converting 60hz motor to 50 hz
converting 60hz motor to 50 hz
(OP)
I have a friend visiting from the UK that would like to buy a couple of woodworking tools from the US and use them in England when he returns. The HP on the table saw is 3HP and 2HP on the planer, both are 120/240 V 60Hz single phase. I'm trying to deside which is the best and lease expensive for him. I have thought of buying a new motor for each, rewinding the motors, or a using a transformer. Not being an electric engineer, I would like to get some advice on which is the best solution.
Thanks for your help.

RE: converting 60hz motor to 50 hz
Some single phase motors are rated 120/240 but most are rated 115/230 Volts. The rated voltages at 50 Hz will be 200 Volts and 192 Volts respectively. The horsepowers will be 2.5 Hp. and 1.7 Hp. respectively. It will be difficult to find a transformer of suitable voltage in the US. The transformer voltage will have to be derated. you would need something like 277V/36V. The starting capacitors values may have to be increased, but they are fairly forgiving.
The project is do-able, but the cheapest and easiest is to buy the correct motors in the UK.

First thing I would do is ask the maker of the machine if they can offer a 240v 50hz option direct from the factory and the shipping costs to the UK. They may even have a sales agent here in the UK. I am sorry to appear negative and not be able to offer any realistic suggestions but I cannot see an easy (or cheap) answer to your question.

I agree with waross - buy new motors.

My recommendation; buy those tools in the UK, designed to work at 50HZ, 240 Volts, that is the most economic alternative with proper operational performance.
