    Explain How Motor Works

    • 411 Words
    • 2 Pages

    are two field magnets on each side coil with wire. These two field magnets always have opposite polarity. On the middle of the motor there is an armature, two commutators and two brushes. When current flow though the two brushes, one of the brushes touches commutator plate 1 and the other brushes touches commutator plate 2. Then the armature A and armature B turn in to field magnets, because when the current flow though iron that coil with wire, it will produce a strong electromagnetic field.…

    • 3 Pages

    1. Existing Knowledge- Based on prior knowledge, the Sulfur and Iron powder can be separated by using a magnet. The known fact is that the Iron particles can be attracted to the Magnet because of the attraction of the opposite charges. The Magnet will pull and attract the Iron and leaving the Sulfur behind. The separation of Sulfur and Iron powder is successfully accomplished because of the property of attraction. Since Iron is a metal, it has a positive charge and one side of the magnet has a…

    AC stands for alternating current which means that the current flows in both directions. So instead of flowing from one source to another, the current can flow from both the source and the recipient to each other. AC voltage is the current that comes from an electrical plug. An advantage of AC voltage is the fact that the power of the voltage can be altered with a transformer. Fig.1 graph showing AC and DC current On the other hand DC voltage stands for direct current. This means that the…

    Final Momentum

    • 337 Words
    • 2 Pages

    Using the data obtained through the Labquest2 computer system, my group and I calculated exactly the initial momentum and kinetic energy, final momentum and kinetic energy, and percent of momentum and kinetic energy that was lost through these collisions. To calculate momentum we used the equation p_i=p_f which expands to m_1 v_1i+m_2 v_2i=m_1 v_1f+m_2 v_2f. We can say that our first hypothesis was accepted since in collisions 1 and 2 the total initial and final momentum was similar values.…

    Turbulence May Spawn Monster Magnetic Fields discusses a lab experiment that aimed to investigate the mysterious and powerful properties of magnetism in space. Magnetic waves are extremely prominent in our universe, which consists of dense galaxy clusters and vast voids of space separating these clusters. While it seems obvious magnetism would be present in the various galaxy clusters, as they are active regions of space, astronomers have also discovered a very strong magnetic presence in the…

    What is a circuit? How do they work? An electric circuit is a kind of path made up of wires that allows the flow of electrons. The circuit has to be made in a circular form, as the electrons must frequently move in a full loop, in which they will return to their original position and then complete the loop again. (“What is an electric circuit?”) The battery or another source of power provides the voltage, or ‘electrical push’, that makes the electrons move through the circuit. When the electrons…

    Rotor and touchdown bearing models Fig. 1 features the case study of the high-speed rotor. The photo was taken after manufacturing of the electric motor part, when the rotor was carried to the laboratory for an experimental modal analysis. During normal operation, the rotor is supported by AMBs. In the dropdown event, the rotor is in contact with touchdown bearings at both ends of the rotor. Fig. 1. Rotor under investigation. In this work, the finite element model of the rotor employs…
