Not without adding a phase converter which will cost as much or more than just purchaing a new 1~ motor to use instead. For more information about phase converters if you want to go that route just google the phrase and you will get a lot of hits.

I have a generator designed 440V but the problem is I can use only 220V and the 440V cannot


440 volts is normally 3 phase so unless you have a suitable 3 phase plug it will only be 220 volts
read your user manual carefully

I have Hobart D300 mixer which operates at 220V, 3phase supply and whereas the facility has 208V, single phase supply. Is there any recommended phase converters available for this product. Thanks


Hi Bill
I may be wrong here......
But I've been around Electricity for a long time.
Have Never seen a device that does phase conversion.
A Building site or home will either have Three Phase or Single Phase Power Available
BUT...A portable (Hired) generator could be "three phase" and you could use any one of those phases individually or all three phases.

I have 3 Phase supply to my house!
But I use 230 volt Single Phase for appliances.
My Bore Pump uses a 3 Phase Motor,
(so with a voltmeter it would read about 440 vAC to the pump motor).
Some Further Info:
A GENERATOR is basically a motor used the opposite way. Rotate a motor and it Generates.
The Phases refer to the THREE Windings in the supplying generator in your suburb.
A Large Magnet passes each winding in sequence giving you the three ripples in the supply.
Our houses can choose to have 1 Phase or Three Phases from the street when you set up your electric supply.
So... to confirm, look at the wires on the supply poles to the premises. Usually three in our area (Oz)
Most people are not aware that a car Alternator is actually three phase. The Rotor is the magnet that rotates.
The only difference with an Alternator is that each "Phase" is connected to 2 Diodes (6 total) to convert the three phase to DC to charge the vehicle.
The Regulator controls the voltage to the Rotor, thereby controlling the output.
So.... An Alternator could in theory supply 3 Phase in a mobile generator. Custom Made. Constant speed would determine the frequency of 50Hz or 60Hz.
Not sure what country you are in

Hope this Helps or gives you food for thought!

My 3 phase motor will not start. Just makes a clunk, but wil not rotate. Need help.


Clunk doesn't explain much. Check your voltage in. Unit may have been wired 440 volt and your supply is 220. Make sure you have all three phases coming in.

Motor burned


Single phase 220 volts actually uses two 110 phases to deliver 220 volts. So the failure was caused by something else. The motor winding insulation may have been cracked or previously damaged by high current. The solution is to replace the motor or have it refurbished (not cheap).

Need to know If I can change machine frome 220 3 phase to 480 3 phase Serial # 2664


Hello msc..... A transformer alone can not change single phase to three phase.
You need two things: A phase converter/VFD to convert your 220 single to 220 three phase. Then a step up transformer to boost the voltage from 220 to 440.....

I have a WESTINGHOUSE WELDER type rs 250 that is wired for 440 volt and need to change to 220 volt.


HI:) If that is a 3 phase 440 volt and you want it to use 220 volt 1 Phase you will have to get a phase inverter to change it from a 3 phase to a single phase.

I need a wiring diagram for the Hobart H600 which has a multi tap motor on and i would like to change the voltage on the motor to 200volt single phase 120/208 or even 120208 3phase. The wiring diagram is...


You cannot wire a three phase motor for single phase and you cannot wire a single phase motor for three phase. If you have a three phase dual voltage motor your options are 220 or 440 volts. If you have a single phase dual voltage motor your options are 120 or 240 volts. A 208 volt Hobart motor will only function correctly on 208 volts and is not dual voltage.

Is posible run a single phase electric motor from a source three phase 120/208 wye connection the motor is rated 230 volts AC


It is indeed possible to use ONE Phase to run a motor, You simply use One Phase and Neutral. BUT ONLY if the 3 phase is Double, more or less, the required usage Voltage, EG: 440 3 phase, will be OK, for 220 single phase, . But 220 3 Phase,will not run a 240. single Phase. So in your case is suspect not, it really will do no harm to try though. it just wouldn't work, if not enough "juice", be careful.

I have a 220 440 electric motor on my 4 post 3 ton car lift which ran on 3 phase, how can i run this motor from a single phase supply, regards dave


You need to either change the motor to a single phase or check into a single to three phase converter...I would do which ever is cheaper myself. You could go single phase, but the cost of operation would be higher depending on the duty cycle.
