What is the function of electric?
Electrical energy is used throughout the world
to power devices, appliances and methods of transportation utilized in daily life
. To make things operate, electrical energy must be emitted from energy sources such as power plants, to enable an object to consume the power it needs to function.
What is the function of an electromagnetic motor quizlet?
An electric motor is used
to change mechanical energy into electrical energy
. Moving a wire through a magnetic field creates an electrical current in the wire.
What is true about electric motors?
An electric motor is
a device used to convert electricity into mechanical energy
—opposite to an electric generator. They operate using principles of electromagnetism, which shows that a force is applied when an electric current is present in a magnetic field.
What electric motor should I use?
If you want your motor to run continuously and with few gear changes, you should choose an
asynchronous motor
. For dynamic applications, it is essential to have a synchronous motor. Lastly, if you require precise positioning you should choose a stepper motor.
What is motor Basic?
The basic idea of an electric motor is really simple:
you put electricity into it at one end
and an axle (metal rod) rotates at the other end giving you the power to drive a machine of some kind. … When an electric current starts to creep along a wire, it creates a magnetic field all around it.
What is the principle of electric motor Class 10 Brainly?
The principle of the electric motor is based on the fact
that a current carrying conductor produces a magnetic field around it
. A current carrying conductor placed perpendicular to magnetic field experiences a force.
How does a simple electric motor transforms electrical energy into mechanical energy?
Simple electric motors
When an electric current flows through the wire in the electromagnet, a magnetic field is produced in the coil
. Like poles of the magnets repel and unlike poles of the magnets attract. This causes the coil to rotate and thus changes electrical energy to mechanical energy.
What is electric motor Ncert?
Electric motor is
a device that converts electrical energy to mechanical energy
. Parts of a Electric Motor. Insulated Copper wire: A rectangular coil of wire ABCD. Magnet Poles: A magnet as placed above ie North Pole and South Pole.
How does an electric motor transforms electrical energy into mechanical energy?
Electric motors, which convert electrical energy into mechanical energy, are the most common application of
magnetic force on current-carrying wires
. Motors consist of loops of wire in a magnetic field. When current is passed through the loops, the magnetic field exerts a torque on the loops, which rotates a shaft.
What is the process of electromagnetic induction?
Electromagnetic induction is the
process of generating electric current with a magnetic field
. It occurs whenever a magnetic field and an electric conductor, such as a coil of wire, move relative to one another. … A: The coil of wire could be moved back and forth over the magnet.
How do electric motors work physics?
A simple electric motor can be built using
a coil of wire
that is free to rotate between two opposite magnetic poles. When an electric current flows through the coil, the coil experiences a force and moves. … When the electric current changes direction, the same end of the electromagnet becomes its south pole.
What are the three basic parts of an electric motor?
Motor Basics
No matter the type of motor, there are three basic parts:
a stator, a commutator, and a rotor
. Together they use electromagnetism to cause the motor to spin. As long as the motor receives steady current, the motor works.
What factors are needed to consider to ensure that the electric motor will work properly?
- Vehicle characteristics. …
- Driving cycles. …
- Vehicle configuration (electric, hybrid) …
- Maximal speed. …
- Maximal torque. …
- Maximal power. …
- Battery Capacity. …
- Battery Voltage.
Who invented the electric motor?
The first surviving
Faraday
apparatus, dating from 1822, which demonstrates his work in magnetic rotation. Faraday used this mercury bath to transform electrical energy into mechanical energy, creating the first electric motor.
What is the service factor of an electric motor?
Motor service factor (SF) is
the percentage multiplier that a motor can handle for short periods of time when operating within its normal voltage and frequency tolerance
. In other words, it is a fudge factor that give extra horsepower when it's occasionally needed. A SF is an operational margin.
Why are Motors important?
Electric motors are
extremely important
in modern-day life. They are used in vacuum cleaners, dishwashers, computer printers, fax machines, video cassette recorders, machine tools, printing presses, automobiles, subway systems, sewage treatment plants, and water pumping stations, to mention only a few applications.
What does an electric motor consists of?
An electric motor consists of two parts,
the stator and the rotor
. In a motor, the stator is the part that remains motionless and the rotor is the part that moves. The basic principle for all working motors is the magnetic attraction and repulsion.
What is the principle of electric motor by Brainly?
The principle of an electric motor is based on
the magnetic effect of electric current
. A current-carrying loop experiences a force and rotates when placed in a magnetic field. The direction of rotation of the loop is according to the Fleming's left-hand rule.
What is construction of electric motor?
The electric motor construction can be done using the
rotor, bearings, stator, air gap, windings
, commutator, etc. electric-motor-construction. Rotor. The rotor in an electric motor is the moving part, and the main function of this is to rotate the shaft for generating the mechanical power.
What is the principle of an electric motor with the help of Labelled diagram explain it parts?
Ans: An electric motor is a device which converts electrical energy into mechanical energy. The principle behind the electric motor is based on
Fleming's left hand rule
. Working: When a current is allowed to flow through the coil PQRS the coil starts rotating anti-clockwise.
What does an electric motor transfer?
We supply
electrical energy
to an electric motor. An efficient motor transfers most of this energy as kinetic energy (useful work). Only a small fraction is wasted as it heats up the surroundings. … Energy is lost as the electric current flows through the motor's coils.
