| Abstract | In this study different noise and vibration measurements on a multi-phase 12/8 switched reluctance (SR) motor for automotive applications are carried out on a test rig and analysed with vibro-acoustic techniques. When evaluating the behaviour of rotating machinery for HEV applications, it is necessary to perform a vibro-acoustic analysis. The reason for this is that these specific noise and vibration contribute significantly to the perceived overall sound quality in the passenger compartment and outside the vehicle. Vibrations or high frequency tonal acoustic noise could be annoying for the passengers or could even cause long term damage. Therefore, the noise and vibration must be deliberately optimized. In case of a SR motor, the radial magnetic force between stator and rotor is a main excitation source to create large deformations of the stator housing, causing serious vibrations and acoustic noise. Measurements and results of simulations in different load conditions are compared. In addition, the dominant vibration modes are verified by modal analysis and operational deflection shapes. The unpleasant tonal acoustic radiation of this electric motor is objectively quantified by noise metrics. Finally, the relationship between the current profiles, radial magnetic forces, and mechanical and acoustic vibrations is investigated to obtain a better insight into the root cause of the vibro-acoustic behaviour of the motor. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
