Circle diagram of an induction motor is plotted set of lines , arcs, and angles graphically depicting induction motor performance, derived from simple no-load and locked-rotor tests. A motor's "conventional" efficiency was determined based on four losses only: stator and rotor I2R, core loss, and friction and windage. Each of them could be evaluated with acceptable accuracy from tests without shaft load, through use of a circle diagram. Other than this all operational performances of an induction motor can be calculated by circe diagram without actually loading the machine.You can not count the advantages of the circle diagram only when you use it.

What is the difference between vector control and Stator Voltage control method of induction motor?
I need the answer of this question plz!!
Can the position of the rotor and stator in an AC motor be inverted?
In principle they can be exchanged but the result would be a more expensive motor. Imagine an induction motor with the AC applied to the rotor. That would need slip rings and brushes which would need replacing now and again. All the customers would go for the other sort with the AC applied to the stator and a simple squirrel-cage on the rotor.
Explain the principle of operation of a 3 phase induction motor with the help of relevant vector diagrams on no load and load?
The best way to do this is to find the diagrams. Do a quick image search to find the information that you need.
How do you calculate the cost of electricity bill of a 3 phase 125kW induction motor running at 400v 50Hz motor running for 8 hrs condition if 1000w equal to Rs0.238?
To answer this question, i need the power factor of the motor.CommentYou don't need the power factor, as you already know its true power (watts), but you do need to know the efficiency of the motor to determine its input power. You also need to know the cost per kilowatt hour.But you can get a rough idea by multiplying the number of kilowatts, by the time in hours, by the cost per kilowatt hour. For a more accurate answer, you need to divide this by the efficiency of the motor.
What is the advantages of induction motor?
Yet another advantage of electric induction motors is their ability to be connected directly to the AC source. This may not mean much in household uses, but in industrial uses, this can be an important cost saver. Since the basic electric design has graduated into an electronic one over the years, an induction motor is easy to program for its various uses. The initial cost of installing it may be a little high, but it will save money in the long term because of the low maintenance cost and durability of the product. Moreover, it is a flexible design which allows innovations and newer technologies to be incorporated easily without incurring extra costs or necessitating
Do you need starter for 0.5HP three phase induction motor?
You never need a starter for a three-phase motor.
What are the advantages of induction motor?
1. Induction motor has high starting torque, therefore use for operate pump which need high starting torque. 2. Induction motor operate on variable speed. 3. It can be used as generator when speed of motor is higher than synchronous speed.
Does a induction motor need excitation?
The induction motor is the special kind of motor which runs below and above the synchronous speed. which the synchronous motor runs nearly equal the synchronous speed. The operation of synchronous motor runs with dc field excited hence separate dc field current is given to the field circuit. where as the induction motor the field and main field is drawn from the same supply hence no excitation is required. But due to this separate starting mechanism has to be required in case of the single phase induction motor.

How can you reverse the direction of rotation in an induction motor?
A single 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.
Why induction motor speed is always less then synchronous speed?
induction motor never runs at synchronous speed, if it does so there would not be any relative speed between stator flux and rotor and no emf will induce in rotor and we can not apply motor principle as we need current carrying conductor in magnetic field.
