What is electrical machine and its types?
The electric machines are of three main types, transformer, generator, and motor. Electrical Transformer: In the transformer, both input and output are electrical power. Electrical Generator: In a generator, the input is mechanical power and the output is electrical power.
What is electric machine design?
The basic design of an electrical machine involves the dimensioning of the magnetic circuit, electrical circuit, insulation system etc., and is carried out by applying analytical equations. A designer is generally confronted with a number of problems for which there may not be one. solution, but many solutions.
What are the affecting the design of electrical machine?
Major considerations in Electrical Machine Design – Electrical Engineering Materials – Space factor – Choice of Specific Electrical and Magnetic loadings – Thermal considerations – Heat flow – Temperature rise – Rating of machines – Standard specifications.
What is the basic of electrical engineering?
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism.
What are electric machines used for?
Electric motor‐driven systems used 68% of this total electricity for essential energy intensive industrial processes such as refrigeration, pumps, fans, compressors, materials handling, materials processing, and facility HVAC systems.
What is the importance of electrical machines?
The energy conversion between electrical and mechanical power is performed by the electrical machine in both directions. Electrical machines can be used for different ranges of speed. It can be used as motor particularly in traction, electrical vehicles, etc. or as generators in power station, wind turbines, etc.
How many types of machine are there?
There are six types of simple machines — the inclined plane, the wedge, the screw, the lever, the wheel and axle, and the pulley. These six have specific features and do unique jobs, even though some may work in similar ways.
What are the main design parts of an electric machine?
The basic components of all electromagnetic apparatus are the field and armature windings supported by dielectric or insulation, cooling system and mechanical parts. Therefore, the factors for consideration in the design are, Magnetic circuit or the flux path: Should establish required amount of flux using minimum MMF.
What is space factor in electrical machine design?
The stacking factor (also lamination factor or space factor) is a measure used in electrical transformer design and some other electrical machines. It is the ratio of the effective cross-sectional area of the transformer core to the physical cross-sectional area of the transformer core.
