What is meant by electrical machine design? Design may be defined as a creative physical realization of theoretical concepts. Engineering design is application of science, technology and invention to produce machines to perform specified tasks with optimum economy and efficiency.

Basic considerations to develop a design are 1.Design base matching the existing experience with R and D bringing in the latest material technology limitations in design convenience in production line and transportation working safety and reliability maintenance and repair environmental conditions P.Rameshbabu/saranathan/EEE Dept. Specificationmeeting with the customer’s requirements guarantees satisfy the national and international standards3. Design transfer Transfer of design to factory foreman i.e.
Drawings, processes instructions,job flow, meeting the delivery schedule.4. Information updatingTechnical journals, R and D papers and reports, interaction in meetings, seminars and conferences P.Rameshbabu/saranathan/EEE Dept. 5. Major considerations to develop a design are The design should be carried out based on the given specification using available materials economically and to achieve the following 1. Lower cost 2. Durability 3. Conformity with performance criteria as laid down in specifications P.Rameshbabu/saranathan/EEE Dept.
6. LIMITATIONS IN DESIGN 1. Saturation of magnetic partsIncreased core losses and excitation at higher flux density resulting in higher cost for the field system.
Temperature rise Increased temperature rise under higher output weakens the insulation and affects the life of machine. InsulationIt should be able to withstand the electrical, mechanical and thermal stresses which are produced in the machine. P.Rameshbabu/saranathan/EEE Dept. Mechanical strengthSpecially in turbo machine due to large size and high speed.
5.Efficiency If high efficiency is the aim, the machine becomes costly, for lower efficiency higher running cost and temperature rise with associated problems. Customer’s specificationsImposes limitations to identify criterion for best design 7. Commutation In DC machine output is limited because of commutation problem P.Rameshbabu/saranathan/EEE Dept.

Power factorPower factor imposes a limitation specially in case of 3 phase induction motor. 9.Standard specification Specification is biggest strain on the design because cy the both the manufacturer as well as the consumer cannot get away from them without satisfying them. P.Rameshbabu/saranathan/EEE Dept. 9. Basic structure of electrical machine1. Magnetic circuit: core,yoke, air gap etc.2.
Electric circuit: stator, rotor winding and transformer winding cy3. Dielectric circuit: insulation4. Thermal circuit: heating and cooling medium5.
Mechanical parts: frame, bearings and shaft P.Rameshbabu/saranathan/EEE Dept. 10. P.Rameshbabu/saranathan/EEE Dept. 11. P.Rameshbabu/saranathan/EEE Dept.
