Convert 110v to 240v

Advise sought....

In the early 80's I was able to convert Apple computers (110v US imports) to
run on UK mains by swapping the transformer connections.

Can this procedure be used to convert a 110v cement mixer formerly used on a
building site ? - hence 110v to comply with regulations.

What was the cement mixer? 220v single phase or 208 three phase?
Some 220v motors can be reconfigured for 110v, some cannot. If it's a three
phase, no way. Replace the motor. Unless you want to get into phase
converters and stuff.

I think he wants to run the mixer on 230 VAC instead of 110 VAC. There's
a good chance the motor can be wired either way but you would need to check
it wiring instructions.

How large (HP) is the motor? The only other easy, but heavy, alternative
is a step-down transformer rated to handle the motor load.

Doubtful but possible. Find the electric motor, and look on the nameplate for
a wiring diagram. Some AC motors can be wired for either 120VAC or 240VAC. If
so, you might want to have an electrician take a look at things before you
perform the modification. If there's anything else electrical on the mixer
besides a motor, you should also check to see if that will be OK with the mods,
too.

Good luck

Look at the label for the motor, if it supports 240v you can simply change
the connections to run it off that. If it's 120v only (I would think
unlikely) then you'd have to replace the motor.

Well,

To convert from 110V to 240V get an appropriaty transformer. If you want a
more detailed answer you'll have to provide more info about the mixer.
Another problem you may run into is the 50/60Hz difference. Once more
knowledge of properties or specs of the mixer is necessary.

You more than likely won't be able to do anything about making it run off
230 volts unless you use a transformer. Doesn't matter about the frequency,
it'll just run at a slightly diffeerent speed.
