| Abstract | Characteristics of traction motors for electric vehicles (EV) should be high power density and high efficiency over the whole working area. The axial excited hybrid reluctant motor is fit for the EV application. In the motor, there are three excitation sources, which are permanent magnetic, armature, and axial coils. Controlling these excitation sources will make the motor run in different modes, which satisfy many kinds of conditions of the vehicle. With special structure and electromagnetic design, the electromagnetic torque includes reluctant torque, and the torque per unit volume is improved. Controlling the axial coil current will adjust the main flux. Then the flux weaken control is convenient achieved. When it is used as generator, main flux can be adjusted. The axial coil can also be used as position sensor. The electromotive force signal denoting the rotor position is added on the dc voltage applied on the axial coils. The paper introduces the structure and principle of the axial excited hybrid reluctant motor and resolves the electromagnetic torque. The axial magnetic field is analyzed. And the relation of the emf of the axial coils with the rotor position is produced. The simulation and experiment are made. The result shows that characteristics of this novel type motor satisfied the demands of the traction motor for EV. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
