| Abstract | This paper describes a super-multipolar permanent magnet reluctance generator (PMRG) for small-scale renewable energy generation. The numbers of stator and rotor poles of the PMRG are 72 and 96 respectively, in order to be directly connected to the turbine without a gear box. The rated power of the designed PMRG is about 1.0 kW at 100 rpm. The PMRG has two features for reducing torque ripple; the first one is a two-stacked structure, namely, one rotor is shifted by 180 deg. in electrical angle from the other rotor; the second one is that the rotor pole-tips are cut off so that the torque waveform consists of only odd-harmonics. In such a structure, the torque ripple of the PMRG can be reduced drastically. In this paper, first, the shape of rotor pole-tips is optimized by two-dimensional finite element method (2D-FEM) coupled with a general purpose optimization program. Next, the load characteristics of the PMRG obtained from 3D-FEM are indicated. Finally, the measured characteristics of the developed 72/96-pole PMRG are described. |

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.
