What is the other name of induction motor?

asynchronous motor
An induction motor (also known as an asynchronous motor) is a commonly used AC electric motor. In an induction motor, the electric current in the rotor needed to produce torque is obtained via electromagnetic induction from the rotating magnetic field of the stator winding.

Which of the following test of induction motor is equivalent to short circuit test?

blocked rotor test
The blocked rotor test of an induction motor is similar to the short circuit test of a transformer. The shaft of the motor is locked so that it cannot move and the rotor winding is short-circuited.

What is load test of induction motor?

The load test on induction motor is performed to compute its complete performance i.e. torque, slip, efficiency, power factor etc. During this test, the motor is operated at rated voltage.

What are the different types of induction motors?

Starting. There are three basic types of small induction motors: split-phase single-phase, shaded-pole single-phase, and polyphase. In two-pole single-phase motors, the torque goes to zero at 100\% slip (zero speed), so these require alterations to the stator such as shaded-poles to provide starting torque.

How do you test a motor for a short circuit?

To test your motor for short to ground, you’ll need to set the multimeter to ohms and disconnect the motor from its power source. Then inspect each wire and look for infinite readings. Alternatively, if you get a reading of 0, you might have a cable issue.

What is determined from short circuit test?

The purpose of a short-circuit test is to determine the series branch parameters of the equivalent circuit of a transformer.

Why do we need short circuit test in transformer?

What is the use of DC test on induction motor testing?

To calculate the resistance (R2) of the rotor we should have the idea of R1 (stator resistance) so that it can subtract from the total resistance. The test is done on the motor to find the resistance (R1) of the stator is named as dc test of induction motor.

What is short circuit test in motors?

It is also known as short circuit test, locked rotor test or stalled torque test. From this test, short circuit current at normal voltage, power factor on short circuit, total leakage reactance, and starting torque of the motor can be found. The test is conducted at low voltage because if the applied voltage was normal voltage…

What is the blocked rotor test of an induction motor?

Blocked Rotor Test of an Induction Motor. The Blocked Rotor Test of an induction motor is similar to the short circuit test of a transformer. In this test, the shaft of the motor is locked so that it cannot move and the rotor winding is short circuited. In the slip ring motor, the rotor winding is short circuited through the slip rings.

What is no load test of three-phase induction motor theory?

Experiment (3) No load Test of Three-phase Induction Motor Theory: Ic The no load test is similar to the open circuit test on a transformer. It is performed to obtain the magnetizing branch parameters (shunt parameters) in the induction machine equivalent circuit.

What are the different types of small induction motors?

There are three basic types of competing small induction motors: single-phase, split-phase and shaded-pole types and small polyphase motors. In two-pole single-phase motors, the torque goes to zero at 100\% slip (zero speed), so these require alterations to the stator such as shaded-poles to provide starting torque.
