Frog Leg Winding DefinitionA frog leg winding is a combination of a multiplex wave and a simplex lap winding in the same slots. It retains the advantages of both lap windings and wave windings without their inherent disadvantages.Lap and wave windings each have an equal number of parallel paths, which are connected to the same commutator.The frog-leg winding has as many parallel paths as duplex lap windings because the simplex lap winding portion supplies ‘P’ number of parallel paths and the mul

DC Generator Types Permanent Magnet DC Generators – Field coils excited by permanent magnets Separately Excited DC Generators – Field coils excited by some external source Self Excited DC Generators – Field coils excited by the generator itselfSelf Excited GeneratorA self-excited DC generator uses its own output to power its field coils, which can be arranged as series, shunt, or compound wound.The three types of self-excited DC generators are: Series Wound Generators Shunt Wound Generators Comp

Definition of Synchronous MotorsSynchronous motors are electric motors that rotate at a speed directly proportional to the frequency of the supply current.Non Excited Synchronous MotorsThese motors use external magnetic fields to magnetize a steel rotor, achieving synchronization without additional electrical excitation.Hysteresis and Reluctance MotorsTypes of non-excited synchronous motors that use different principles (hysteresis losses and magnetic reluctance) to achieve and maintain synchron

What is are the Types of Single Phase Induction Motors ?Single phase induction motor definitionA single-phase induction motor is an electric motor that operates in a single AC phase and requires additional mechanisms to initiate rotation.According to the extra flux single-phase induction motor can be divided into Split phase induction motor Capacitance starts induction motor Capacitor start Capacitor run induction motor Permanent shunt capacitor (PSC) motor Shaded pole induction motorSeparate ph

What are the Types of Transformers Windings?Types of Transformers Core type transformers have windings on outer limbs Shell type transformers have windings on inner limbsMainly there are two types of transformer Core type transformer Shell type transformerTypes of Winding used for Core Type TransformerCylindrical WindingsThese windings are layered type and uses a rectangular or round conductor shown in Fig.(a) and (b). The conductors are wound on flat sides shown in Fig.(c) and wound on the rib

What are the Types of Electrical Machines?Electrical Machines OverviewElectrical machines are devices like transformers, generators, and motors that either convert electricity to mechanical power or vice versa.TransformersA transformer transfers electrical energy between two circuits without changing the frequency, crucial for regulating voltage levels in power distribution.Transformers Types Step up transformer Step down transformerGeneratorsGenerators convert mechanical energy to electrical en

Battery DefinitionA battery is defined as a device that stores and provides electrical energy through chemical reactions, classified into primary and secondary types.Types of Battery Primary Batteries Secondary BatteriesPrimary BatteriesPrimary batteries, such as zinc-carbon and alkaline, are non-rechargeable and used in devices like clocks and remote controls.Secondary BatteriesSecondary batteries, like lithium-ion and lead-acid, are rechargeable and used in devices like mobile phones and elect

Lamp DefinitionA lamp is defined as a device that produces artificial light for uses such as visibility, decoration, and signaling.How the lamp works Electricity: Electricity is the flow of electrons through a conductor. When electricity passes through a lamp’s filament, gas, or semiconductor, it causes them to emit photons (light particles). Gas: Gas is a state of matter that consists of molecules that are free to move. When gas is heated or exposed to an electric current, it produces light by
