Some motors can be connected to a range of different voltages so it is wise to read the rating plate and the motor's Installation Instructions before you try to connect it to any power supply! If a motor was designed and built to run only on 440 Volts it won't run as it was designed to do on a lower voltage of 220 - 240 Volts.
Its spindle might crawl round rather slowly or the motor might just "hum" a bit, but it certainly won't be able to do the job it was designed to do if can only be connected to the higher voltage.
It has to be said that if you needed to ask this question here -- which is a bit like asking "Can a 120 Volt light bulb run on 60 Volts, or 30 Volts, or 12 Volts?" for which the answer is the same: it may glow a bit, or may not glow at all, but it certainly won't light up as much as it was designed to do -- perhaps you should not be considering installing such a motor yourself?
For your own personal safety, if you are not yet qualified to do this kind of job, call a licensed electrician to install the motor for you. He would use the correct type of breakers on the main supply panel, the correct size of wiring for the length of power cable run that is required and the right type of outlet so that the whole setup is done correctly and safely according to your local wiring codes. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS.
If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicator to insure the circuit is, in fact, de-energized.

∙ 11y agoQuoted voltages are always 'nominal' values, and are allowed to vary by a percentage specified by the relevant regulations. 415 V used to be the nominal line voltage for three-phase systems in the UK, and this was allowed to vary by +/-6%; so the machine would have been designed to operate for voltages up to 440 V (or as low as 390 V). The same applies to the 440 V supply to which you are referring; as this is not a standard nominal UK voltage, I have no idea what the allowable variation would be for that voltage but, as it's more typical for actual supply voltages to be below, rather than above, their nominal values, it seems likely that the motor should work fine from a 440-V supply. Besides, all machines will have a factor of safety built into them, which means that they can be subject to higher than specified voltage values for limited periods.

Can a 240 Volts delta motor run on 440 Volts star connection?
If it is a 240 v delta motor it needs a 240 v three-phase supply, which has 139 v between line and neutral, so 440 v would not be acceptable.
Can a 208 415 motor run on 230?
never heard of a 415 motor..
380v motor on 415v?
Answer for European SystemsThe nominal line-to-line voltage used for single-phase supplies in Europe is 400 V. In the UK, this voltage is allowed to vary between -6% and +10%; in other words, it can vary between 376 V and 440 V. So it would be quite acceptable for a 380-V and a 415-V motor to operate on this system.
How do you change a 3 phase 440 volt motor to a 3 phase 220 volt motor?
You can not change it. 440 volt is by design. However you run it with 220 single phase supply, but it would run far lower power.
Will a 500volt 50hz squirrel cage motor run on 380volts 50hz?
No, the voltage of 500 volts is too high to operate a 380 volt motor.
Can a 220 volt motor run on 440 volts?
No it will fry the motor use a voltege reducer

Can a 208 415 motor run on 230?
never heard of a 415 motor..
Will a 370 VAC motor run using a 440 VAC capacitor?
If the motor is rated at 370 v and the supply is 370 v, the capacitor needs to be rated at 370 or more volts, so a 440 v capacitor will be OK.
Can 3 phase 380 volts 50 hz motor run on 440 volts 50 hz supply?
No, the voltage gap between the two voltages is too large.
380v motor on 415v?
Answer for European SystemsThe nominal line-to-line voltage used for single-phase supplies in Europe is 400 V. In the UK, this voltage is allowed to vary between -6% and +10%; in other words, it can vary between 376 V and 440 V. So it would be quite acceptable for a 380-V and a 415-V motor to operate on this system.
Can a 110 volt motor run on 240 volts without damage?
No, unless the motor was wound for dual voltage operation, which it will state on the motor nameplate, a 110 volt motor run on 240 volts will be damaged.
How do you change a 3 phase 440 volt motor to a 3 phase 220 volt motor?
You can not change it. 440 volt is by design. However you run it with 220 single phase supply, but it would run far lower power.
I have a motor that uses 220 volts and 110 volts can it still run if 3 coils are burnt?
i have no idea
Will a 500volt 50hz squirrel cage motor run on 380volts 50hz?
No, the voltage of 500 volts is too high to operate a 380 volt motor.
What is the result of running a 460 volt 3 phase 60hz motor with 415 volts 3 phase 50hz?
It will run hotter. It will run slower, about 83% of nameplate speed. It will draw more than the nameplate current. You will only be able to get about 3/4 of rated horsepower. If the motor is loaded to more than this, it will not live very long.
Will an electric motor rated at twelve volts run faster or slower off of nine volts?
I presume we are talking DC voltages here. The motor will run slower on 9 VDC that on 12 VDC.
