What does a Rotating magnetic field do?
The Field which is continuously rotating with a particular axis is known as rotating magnetic field. It will be created in Three phase induction motor's stator. When the supply is given to stator of three induction motor, the flux of each phases (that are displaced by 120 degrees) will interact. Due to this the resultant Field will be rotating Magnetic Field will be Produced.
How linear induction motor work?
The linear induction motor works on the same principle as that of normal induction motor with difference that instead of rotational movement, the rotor moves linearly. If the stator and rotor of the induction motor are made flat then it forms the linear induction motor. The flux produced by the flate stator moves linearly with the synchronous speed from one end to the other. The synchronous speed is given by, v s = 2wf where v s = Linear Synchronous Speed (m/s) w = Width of one pole pitch (m) f = Frequency of supply (Hz) It can be seen that the synchronous speed is independent of number of poles but depends only one width of pole pitch and supply frequency.
What happens if an ac supply is given to dc generator?
AC supplies are not given to DC gennies. A DC gen requires a mechanical prime mover.
What kind of supply is given to schering's bridge?
schering's bridge is used to measure capacitance and dissipation factor of a capacitor. AC voltage is given to the terminals of bridge and bridge is balanced by varying resistance and capacitance in the opposite arm.
Why synchronous motor called double excited motor?
AC and DC supply sources we are given to motor so we are called double excited motor
What will happen of you give AC supply to stator winding of DC generator?
why the supply is given to the stator of dc generator give answer
What will happen when DC supply is given to a bulb?
When a 230 V dc supply is given to a bulb it will glow, because it has just a coil inside.
What happens if 3 phase supply is given to stator and rotor both in a induction motor?
its impossible to give suppy to rotor of an induction motor,because of it a closed path for circulating currents.
In a dc motor the input power is given to stator or rotor?
rotor
What would happen to the bulb if you we give supply from the both sides at the same time?
as both supply is given from same phase then the bulb will glow as normal
What will happen if dc supply is given to shunt dc motor?
It will drawn a large amount of current which can destroy the shunt
What is a money supply?
The total supply of money in circulation in a given country's economy at a given time.
Why does the supply curve shift to the left?
The supply curve shifts to the left when there is a decrease in the quantity of goods or services that producers are willing and able to supply at a given price. This can happen due to factors such as increased production costs, decreased availability of resources, or changes in technology.
What kind of supply is given to the circuit?
ac supply is given and then in the circuit rectifier converts ac to dc
What would propably happen to the value of bauxite if its supply suddenly increased and why?
According to the general rules of supply and demand, the value of any given commodity is inversely proportional to its availability. That is, the more readily available something is, the less valuable it tends to be.
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.
When will there be an increase in supply?
An increase in supply occurs when producers are able and willing to offer more goods or services for sale at a given price. This can happen due to factors such as lower production costs, technological advancements, or an increase in the number of producers entering the market.
