thus reducing the current.

Answer 2

Many will run on 60 hz but do so at your risk. They may overheat the motor. Voltage must be right. e.g. a 250v 50 hz fan motor from Britain cannot be used on 110v ac 60hz. But may work ok on 220v 60hz.

I agree with the above.

Generally, 50 Hz gear will work on 60 Hz, as the equipment has enough iron in it to present enough reactance so's it doesn't draw excess current and overheat. What it may not do is to deliver as much power as it would have on 60 Hz.

The big problem is with 60 Hz gear operating on 50 Hz. If it's near its maximum power rating, the lower amount of iron (by 50 Hz standards) can allow excess current and overheating. I saw this is in the 1960s when folks brought 60 Hz U.S.-made TVs back to our 50 Hz systems. Even though the voltage rating was OK, they tended to overheat due to the lower frequency.

Answer 3

You would need to change the gear ratio inside, as the rotor is synchronous, and the 50 Hz clock motor would be 20% fast on 60 Hz.

Answer 4

You need a frequency convertor if you want a HZ motor to run at Hz with the same speed and power.
