What happens to a 240v electric motor if you hook up the same phase 110v to each of the 2 lines

If you are using a 220V-240V appliance at 110V, you will need a transformer. If you are using a 110V appliance at 220V-240V, you can also use a transformer but may be able to get away with a (cheaper) converter though not with all appliances.

didnt specify to much --generic answer -- sounds like hooking up a heating or cooling unit black and white should be your line voltage use a meter to test your black and white line for 110v if motor is 110v the low voltage lines are control or switch lines that dont go to motor they usually go to a thermostat or transformer

the voltage required is stamped on the plate on the electric motors
it will read
voltage
phase
current( watts)
duty cycle that plate tells you what the motor needs to run

Hi,
Here's what I think but you will have to check it out...
The fan motor in the 39 heater is a 120V fan there fore it cannot be hooked to the 240 which potentially could have the high (wild) leg as one of the fan legs...
The 240V 36 unit probably has a 240v fan motor....
Now if you were to make sure that the leg that fed the motor was a 120V to ground leg then you will be okay...
Hope you understand where I was going with this...

Its not really clear to me where your measuring once you plug in the dryer, but all phases are measuring the correct voltage before, it appears you have an open circuit once you plug the dryer in. Now a dryer is 2 phase, so I would check all of your wiring connections, I would also check your circuit breaker and try swapping it out with a new one(as a last resort). Do some experimenting. In a dryer the heating elements are the only thing that runs on the 240V power. I would swap the hot leads in the dryer and see if any of the electrical components come on. Also try testing the continuity on your dryer plug wires to make sure there isn't a break in them (which can be proven by swapping the leads because now the same lead will read 0V on the other terminal).

110V is our common household current and 220v is used where heavier voltage is needed, like ovens, stoves, clothes dryers, air conditioners, electric water heaters, arch welders, etc.

For to use it with a 220/ 240vac system,you will need to convert 110vac 60hz/to240vac 50 hertz single phase therfore your transformer should have this rating,also it has to be able to handle up to 3kw or 3000watts in power, maybe just as cheap buying a new drier....

Your dryer is electric. This means it needs 2 electrical phases (hot wires) and one neutral to wor. If you measure 110v across 2 phases - one of them is out.
Unplug the dryer. Find the double breaker for your dryer on the breaker panel.
Pull breaker to the off position hard (do not overdo it,as you can pull the breaker out), and then back to on position.
Check voltage between the two phases, it should read 220-240v. Check the voltage between each phase and the neutral (middle prong), should read 110-120v. If you don't get these readings - call electrician.
If you get the proper voltage, plug the dryer back in. If it does not work - Dryer needs repair. Likely a thermal fuse is blown or problem with power wiring inside.

Does your generator is single phase generator set or three phase four wire generator? Why your generator set is 110V at full load, it should be 220V or 240V to generator electricity. If it is used for industrial equipment, it should be 380V, 400V, 440V, etc.

There are two systems in use in the states
110v dryers are available that fit a standard 11v 15a socket
110/220v fit the oversize 'dryer' sockets, and they are two 110v phases 90 degreees apart
the motor runs of a single phase 110v.
there is 220v between the 'outside', the active lines of the two phases, at any time, but it is not useable to provide mechanical power as a single service, due to the complicated shape of the wave form when you add out of phase voltages together, but is ok to drive the heaters, they have no mechanical efficiency requirement
A 2 phase 110v heater it means 3kw can be supplied without a 30 amp circuit
but it becomes difficult to use a single phase 220-240v transformer to provide 2x110v 90degree 2 phase current unless you specially buy one in. .
High power applications in 220-240v are generally supplied by 415v 3 phase 60deg supplies,

Any transformer would be onsellable at the end of your posting, to your replacement, who would doubtless be in the same boat as you, with a heap of 'stuff' that needs to run.

UK Aus NZ may be sources of transformers, or dryers to suit.
check with Australian UK NZ suppliers as well as local Indian ones, as those countries are also nominal 240v single phase home suplies and they may have (1) the dryer, or (2)the transformer to suit the 110 2 phase dryer
