Permanent magnets rotor for high-powered synchronic motors for hybrid and plug-in vehicles performance

The Spanish research group is an interdisciplinary and interuniversity group in the areas of knowledge of mechanical and electrical engineering. This Spanish research belongs to a medium-sized Spanish university founded in 1994, housing others 76 research groups more. The university has been very active in several European research and innovation programmes (H2020 and previous frame programmes, LIFE, Justice, ERASMUS+, Interreg, COST, LLP, IEE, Research Fund for Coal and Steel, D. G. for Competition Policy and Strategy, Science for Peace and Security Programme-OTAN…) with over 50 European projects; with the role of coordinator in 22 projects and over 8.4 M€ overall EU funding received. Currently, this university participates in 26 on-going projects (in 12 of them as coordinator) in 8 different EU programmes with an average of 1.7 M€ of EU funding in the last 4 years. The circular arch shape of the permanent magnets offered layout of the new rotor offered, improves the reluctant component of the torque, forming a double layer magnetic field. Moreover, the use of rare earth elements powder agglomerated magnets (elements like cerium, yttrium or neodymium) results energy values similar to those obtained with known sintered magnets. In permanent magnets rotor, for use in synchronic three-phase motors for hybrid and plug-in vehicles, there are two magnetic layers in the rotors that generates the motor action, disposed as an arch of a circular segment geometrically optimized, improving the reluctant and magnetic components of the torque. To set both magnetic layers, rare earth elements powder agglomerated magnets are used, instead of sintered ones, allowing different geometry that improves the reluctant torque. The magnets used are made with agglomerate materials, conforming magnets with less materials and similar energy values than does used currently. The combination of the double magnetic layer and the characteristics of the new magnets, the new rotor obtains a 20% more torque than known rotors. The weight of the motor, its cost, and the economical loses are also reduced. The potential application for this curved poles rotor with agglomerated permanent magnets for synchronic three-phase motors is the use on electric motors for hybrid and plug-in vehicles performance improvement. The researcher group is interested in international cooperation under license agreement and/or manufacturing agreement, with other research organization or universities and any size companies.
