What are the factors which influence the choice of specific magnetic and electric loadings of a synchronous machine?
The magnetic loading and electrical loading is most important parameter in the electrical machine. the electrical machine's torque is define as T=winding factor*electrical loading*magnetic loading*rotor volume You can see that the magnetic loading can decide electrical machines volume so this parameter is important.
How the direction can change of Permanent split capacitor motor?
A single speed permanent split capacitor AC induction motor has two separate pairs of series wound stator windings arranged at right angles to each other around the central rotor. The main run winding is connected directly to the AC power source while the secondary start winding is connected to the same source with a capacitor in series with it. The capacitor causes an electrical phase shift to the power in the start winding relative to the run winding, to produce a rotating magnetic field around the rotor which can start it turning. Since the capacitor remains in the circuit while the motor is running it's called a permanent split capacitor design.
What is the direction of the magnetic field if the current is directed upward or downward?
The direction of the magnetic field is counterclockwise or clockwise. For a current flowing in a wire you can use the "left hand rule" If you take your left hand and have the thumb point in direction of electron flow in the wire, the fingers wrapped around the wire will show the direction of the magnetic field by the direction the fingers are pointed..
Region around a magnet in which magnetic force can act?
Magnetic freild
What is produced around a wire that has a current?
Magnetic field.
What spinning particle creates a magnetic field?
An electron is a spinning particle that creates a magnetic field. The spinning motion of the electron generates a magnetic dipole moment, resulting in the creation of a magnetic field around the electron.
How magnetic moment originate from motion of electron?
Electrons revolve around the nucleus. A revolving electron is equivalent to a current loop. Hence, it produces a magnetic moment.
What creates a magnetic charge within an atom?
The electron spin, and the electrons' revolution around the nucleus.
Is the Aurora Borealis a star?
no the Aurora Borealis is not a star. it is more commonly called the "northern Lights" the effect is when the magnetic field around the earth deflects the radiation from the sun. that is how the "light" effect is caused.
What is induction motor in physics?
An induction motor consists of a rotor winding and stator winding. Rotor windings are short circuited and stator winding are given electrical AC supply .Now lets do the physics behind it . As the current starts to flow in the stator winding , magnetic flux start to produce around it . due to it's alternating nature that flux varies and according to farady law emf is induced in the rotor winding .Since the rotor winding is short circuited the current circulates in it .And when a current carrying conductor is placed in magnetic field it experiances a force and hence if start to rotate.
How magnetic moment of electron is associated with angular momentum of electron?
magnetic moment of a particle is due to its motion around some other orbits or about its own orbit i.e due to its orbital angular momentum or its spin angular momentum.
What causes the magnetosphere to exist?
The magnetosphere exists due to Earth's magnetic field, which is generated by the movement of molten iron in its outer core. This magnetic field extends out into space, forming a protective shield around the Earth that deflects charged particles from the solar wind.
What two kinds of electron motion are important in determining the magnetic property of a material?
The two main types of electron motion that are important in determining the magnetic property of a material are spin motion and orbital motion. Spin motion refers to the intrinsic angular momentum of an electron, giving rise to its magnetic moment, while orbital motion refers to the movement of electrons around the nucleus within an atom, contributing to the overall magnetic behavior of the material.
Why do electrons behave like tiny magnets?
Electrons behave like tiny magnets because they have a property known as spin. This spin generates a magnetic field around the electron, giving it magnetic properties. When electrons are in motion, their spin causes them to act like small magnets, aligning with an external magnetic field.
How do you reverse a 1 phase motor?
turn it around A split phase induction motor has two sets of coils and a centrifugal start switch. The start winding is in series with the start switch. The start winding provides a rotating magnetic field in one direction enabling the motor to start. The motor can be reversed by reversing the connections of either the start winding or the run winding but not both.
What does a magnetic field for a toroid look like?
A magnetic field for a toroid is typically concentrated within the coil, circling around the winding. Inside the toroid, the magnetic field lines are close together and form closed loops. Outside the toroid, the magnetic field is very weak and essentially negligible.
What do the parts of an electromagnet do?
An electromagnet requires only two parts, a core of ferro-magnetic material and wires winding around it. The wires magnetize the core when current flows through them, and the core then creates the magnetic field which the electromagnet is intended to produce.
