What is difference between nominal and terminal voltage?
The rated voltage of a motor listed on the nameplate is called the terminal voltage. This indicates the actual voltage on the motors terminals at which at which the manufacturer designed to operate. Whereas, Nominal voltage is the design or configuration voltage of the electricity distribution system.
How do motors that do NOT use magnets work?
Motors that do not have magnets work exactly the same. The permanent magnet is replaced by a electromagnet, which is a coil of wire with a voltage applied to it. This electromagnet is what produces the magnet field necessary for a motor to operate. It is just easier and lighter to use this style of DC motor in larger applications.
What are the advantages of a silicon-controlled rectifier?
SILICON CONTROLLED RECTIFIER APPLICATIONS i) Speed control for motors ii) Temperature control for electric hot plate iii) Dimmer switch for domestic lighting iv) Dimmer control for stage lighting.
Example of current electricity?
Electric current is that current which generate from electric voltage . it flows on your induction motors also on your computer and your television set's cord and every where which device is operate by electricity. doesn't matter what instrument you are operating. it will flow.
What is LT motor?
LT motors are those motor whose voltage rating is less than 415v.
What is need to operate an electric motor?
Voltage is needed for both AC and DC motors.
What runs on 7 to 10 volts of electricity?
Some small electric motors will operate with an input voltage of 10 volts or less. Some bulbs for vehicles will operate on < 10 volts (but less bright than they would operate at their normal 12 volt input voltage.
What is difference between nominal and terminal voltage?

Whereas, Nominal voltage is the design or configuration voltage of the electricity distribution system.
Will it hurt a 4.8 volt dc electric motor if you put greater then 4.8 volts on it?
Yes. DC motors require the specified supply voltage to operate correctly. Supplying a higher voltage to it will burn up the motor.
Why 440 volt for motor and 220 volt for lighting?
The higher the voltage, the less amperage is required and is easier to supply power to the device. Motors take much more power than lighting, therefore voltages may be higher for easier transmission.
Why doesn't a shunt motor operate on a single phase AC supply?
Shunt motors do operate on single phase AC. There are millions, if not billions of them worldwide running right now.Make certain your voltage supply is correct for your motor. Also, make certain you're providing the proper amperage. Make sure it's not a three phase motor. (three phase motors won't operate on single phase power.) If your supply voltage and amp supply is correct and the motor still doesn't run, you've got a bad motor.
What is high voltage motors and low voltage motors?
None: "high tension" is just another way of saying "high voltage".
What is Low Voltage Motors?
600v or less
How many volts do machines with bigger motors take?
It depends on ampage & voltage of the motors involved.
What will happen when a machine run at low voltage?
The results of operating machinery at a reduced voltage depends on the type of machinery and the power supplies used in the equipment. In many cases, the current drawn will increase to allow a device to operate at a constant power. In others cases such as heating, thermostats will switch on heating elements for longer periods of time to achieve a required temperature. In some simple machines, motors will deliver less power because of the reduced voltage. Although most equipment will operate at lower than rate voltages, there will be a voltage threshold below which it will not operate at all.
Who to increase torque of ac motors?
ac voltage
What is the advantage of using two phase in single phase motor?
Two phase motors are a thing of the past and are not used today if any still exist. Two phase legs are classified as a single phase system. If the question refers to a dual voltage motor then the answer depends upon what supply voltages are available to operate the motor. Operating a motor at the higher of the two voltages means that smaller control equipment and wire feeders can be used to operate the motor. If the nameplate is checked, in the amperage box there will be two current ratings, Amps/Amps. One will be half of the other one. Look at the supply voltage box and you will see the corresponding Voltage/Voltage. The first number in the voltage box corresponds to the first number in the amperage box. The higher the voltage the less line loss will occur over a distance. If possible always try and use the highest voltage to operate motors.
