cost. 2. Theory Electric Motor is an essential machine in almost all industries for their manufacturing work,having this much importance motor has an issue which is very big in electricity distribution and industrial view point,that is motor draw more current in its starting upto five to six times from its nominal value. This problem is resolve by the use of the device called Electric motor starter. Next section mainly concern tha what is starter. 3. Motor Starter A larger motor require some switching
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
Physics of an Electric Motor An electric motor is a device used to convert electric energy into rotational kinetic energy. There are two different types of electric motors, and each has there own use. The different types are direct current and alternating current motors. Each of these motors will be analyzed in the following. To understand how this motor works, we must understand the relationship between electricity, and magnetism or simply put electromagnetism. Direct electric current in a
7.1 INTRODUCTION TO MOTORS Electric motor is a machine used to convert electrical energy to mechanical energy. In this project we used one DC motor, which is used as a fan that can controlled using android application. Electric motors are extremely important to modern-day life, being used in many different places, e.g., vacuum cleaners, dishwashers, computer printers, fax machines, video cassette recorders, machine tools, printing presses, automobiles, subway systems, sewage treatment
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
Case Report-Siemens Electric Motor Works Group Members: Yang ZOU(Mandy) (5330162) Lin SUN(Chris) (5289426) Abu Naser Lmtiaz (5271713) Wenjun WANG(Sara) (5287925) Binglu WANG(Lucy) (5061742) Executive Summary Siemens Electric Motor Works was the only factory in West Germany to manufacture electrical motors after the World War two. Because of the lower labor rates of its competitors, the management decided to produce low volume
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
our society which was the Electric Motor. The Electric Motor was invented by a blacksmith named Thomas Davenport in 1834. An Electric Motor is used mechanical energy which comes from electrical energy. It is used in almost anything computers, electric cars, ACs. The Electric Motor had the largest impact on society during the 20th century because it lead to many important inventions such as telephones, electric cars, and even founded electricity. The Electric Motor in a phone is a vibrator
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
steam turbines and electric motors. Drives which employ electric motors are called as Electrical Drives. Basically Drive is a combination of various systems combined together for the purpose of motion control. Electrical drives are available with vast range of torque, speed and potential. Can employed electric braking due to which they are having malleable star control components. Previously, Induction and contemporary motors were employed mainly in constant speed drives. DC motor used by variable
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
Electrical motors play an important role in today’s society, from powering domestic appliances like blenders to industrial equipment such as trains. It almost seems impossible to not use an electric motor in our daily lives. In the comfort of our home, electric motors will operate fans, refrigerators, and air conditioners to just name a few. Researchers are constantly looking for new ways to incorporate electrical motors in our lives. Electrical motors function by converting electrical energy
On May 13th, 1930, Jacob Schick, an american inventor and entrepreneur, invented the electric razor. This invention created a way for men and women to dispose of unwanted body hair without accidentally getting cuts, gashes, and other unwanted injuries. This invention would be highly regarded as an important invention in modern history. The idea of the electric razor came to Jacob Schick while recovering from an injury he got while doing a gold expedition in Alaska and British Columbia. Jacob found

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

Because these conversion devices always used some energy in the process of linear to rotary motion, Tesla’s idea of a commutator-less motor seemed to Poschl that Tesla would be cheating Nature.” (TESLA) Poschl intended that what he said to Tesla would change his resolve from what
controlled is the speed of the DC motor. The speed of the DC motor is defined as [5]: EMBED (1.1) Where N = Speed V = Supply voltage Ia = Armature current Ra = Armature resistance ( = Magnetic flux 7 In reality, the flux and Ra are hard to control. The only parameter that can adjust is the voltage V. As V is increased, the speed of the DC motor also increased. Thus, the speed of the DC motor is directly proportional to
Life Cycle Cost: The life cycle cost(LCC) of an induction motor involves the total purchasing price , installation and operating cost, maintenance and disposal cost of that motor. When used as a tool to compare design alternatives or possible repair, the LCC method show the most effective solution in terms of cost in the range of necessary data is available The constituents of the life cycle cost analysis typically consist initial costs, installation and operation costs, refurbishment and disposal
