What is a motor generator physics?
What is a motor generator physics?
A motor and generator perform opposite functions, but their fundamental structure is the same. Their structure is a coil mounted on an axel within a magnetic field. The coil then creates a magnetic field that interacts with the already existing magnetic field. This interaction forces the coil to rotate.
How do motors and generators work?
A generator converts mechanical energy into electrical energy, while a motor does the opposite – it converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field.
How does a generator work physics?
Electric generators work on the principle of electromagnetic induction. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. The magnetic field will interfere with the electrons in the conductor to induce a flow of electric current inside it.
What is the difference between the physics of motor and generator?
The main difference between the two is that the Motor is an electric device that converts electrical energy into mechanical energy. The generator is vice versa of that motor. It converts mechanical energy into electrical energy.
How a motor works physics?
An electric motor converts electrical energy into physical movement. Electric motors generate magnetic fields with electric current through a coil. The magnetic field then causes a force with a magnet that causes movement or spinning that runs the motor.
What are the uses of motors and generators?
A motor–generator (an M–G set) is a device for converting electrical power to another form. Motor–generator sets are used to convert frequency, voltage, or phase of power. They may also be used to isolate electrical loads from the electrical power supply line.
What are the importance of motors and generators in our everyday lives?
They provide a good source of backup power for residential, commercial, and industrial applications. They are also extensively used at construction sites.
How does a generator produce electricity physics?
An electric generator is a device that produces electricity through electromagnetic induction. Electromagnetic induction is the process of generating electric current with a magnetic field. Generators may produce either alternating or direct current, but they all change kinetic energy to electrical energy.
What is the basic purpose of a generator?
In electricity generation, a generator is a device that converts motive power (mechanical energy) into electrical power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks.
What is the main difference between a generator and a motor?
An electric motor converts electrical energy into mechanical or kinetic energy, whereas the electric generator transforms the electric energy into mechanical/kinetic energy.
What does a generator do?
An electric generator is a device that converts mechanical energy obtained from an external source into electrical energy as the output. It is important to understand that a generator does not actually ‘create’ electrical energy.
What is the generator effect?
The GENERATOR EFFECT demonstrates that a voltage, and hence a current, can be generated by plunging a coil of wire into and out of a strong magnet. The changing magnetic field within the loops of wire creates an electric field that pushes the electrons in the wire through the lamp, briefly lighting it.
How are a generator and a motor related?
Both motors and generators can be explained in terms of a coil that rotates in a magnetic field. In a generator the coil is attached to an external circuit that is turned, resulting in a changing flux that induces an emf.
What is the working principle of a generator?
The working principle of generator is based on electromagnetic induction. The shaft of an electric motor is driven by a magnetic force which is developed between the armature and field. The shaft of an electric generator is connected to the rotor which is driven by a mechanical force.
How are magnetic fields produced in a generator?
In practice, (and unlike the diagrams we have drawn), generators and DC motors often have a high permeability core inside the coil, so that large magnetic fields are produced by modest currents. This is shown at left in the figure below in which the stators (the magnets which are stat-ionary) are permanent magnets.
How does an electric motor produce rotational motion?
Their structure is a coil mounted on an axel within a magnetic field. An electric motor is used to produce rotational motion from an electrical supply. In a motor an electric current is passed through the coil. The coil then creates a magnetic field that interacts with the already existing magnetic field. This interaction forces the coil to rotate.
