The motor has the ability to operate on two different voltages and still maintain the motor characteristics of the nameplate specifications. As the voltage goes down the amperage will go up in value but the HP and RPM will remain the same.
You can't. You must supply the motor with it's required voltage. If it's a dual voltage motor, follow the wiring schematic on the motor nameplate to switch from low to high voltage.
If you make the connection, the breaker on the generator will trip. The motor will not get up to running RPM. Check and see if the motor is dual voltage. If it is, run it on the higher voltage. This will reduce your run current to about half of what it is on the lower voltage.
On some motor nameplates you may see 120/208-240. These are not true tri-voltage motors. They are dual voltage motors with a leniency on the 240 volt range to be derated to run on 208 volts. At this voltage the current drops and you don't get the full horse power rating of the motor. To answer your question I have never seen one that would do true three voltages like 120/240/480.
It depends on the device, if for instances the machine is a pc, laptop mobile phone charger or anything that has a modern switch mode power supply built into it then you can use it on anything between 110 and 240, it will auto select, i don't recommend attaching a machine that is rated at 240v to a 460v supply, you will need to contact the manufacture to determine operating parameter's.
How do you calculate voltage drop for starting motor current
Need to know what the dual voltages of the motor are.
You can't. You must supply the motor with it's required voltage. If it's a dual voltage motor, follow the wiring schematic on the motor nameplate to switch from low to high voltage.
The wiring instructions for wiring a dual voltage motor are on the underside of the lid of the motors junction box. If it is not there look on the Internet for winding dual voltage motor connections.
Short answer: No. (unless you like ruining motors) Longer answer: Not really, but there are some motors that can be re-wired so that instead of 440v they will run on 220v. However, this is not that common. Conclusion: Check the motor to see if it is dual-voltage on it's nameplate. If it is, you can re-connect it to work on 220v. If it is NOT a dual-voltage motor, you will absolutely ruin it if you connect it to 220v.
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.
The wiring diagram is on the tag on the new motor. The two additional wires are either for rotation reversal or it`s a dual voltage motor. If dual voltage you must determine what voltage you are using and follow the diagram to match the motor to it. If there are any unused motor leads they must be capped individually.
If you make the connection, the breaker on the generator will trip. The motor will not get up to running RPM. Check and see if the motor is dual voltage. If it is, run it on the higher voltage. This will reduce your run current to about half of what it is on the lower voltage.
As we know that P=VI, and P is a constant value for any particular motor, so if the voltages will drop current will increase so that the product of V and I be the that particular constant value for any particular motor
These types of motors are classified as dual voltage motors. The highest motor voltage rating is always double the lowest voltage rating. Dual voltage motors are more versatile in matching the system voltage supply that they are connected to. When the motor uses the highest voltage rating the coil legs are in series, dropping the high voltage across two coils. When the motor is connected to the low voltage rating the coils are connected in parallel dropping the low voltage rating across the two coils in parallel. As you can see no matter which configuration that you use the individual coils can never get a voltage across them greater than the lowest of the two voltages available. The connection diagram is usually on the underside of the motor's junction box lid.
If you mean a dual voltage motor 120/240 then yes these will operate on a 240 volt home distribution system.
Yes, the device is compatible with 100-240v dual voltage.
A dual voltage processor is the type that can use two different voltages. This feature allows a processor to be compatible with more motherboards.
