The Automatic Electric Washer Company and Hurley Machine Corporation both began selling electric washers in 1907 while Maytag offered an electric wringer washer in 1911 In 1947 Bendix offered the first fully automatic washing machine and by 1953 spin dry machines overtook the wringer types in popularity
We measure the rate of flow of electricity as an electric current just as we think of the rate of flow of water in a river as the river current The letter used to represent current in an equation is I Electric current is measured in Amperes shortened to Amps or simply the letter A A current of 2 Amps can be written as 2A
A hybrid engine and electric motors combined ability to do work in terms of horsepower torque or efficiency Hybrid power source The source of power in a hybrid vehicle gas/electric plug in
Capacitance The amount of electrical energy stored for a given electric potential Chord or Pitch Factor kp The factor by which short pitching a coil reduces the back Cogging Torque Magnetic interaction between stator and rotor resulting in undesired machine operation such as jerkiness Coil Set of series connected turns Coil Pitch or Span The number of tooth pitches which
Electric machines can have multiple pole pairs Multiple pole machines usually provide more efficient magnetic circuits and smoother torque characteristics Commutation; The connection to the moving coil in the basic machine shown above is made via carbon brushes bearing on a pair of slip rings one connected to each end of the coil
Scope In this standard the term electrical includes both electrical and electronic equipment Requirements that apply only to electronic equipment are so identified The general terms machine and machinery as used throughout this standard mean industrial machinery See Annex C for examples of industrial machines covered by this standard
Electric Power Electricity the flow of electrical power is a secondary energy source generated by the conversion of primary sources of energy like fossil nuclear wind or solar Keeping the power flowing to American homes and businesses is a critical necessity for everyday life and economic vitality
The electrons in the atom are where electricity gets its name In some elements there are electrons on the outside of the atom that when a force is applied can come loose and move to another atom When a bunch of atoms are together and electrons are moving from one atom to the other in the same direction this is called electricity

Electrical Motor Power Velocity and Torque Equations Torque in Imperial units can be calculated as T inlb = P hp 63025 / n 1 where T inlb = torque in lb f P hp = horsepower delivered by the electric motor hp n = revolution per minute rpm Alternatively T ftlb = P hp 5252 / n 1b where T ftlb = torque lb f ft 1 ft lb f = Nm
9 Electrical machines having a power output up to about 750 W may be called machines a small size b medium size c large size d any of the above Ans a 10 Electrical machines having power outputs ranging from a few kW up to approximately 250 kW may be classified as a small size machines b medium size machines c large size
Electricity is a type of energy that comes from the flow of electrical power also known as a charge Electricity is used to power our homes lights and electronics We get electricity from sources like coal energy natural gas and oil Electricity is a secondary source of energy which means it must be made from these items
Rotating electrical machine consists of a stator rotor and the air gap between them Stator and rotor has windings The rotor is installed into the stem and the stem connects to the motor and any other loads The windings are there to carry the electrical current that generates magnetic fields for the electrical load
Electrical circuit A circuit is a closed path that consists of circuit components in which electrons from a voltage or current source can flow If the circuit consists of electric components like a resistor a capacitor an inductor etc then it will be called an Electrical circuit and if the circuit consists of any of the electronic circuit
ELECTRICAL FIELD The region around a charged body in which the charge has an effect ELECTRICITY The flow of electrons from atom to atom in a conductor ELECTROCHEMICAL The relationship of electricity to chemical changes and with the conversions of chemical and electrical energy A battery is an electrochemical device
Electrical abbreviations save time and preserve safety They are used in industries such as automotive and construction plus in anything to do with electrical wiring electronic device repair electronic device manufacturing and electrical work involves significant cost and potential safety risks understanding these abbreviations and acronyms is important for everyone

Electrical engineering sometimes referred to as electrical and electronic engineering is a professional engineering discipline that deals with the study and application of electricity
Overview Working with electricity can be dangerous Engineers electricians and other professionals work with electricity directly including working on overhead lines cable harnesses and circuit assemblies Others such as office workers and sales people work with electricity indirectly and may also be exposed to electrical hazards
The approach of finding torque from the Lorentz force is not practical in many cases and in some cases in the case when calculating the force between two permanent magnets requires some fairly advanced approximations or assumptions In the field of electric machines there is usually a space between the moving surfaces
