The space between the stator and the rotor is called the air gap. The stator is the static part and the rotor is the moving part. The stator is made up of thin sheets of heat-treated magnetic steel or silicon steel to minimize losses due to eddy currents and hysteresis. These sheets are shaped like a ring with internal grooves (front view) so that the windings can be housed, which in turn, when in operation, must create a magnetic field in the stator. The rotor is also made up of thin sheets of heat-treated magnetic steel, also shaped like a ring (front view) and with the windings housed longitudinally. There are two types of induction motor: Three-phase induction motor, short-circuited rotor (squirrel cage type): In which the rotor is made up of bars of conductive material that are located around the set of rotor sheets, short-circuited by metal rings at the ends. (Model shown in the video). Three-phase induction motor, wound rotor: In which the rotor is composed of windings distributed around the rotor plate assembly. Construction: The induction motor is the simplest motor to build. The stator and rotor are assembled together, with a common axis to the “rings” that compose them. The stator consists of a three-phase winding distributed uniformly around the body of the machine, so that the magnetic flux resulting from the application of voltage to the stator winding produces a particularly sinusoidal waveform. The electromagnetic wave produced by the winding is a sinusoidal function of space and time. How the test is performed: Step 1 - Knowing that the three-phase motor is composed of 3 internal coils, you will first need a multimeter on the ohm scale to identify these coils. Once identified, they are marked as 1, 2 and 3. Step 2 - You will interconnect two coils in series and apply a voltage of 220V to the ends. On the coil that was not used, you will place the multimeter on the voltage scale. If voltage appears on this coil, it is because the connection of the two coils in series is correct (correct polarity). If no voltage appears, reverse the connection of either of the two coils that are in series and test again. Mark the input and output numbers of the two coils. Step 3 - Replace one of the two coils that are in series with the coil that was used to detect the induced voltage. Repeat the tests from step 2 and mark the input and output of the last coil. Step 4 - Now that everything is marked and the coils are identified, just connect the motor and energize it. ????
