What is the relationship between an induction motor and transformer?
In an induction motor, power is supplied to the rotor using a changing magnetic flux i.e. without any true conductive contact. Similarly, in a transformer, the power is transferred from the primary coil to the secondry one using a varying magnetic flux and the plates have no physical linkage. Hence, the similarity between an induction motor and a transformer is very basic i.e. they both use the phenomenon of electromagnetic induction to transfer power from one part to another.
Disadvantages of 3 phase induction motor?
One of the disadvantages of the 3 phase induction motor is that it requires a three wire supply. The other disadvantage is that the 3 phase induction motors have poor starting torque and high have in the rush currents.
What kind of motor is used either on ac or dc supplies?
single phase induction motor
What is the type of motor used in running a lathe spindle?
230V/1Ph/50Hz 1HP (0.75 kW)Motor Capacitor start induction motor ( single phase)
What is the load side of a transformer?
The load side of a transformer feeds the device, such as a light or motor. It is the output of the transformer. The input, or line side, provides the voltage that is to be transformed, either up or down, to supply the load side.AnswerA transformer's primary winding is connected to the supply voltage, and the secondary winding is connected to the load.
How are the two circuits of an induction motor similar to the circuit of a transformer?
They are magnetically coupled--a current in one circuit induces a current in the other one in both a transformer and an induction motor.

What is a slip in electricity?
it is the difference between the synchronous and asynchronous speed of a induction motor
Why the no-load current of an induction motor is high compared to a transformer?
Because of the presence of the air-gap between stator and rotor in motor the magnetization current is much higher than that of a transformer in addition to the friction and windage losses due to the rotation of the rotor.
Why induction motor is also called short circuit transformer?
Like transformer induction motor has stator winding(Primary winding) and rotor winding(Secondary winding) separated by an airgap.Rotor winding(generally Al bars) are short circuited at the end to produce torque for the rotation.Hence the name short circuited transformer.
What is an inducting motor?
induction motor has two control system one is stator control another rotor control And it comes under the category of asynchronous motors. The term induction is because the rotor of an a.c motor does not receive the electric power through conduction but by induction same as the secondary of the transformer receives the power from primary. And so an induction motor can also be called as a rotating transformer i.e. one in which primary is stationary and secondary is free to rotate.
What is the difference between vector control and Stator Voltage control method of induction motor?
I need the answer of this question plz!!
Why dc motor is not named as conduction motor?
In dc motors, the electric power is conducted directly to the armature (i.e., rotating part) through brushes & commutator. Hence, in this sense a dc motor can be called as a Conduction motor. However, in ac motors, the rotor does not receive any electric power by conduction but by induction in exactly the same way as the secondary of a two winding transformer receives its power from the primary. That is why such motors are called as Induction motors. An induction motor can be treated as a rotating transformer i.e., one in which primary winding is stationary but secondary is free to rotate.
Difference between induction motor and induction generator?
in case of induction motor the rotor speed is less than synchronous speed giving positive slip but in case of generator the rptor speed is greater than synchronous speed giving negative slip.......
Why less current increases in transformer than in induction motor when load is increase?
The current flowing through a transformer's secondary is the current drawn by the load, so it will be exactly the same as the current flowing through your induction motor -assuming that is the load. Don't really understand the point of your question!
What should be the maximum difference between two phases in three phase induction motor at full load?
120 degrees
What are the different types of induction motors?
