How do you change an electric motor to run on 120V instead of 240V?

Many motors have the ability to run on 240 or 120 volts. There is typically a diagram on the rating plate on the motor that shows you how to wire for either voltage. Sometimes you need to install or remove jumpers. If your motor is not dual rated you can't easily convert because if you just connect 120 volts to where 240 volts were connected you will draw twice the current which isn't good for a lot of reasons.

What is cheaper to operate 120v motor or 220v same horsepower?
220 volt will use less energy.
What are the fireplaces that are electric called?
They are called Electric Fireplaces. They come in many styles, colors and designs. They can be either plugged into a standard 120v outlet or hardwired to the home at 270v.
Can a motor work as a generator?
Turn the shaft ;)A brushed-commutator dc motor can be turned into a generator by connecting its shaft to another source of power to make it turn at the correct speed.A diesel or gas engine - or another type of electric motor, such one that runs on 120V or 240V single phase ac - could be suitable.
Which cost less to operate 120 v appliance or 220 v appliance?
For the most part, they cost about the same. For instance, if you look up a 120V, 2hp electric motor in a catalog, you will find it draws about 18A. 120V * 18A = 2160 watts. If you look up a 240V, 2hp motor, it will draw about 9A. 240V * 9A = 2160 watts. Watts are watts. Watts are what you pay for. It takes a certain amount of power to perform a particular task, irregardless of the voltage supply. You typically see larger loads, such as a dryer, range or AC unit fed from 240V. This is because the lower current draw permits you to run smaller wire, which is less expensive to install.
Are 120V and 208V the same?
no 208v is bigger
Can you change electricity from 120V to 240V in your kitchen so that you could use a new electric oven instead of an old gas oven?
No The wiring isn't big enough to carry the load of an electric range Christmas is no time for a fire! Call an electrician!
Example of electric potential?
120v
What is the wattage of 3A 120v Electric Fan?
360 watts
What will happen when the shunt motor is connected across the supply line directly?
If the motor is designed for 120V or 220V whatever the case, it will function properly.If it is a 12V motor and you supply 120V it will make a mess and you will probably get hurt from flying debris!
You are building a new house and trying to decide between 120v and 240v which is better More practical?
In the US, both 120v and 240v will be needed for your home, as different appliances need different voltages. Your TV needs 120V, while your electric dryer and stove will need a 120V/240V supply. If you have an electric water heater, or central AC unit, they will need a 240V supply.
Where can you find a 120V electric power cable?
One can find a 120V electric power cable in stores such as Lowe's or Home Depot. It can also be purchased online through the store websites or through sites like rakuten for a cheaper price.
What are the power requirements, and how do they rank with other similar electric drills?
Electric drills typically require 60-120V DC grounded power cables.
How do you turn on an electric fireplace?
Electric Fireplaces are simple to start. Plug them into a standard 120v household outlet and press the power button on the unit; or on the remote control.
What is cheaper to operate 120v motor or 220v same horsepower?
220 volt will use less energy.
What makes a 480 motor with up down and stop 120v switch work?
I think I understand what you are asking. 3-phase motors usually are equipped with a starter or contactor, since all 3 hot wires need to be switched. The control voltage that runs the starters is 120V, because it's safer and also 120V switches and relays are cheaper. You would have a 480-120V transformer (called a control transformer) in the starter box to provide the 120V "control voltage". So the arrangement you describe would have two contactors, with two phases reversed between them. Energize one, and the motor runs forward. Energize the other, and it runs reverse. The switch sends 120V to each of the contactors, which are equipped with 120V coils.
An electric iron uses 8.3a of current at 120v calculate?
8.3 A. times 120 V = 996 watts
In a home has 120v service there is an electric appliance that a risistance of 12 how much power will this appliance consume?
1440 Watts
