electrical supply conversion

06/30/2008 2:01 AM

I wanted to know if there is a cost effective way to convert 50hz 220v supply to 60hz 110v. I am buying a used machine with a load of around 10KW its 60hz 110volts but in my country we have 220 volts 50 hz.

Hello combined

Your Question is confusing to any reader.

First you say: I need to convert 50hz 220v supply to 60hz 110v.

Then you say: I am buying a used machine with load of 10kW it is 60Hz 110 Volts.

Then you say: in my country we have 220 Volts 50Hz.

So, as you may see, there is information which conflicts with other information.

Note that "Used machine" as below, means the one you are buying.

So: Could you reply please with the following (use the number system):

  1. Your Country (You can place that in your Profile if you wish, then it will show always, so useful for others)
  2. Your Country's Voltage (We can find that out, if you don't know, once we know your Location)
  3. Is your used machine you are buying, a Diesel powered Alternator = "A Genset"?
  4. Is your used machine you are buying, an Alternator, to be powered by a stream, turbine, windmill, or other - please advise
  5. The Voltage of your used machine you are buying per Alternator nameplate
  6. The Frequency of your used machine you are buying
  7. Number of phases of your used machine (The one you are buying)
  8. The used machine you are buying size in kW
  9. The load you intend connecting, to your used machine you are buying, in kW
  10. The Voltage of your load you intend connecting, to your used machine you are buying, in Volts
  11. The Frequency of your load- (If heaters and incandescent lights only, the frequency should not matter)
  12. The number of phases required, for your intended load
  13. Any other useful information.

Reply here please, with

That way, the problem is clear to CR4 Members, who may then be able to give you a proper answer.

Kind Regards....

I will make the question simple:

I get 220volt 50hz power supply from the power distribution company I want to convert it ti 220volts 60 hz is there a cost effective way of doing this.

<...220volt 50hz power supply from the power distribution company...220volts 60 hz...cost effective way of doing this...>

In the original post it was 110V 60Hz. No wonder there was confusion!

Inverters can be found that will change incoming 50Hz into outgoing 60Hz quite economically.

Another cheap option would be to change any motor for replacements suitable for the supply in the new country of operation.

Combined; I wouldn't worry about it, the motors will run faster,(1750 vs 1550 rpm, or 3570 vs 2950 rpm, ) perry

The point about the motors is fine but what about other electrical equipment like temperature controllers and infra-red heaters?

hi my self is divyesh

it is easy to get desired voltage of any level with the help of transformer but the desired frequency can not be achieved by transformer for that u have to go for drive

variable frequency only.

normally drives gives variable frequency variable voltage.

Unless your equipment is frequency sensitive I would not concern yourself about it. motors and heaters can usually handle a 10 Hz difference and switch mode power supply's are not sensitive to frequency variations within reason.
