    1493 Words  | 6 Pages

    energy. In today’s life, electric motors have numerous applications including in homes, commercial buildings, and manufacturing industries. An electric motor works on the principle of Ampere’s law which states when a wire is carrying an electric current, it generates magnetic field around itself. In other words, an electric motor is able to generate motion by use of magnets and therefore its whole operation is about magnets & magnetism. Electric motors have been in use since 1800s and their efficiencies

  • Essay On Induction Motor

    754 Words  | 4 Pages

    The Induction Motor Induction Motor applies alternating current and basically made up of two parts(8), a stator and a rotor. A stator remains stationary, while it rotates the rotor with the help of electromagnets. Induction motors are not just long-lasting, but also easy to maintain and inexpensive to run. In 1880s, Galileo Ferrari and Tesla were working on the same project of induction motor, but separately. None of them knew about each other’s findings and both of them submitted it in the year

  • Disadvantages Of Dc Motors

    1102 Words  | 5 Pages

    2.4 DC Motors Fig. 2.4.1 DC Motor DC motor is an electrical machine that converts the direct current electrical power into mechanical power. Most of the DC motors depends on the forces produced by magnetic fields. All types of DC motors have some internal mechanism, either electromechanical or electronics, to periodically change the direction of current flow in part of the motor. Most types produce rotary motion; a linear motor directly produces force and motion in a straight line

    a static device that works on Faraday’s law of electromagnetic induction and it is used to transfer electrical energy from one circuit to another or in other words it is a device which is used for decreasing or increasing the voltage of an alternating current. Basically there are two types of transformer i.e. step up and step down transformer but in general transformers are classified in different ways, depending upon their use, purpose, construction etc. Therefore transformer sizing helps us to

  • Characteristics Of An Antenna

    824 Words  | 4 Pages

    In electronics, an antenna is an electrical apparatus that will modify electric power to radio waves or vice versa. It is often being use as a transmitter and receiver. Antenna transmitter will send an alternating current that is in radio frequency to radiate the electromagnetic energy to electromagnetic waves. Antenna receiver will receive the power of an electromagnetic wave to produce a tiny voltage at the terminal to be amplified. The shape and size of the antenna’s structure will decide how

  • Bldc Motor Advantages And Disadvantages

    in induction motors. BLDC motors come in single-phase, 2-phase and 3-phase configurations. Corresponding to its type, the stator has the same number of windings. Out of these, 3-phase motors are the most popular and widely used. Brushless Direct Current (BLDC) motors are one of the motor types rapidly gaining popularity. BLDC motors are used in industries such as Appliances, Automotive, Aerospace, Consumer, Medical, Industrial Automation Equipment and Instrumentation. As the name implies, BLDC

  • Essay On Capacitors

    2514 Words  | 11 Pages

    INTRODUCTION TO CAPACITOR Capacitors are widely known as an electrical component which is mostly found in power supplies because of their capacity to store energy. They are two terminal electrical elements consisting of two conductor plates which are separated by a dielectric material or insulator, i.e., poor conductor material. They are also referred as condenser they have an ability to store energy in the form of electric charge which produces a static voltage across its plates. The capacitor consists

  • 3 Phase Induction Motor

    varying magnetic field emf are induced which are called induced emf, if inductor circuit are closed, currents are also induced which is called induced current. As the rotor winding in an induction motor are either closed through an external resistance or directly shorted by end ring, and cut the stator rotating magnetic field, an emf is induced in the rotor copper bar and due to this emf, a current flow through the rotor

  • Electric Motors Report

    1630 Words  | 7 Pages

    1 INTRODUCTION Electric motors are widely classified into two distinct categories: AC (Alternating Current) and DC (Direct Current). DC is distinguished from AC with its ability to flow in one direction. There are different kinds of DC motors but they all work on the same principle [1]. Electric motors are a means of converting energy. There is a wide range of DC applications ranging from small to big applications in the industry. It is of vital importance for engineers to know motors so that they

    physics, but also how people lived their lives. Through his discoveries in commercial electricity, Tesla changed the world in the 20th century and molded the way technology was used. His contributions to electricity, most notably the alternative-current (AC) electrical system, are still widely-used today in contemporary society. Most people today have heard the Tesla name through the renowned Tesla motors, but few understand the impact that Nikola Tesla left in modern science and technology. Tesla

    industrial applications such as production lines, remote control airplanes, automatic navigation systems and many other applications. There are two types of positional rotation servo motor which are DC servo motor that is controlled by DC, and Alternating Current (AC) servo motor which is controlled by AC. The servo motor “internal” positional feedback consists of either encoder feedback or voltage feedback. The built-in encoder inside the servo motor provides a pulse signal that is processed by the
