    I have written this science research paper to help people understand more about the electric motors and their operation. The electric motor transforms electrical energy into mechanical energy, which in turn makes motion possible. To better understand electric motors, one should first understand the basics of electric motors operation, electromagnetics. One can create an electromagnet by running an electric current through a wire which in turn will create a magnetic field. An electromagnet may

    MOTOR BASICS BASIC COMPONENTS * Armature - Sometimes called a rotor. This is the part that spins. The armature can be either a permanent magnet or an electromagnet. * Stator - This is the part that doesn't move. The rotor spins in the magnetic field contained in the stator. HOW WORKS A MOTOR? The force that that turns the armature comes from the magnetic field of the armature trying to line up with the external magnetic field of the stator. This force is called torque. This

  • What Are The Advantages And Disadvantages Of Electric Motor

    776 Words  | 2 Pages

    Electric motors are the most common device for converting electrical energy into mechanical power. According to the laws of physics "whenever a current carrying conductor is placed in a magnetic field, it experiences a mechanical force"[1]. The Armature which is simply a coil of wires is places between two magnets. When the current is supplied through the armature an electromagnetic force is induced on it according to the Lorentz law so the coil will start to rotate. As the armature is connected

  • Rolling Element Bearings In Electric Motors

    1319 Words  | 3 Pages

    Rolling-element bearings in electric motors support and locate the rotor, maintain a small and consistent air gap between the rotor and stator, and transfer loads from the shaft to the motor frame. The correct bearings for an application let a motor run efficiently across its design speed range, minimize friction and power loss, produce little noise, and have a long service life. On the other hand, bearings can be quickly ruined when a motor is used improperly. For example, the deep-groove ball

    automobiles and other motor-run things. Electric motors also conserve energy and isn't as harmful as a diesel engine or motor engine. Electric motors date back all the way in the 1800's when Thomas Davenport built the first real working electric motor. He used a spinning wheel technique and levers that move back and forth repeatedly. His work ended up being used to move trolleys, but not till 50 years after his death. The picture on the right is an example on how his electric motor looked like. This

    induction ring was the first electric transformer. In a second series of experiments in September he discovered magneto-electric induction: the production of a steady electric current. To do this, Faraday attached two wires through a sliding contact to a copper disc. By rotating the disc between the poles of a horseshoe magnet he obtained a continuous direct current. This was the first generator. From his experiments came devices that led to the modern electric motor, generator and transformer. Faraday

    Synchronous Motor: Supposed in light of the fact that rotor tries to match with the magnetic field in the stator. It has the stator of an induction engine, and the rotor of a dc engine. A synchronous engine is an AC engine, which keeps running at steady speed altered by recurrence of the framework. It requires coordinate current (DC) for excitation and has low beginning torque, and consequently suited for applications that begin with a low load, for example, air compressors, recurrence changes
