What is 2 pole and 4 pole generators?
Both 2 pole and 4 pole generators are machines which produce electricity. Standard 2 pole versions are cylindrical while 4 pole versions use squirrel cage rotors.
What is the current carrying capacity per pole of 3.5 core 300 sq mm xlpe cable?
according to manufacturers data sheet 325amps ,but plz tell me how to calculate current carrying capacity of a cable.
Describe a double pole single throw relay with a 24 V coil And how does it work?
Double pole single throw relay de-energized, with two separate sets of contacts open. Apply 24 volts to coil terminals, coil steel core magnetizes and pulls hinged armature towards it. The two contacts attached to hinged armature make contact with the two stationary contacts. The double pole relay has now two separate sets of closed contacts.
What is leading pole tip?
The pole tip which is met first during rotation by armature conductors is known as leading pole tip
How many poles as salient pole rotor?
'Salient' means 'sticking out', so if the pole sticks up from the rotor shaft, then it is a salient pole machine.
What is function of pole core?
blah!blah!blah!
Is the geographic North Pole is also called the magnetic North Pole?
no, the magnetic north pole is determined by the molten iron core, and changes.
Why does the north pole of a compass point towards the earth's north magnetic pole?
The center of the earth has iron core
The lines of magnetic force generated by the fluid motions of the earths core result in the formation of what?
the North Pole and the South Pole
Where would it be easiest to drill though Earth?
Through the center? Impossible anywhere, since the core of the Earth is molten iron. The shortest PATH would be from pole to pole, but you still have the problem of the molten iron flowing through the core.
Why is the pole shoe extended beyond the pole core?
Extending the pole shoe beyond the pole core helps to enhance the electromagnetic flux distribution and improve the performance of the electric machine by reducing losses and increasing efficiency. It also provides better support for the winding insulation and helps to reduce the magnetic leakage.
Is it possible to dig a hole from north pole to south pole of earth?
Only if you could withstand the immense heat of the inner core of the Earth's center !
Is the Earth's core spinning in the opposite direction?
No, the Earth's core is not spinning in the opposite direction. The core of the Earth rotates in the same direction as the rest of the planet, which is counterclockwise when viewed from above the North Pole.
What is the middle of the earth is called?
The middle of the Earth is called the Earth's core. It consists of the inner core and outer core, which are primarily composed of iron and nickel. The core is extremely hot and plays a critical role in generating the Earth's magnetic field.
Why is it that the Earth's geographic north pole is actually a magnetic south pole?
The Earth's geographic north pole is actually a magnetic south pole because the Earth's magnetic field is generated by the movement of molten iron in its outer core. This movement creates a magnetic field that aligns with the geographic north pole, causing it to act as a magnetic south pole.
What causes magnetic pole?
The Earth's magnetic field is believed to be generated by electric currents in the conductive material of its core, created by convection currents due to heat escaping from the core.
What charicteristic of the earth makes it a giant magnet?
The Earth's magnetic field is generated by the movement of molten iron in its outer core. This movement creates electric currents, which in turn generate a magnetic field around the planet. This magnetic field acts as a giant magnet, with one pole near the geographic North Pole and the other near the South Pole.
