The origins of this technology date back almost 30 years. In fact, the static interaction between the field produced by an electromagnet and the one from a magnet was discovered in 1970 by the inventor's uncle Carlos Subieta Garrón, who passed away in 1974. Since then, the inventor was able to use this phenomenon and include it in a dynamic system applying it to a Hybrid Electric Reluctance motor. In this system, the permanent magnets work the same way as the electromagnets, switching it´s field ON and OFF thousands of times per minute becoming, hence, an additional source of energy that increases the power output of the motor, resulting in higher efficiency and lower weight.
During the period the inventor was living in the USA, working as an executive in engineering companies. He got the sponsorship of Mr. George S. Moore, Former Chairman of Citicorp of New York (Citibank). With this support, the inventor conducted several experiments and research with different scientific partners. One of these partners was the University of Tennessee, Knoxville, in the Unites States of America, which cooperated with the inventor under the guidance of Dr. Igor Alexeff (Nuclear Engineer) and Milton Bailey (a top american scientist in the fields of electric motors and other related scientific areas). These scientists were both eminent (emeritus) professors of the State University of Tennessee, Knoxville.
After moving to Bolivia, the creator of this technology faced several constraints and difficulties related to the lack of access to more scientific support and financial resources. One of the most important problems was to the lack of adequate R&D facilities, team, and laboratories, which practically do not exist Bolivia for these kind of scientific fields. All these constraints delayed the progress of the R&D process and the commercialization of this invention that would favour the society in general.
In 2009 he started a partnership with Fundació Equilibri, a foundation settled in Barcelona which was commissioned to assume the project coordination and to establish new linkages and cooperation for further research. The first experimental motor was built in Bolivia by the inventor, with the help of Eng. Javier Adelantado, an experienced engineer from Barcelona, Spain. This motor and its functioning principle have been studied for four years by the GAECE (Electronically Commutated Motor Drivers Group), a specialized group of scientists of the Polytechnic University of Cataluña (Spain). The study, which includes mathematical evaluations and computer simulations performed by advanced programs (Finite Elements, Flux 2D Simulink Mathlab), was complemented with the construction of a small motor named Alfa IE4 MHR 3P NR5 including the inventor's technology. The small prototype produced 47% more power output in relation to reluctance motors or induction motors and D.C. motors of the same size in the market. The small machine also rached the highest norm IE4 for efficiency
Publications and presentations
The prototype Alfa IE4 MHR 3P NR5, which is based on our technology, was presented at the XXth International Conference on Electrical Machines on September the 2nd, 2012, in Marseille, France.
The GAECE Group published in IEEE* Transaction on Industrial Electronics under the title of A Novel type of Hybrid Reluctance Motor Drive. Of course, this publication is also based on the the inventor’s technology (August 1st, 2014).
GAECE group also presented the motor and other apparatus based on our technology at the International Conference on Renewable Energies and Power Quality in La Coruña, Spain, on March 25th, 2015.
