Need to transform 120v power to 240v

Bad news:

UK has 50 Hz electricity, and appliances are rated for local power..
Any appliance made for US market is rated 60 Hz.
50 Hz and 60 Hz electricity are different.

Look at label on your mixer, and then look at labels on local appliances. You will see 50 cycles or 60 cycles. Rarely appliances are labeled 50-60 cycles.

Hz Hertz or cycles or frequency is number of rotations the electric generator turns per second.

Some appliances are rated 50-60 cycles and will work worldwide.
However most appliances are rated 50 or rated 60 but not both.
60 cycle motor will not perform as expected when connected to 50 cycles. And might overheat.
Generally, most motors can be converted to different voltages by taking motor to motor shop (if you can find one these day)
However electronic controls cannot be converted between 120V and 230V, nor will 50 Hz electronics work with 60 Hz power

Sorry Sue.
Buy another mixer.
Business will benefit from surge of consumer buying.

Why do my clocks run fast when my Briggs & Stratton 15kw generator is running?

Electric clocks use synchronized motors that run on 60 Hz AC. The power company provides AC power with a precisely regulated frequency of 60 Hz. That means that the voltage jumps back and forth (positive to negative) 60 times per second. Your generator would do the same thing if it could run at precisely 3600 rpm (that's rev's per minute) - but it can't, because the engine is not that precisely controlled. In your case it tends to run (on average) a little fast. I hope you found this helpful. By the way, in Europe 50 Hz is the norm. If you run a clock designed for 50 Hz on 60 Hz power, it will run 20% too fast! Al K

We require condenser fan motors for Interclisa Carrier package (rooftop) air conditioner model AAD 250 (1980's model) model. Air conditioner - supply voltage 380 Volts 50 Hz AC. Condenser fan motor voltage...

Hi, this is an odd voltage 380 volts. Is it a 3 phase unit? To get a 220 volt 50hz condenser fan motor, you will have to go through a refrigeration/air conditioning parts house and order this. 60hz you would have no problem finding one in stock. Carrier is a good unit, and have been around for many years. You shouldn't have any problems locating one.
PS You will need to go through a wholesale parts house.

Hi i am washing machine expert. sometimes i thought about to find RPM of any electric motor weather its small or large because its my passion to collect information about my business... so please give me...

i was talk about that... how to check motor RPM? so the solution is....
Calculating Motor Speed:
A squirrel cage induction motor is a constant speed device. It cannot operate for any length of time at speeds below those shown on the nameplate without danger of burning out.
To Calculate the speed of a induction motor, apply this formula:
Srpm = 120 x F

Srpm = synchronous revolutions per minute.
120 = constant
F = supply frequency (in cycles/sec)
P = number of motor winding poles
Example: What is the synchronous of a motor having 4 poles connected to a 60 hz power supply?
Srpm = 120 x F
Srpm = 120 x 60
Srpm = 7200
Srpm = 1800 rpm
