brake test on three phase squirrel cage induction motor

The three phase induction motor is the most widely used electrical motor. Almost 80% of the mechanical power used by industries is provided by three phase induction motors because of its simple and rugged construction, low cost, good operating characteristics, absence of commutator and good speed regulation. In three phase induction motor the power is transferred from stator to rotor winding through induction. The Induction motor is also called a synchronous motor as it runs at a speed ....etc

You crave simplicity and fast heating electric furnaces, but long for a more flexible control of temperature? Perhaps your favorite TV chef has won you on cooking with gas, but the thought of break your kitchen to put in gas line leaves you cold. Maybe you have a gas stove, but wish you could turn the burner without dehydrating the flame. What camp you are when it comes to cleaning, chances are you would like only to throw them for a new FlatTop from glass and ceramic ranges.
But there is another option. Induction hobs boast speed, superior cof ....etc

principle of operation of induction generator ppt

An induction generator or asynchronous generator is a type of alternating current (AC) electrical generator that uses the principles of induction motors to produce power. Induction generators operate by mechanically turning their rotors faster than synchronous speed. A regular AC asynchronous motor usually can be used as a generator, without any internal modifications. Induction generators are useful in applications such as mini hydro power plants, wind turbines, or in reducing high-pressure ga ....etc

Aim
To conduct load test on three-phase squirrel cage induction motor.
Apparatus Required
Precaution
The motor should be started without any load.
Procedure
1) Connections are given as per the circuit diagram.
2) The TPSTS is closed and the motor is started using star-delta starter to run at rated speed.
3) At no load the speed, current, voltage and power are noted down.
4) By applying the load gradually with the help of spring balance and brake drum arrangements.
5) The speed, current, volta ....etc

AIM:
To draw the performance characteristics of 3-phase squirrel cage induction motor by conducting load test.
THEORY:
A 3-phase induction motor consists of stator and rotor with the other associated parts. In the stator, a 3-phase winding is provided. The windings of the three phase are displaced in space by 120 .A 3-phase current is fed to the 3-phase winding. These windings produce a resultant magnetic flux and it rotates in space like a solid magnetic poles being rotated magnetically. ....etc
