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.
Which of the following are the factor affecting machine design?
Four basic factors that are to be considered while selecting the materials are: availability, cost, mechanical properties, and manufacturing considerations.
What are the factors which are important in design when it comes to the machine used in power system?
Explanation: There are 3 considerations present in the design of the machine. They are cost, durability, compliance with performance criteria as laid down in specifications.
What are the different methods of electrical machine design?
There are popular methods for the thermal analysis of electrical machines. They are computational fluid dynamics (CFD), FEM, and nodal method. Structural design aims to consider the stress and deformation of the machine under the electromagnetic and thermal analyses.
What are the major parts of any machine considered for design?
Machine design focuses on the basic principles of the following three areas: Mechanical behavior includes statics, dynamics, strength of materials, vibrations, reliability, and fatigue. Machine elements are basic mechanical parts of machines.
What is the ratio of factor of safety?
The factor of safety is defined as the ratio of ultimate to working stress (in case of brittle material). The factor of safety may also be defined as the ratio of the resisting force to failure causing force.
What is the machine design?
Machine design is an area of study in which one learns to design machine parts by utilizing its whole knowledge and experience in field of mechanical engineering. OBJECTIVES OF DESIGN. DESIGN FOR STRENGTH- safety is first so part to be designed should strong enough to withstand forces in its service.
How will you classify machine design and explain it?
This is where the fundamentals of machine design come in, and they can be broken down into three categories, Adaptive Design, Developmental Design and New Design.
What is the most important consideration in machine design?
Cost: Cost has always been the major factor of consideration while designing the machine elements or machine and in this age of competition it has become more important.
What is the first step of design procedure?
Discovery is the first step of the design process, where teams work together to develop an understanding of the problem they are trying to solve, and define the path they will take to explore solutions. It culminates in the communication of a vision – a concise mantra of the team’s conclusion.
Which is the major consideration to develop a good electric machine design?
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 are the types of electrical machines?
The electric machines are of three main types, transformer, generator, and motor.
What is computer aided electrical design?
Introduction Computer Aided Design (CAD) involves usage of computer systems to create, modify, analyse or optimize a given project. … For electrical and electronic designs, the parameters involved may be so many to calculate by hand, hence the need for computer-based iterations.
