Mell What is the use of circle diagram of induction motor?
A circle diagram is a graphical representation of the performance of an electrical machine. It is commonly used to illustrate the performance of transformers, alternators, synchronous motors, and induction motors.
What is meant by circle diagram of an induction motor what information can be obtained from the circle diagram?
The Circle Diagram of an Induction motor is very useful to study its performance under all operating conditions. It is the diagrammatic representation of the performance of the induction motor. The circle diagram provides information about the power output, losses, and the efficiency of the induction motor.
What is the advantage of circle diagram?
Other than the main advantage that circle graphs are able to show total percentages for each category that you’re displaying, it’s also visually appealing. The cons of circle graphs is that it’s hard to compare two sets of data with each other. The numerical data that you display isn’t very exact.
What is meant by circle diagram?
heyland in 1894 and B.A. Behrend in 1895, the circle diagram is the graphical representation of the performance of the electrical machine drawn in terms of the locus of the machine’s input voltage and current. The circle diagram can be drawn for alternators, synchronous motors, transformers, induction motors.
What are the different types of circle diagram?
The circular charting shapes include circular motion, circle, trapezoid ring, basic loop, divergent circle, divergent blocks, highlight circle, variable radian, bevel style circle, circle pie, Venn circle, among others.
What are power circle diagram?
Power circle diagrams drawn for either sending or receiving ends of a transmission line do not have a common centre for the voltage circles, nor are the power axes within the same semicircle. Es, Is — Sending-end line voltage and current. Er, lr — Receiving-end line voltage and current.
What is a circle diagram called?
A Venn diagram is an illustration that uses circles to show the relationships among things or finite groups of things. Circles that overlap have a commonality while circles that do not overlap do not share those traits. Venn diagrams help to visually represent the similarities and differences between two concepts.
What do you mean by circle diagram?
A circular diagram is a graphical representation used in economics to represent the financial transactions in an economy. The basic circular diagram consists of two segments that dictate revenue, investment, and output: flow of physical things (goods or labour) and flow of money (what pays for physical things).
How to draw circle diagram of induction motor?
To draw a circle diagram like the one below: The no-load current and the no load angle calculated from no load test is plotted. This is shown by the line OA, where Ɵ 0 is the no load power factor angle. The short circuit current and the angle obtained from block rotor test is plotted. This is shown by the line OC and the angle is shown by Ɵ B.
Which is the output line of an induction motor?
The line AC is called the power line. By using the scale for power conversion that we have taken in the circle diagram, we can get the output power if we move vertically above the line AC to the periphery of the circle. The output power is given by the line MB. The total copper loss is given by the line GM.
How is the stator current of an induction motor calculated?
The stator current is calculated from the equivalent circuit of the induction motor which we get from the two tests. That current is plotted in the circle diagram according to the scale with touching origin and a point in the circle diagram which is shown by B.
How is induction motor used in no load test?
In no load test, the induction motor is run at no load and by two watt meter method, its total power consumed is calculated which is composed of no load losses only. Slip is assumed to be zero. From here no load current and the angle between voltage and current required for drawing circle diagram is calculated.
