The project has been dedicated to the following activities in each WP.
WP1: Project management
The technical progress, financial aspects and potential issues concerning the development of the project has been monitored through regular (virtual and physical) meetings held between the research groups of Alconza, Antec, Suprasys and Ceit.
WP2: Challenges and technology potentials for electrical propulsion drives
A detailed analysis of the non-superconducting (NSC) technology for electric aircraft propulsion and its limits was performed in this WP, including a complete modelling of different electric motor topologies and cooling systems through FEA and CFD simulations.
WP3: Fundamental understanding and modelling of high-power systems at high altitude
In this task, firstly, a brief state of the art is developed introducing partial discharges and the existing work in bibliography on their detection, with a focus on aeronautical propulsion. On this chapter, a classification of the partial discharges is presented, as a function of the topology of the discharge and the medium surrounding the test unit. Moreover, different aspects of this phenomena are assessed as follows: detection methods of partial discharges, usually used measuring equipment, PRPD and PSA pattern recognition, acceptance limits and the time-frequency map. This chapter concludes with a brief explanation of the standards on which the test will be based.
Later, the information relative to the tests performed regarding the insulation assessment of different elements of the designed electric motor and their reliability and safety is retrieved. First, tests assessing the dielectric strength of winding slot insulation material are performed under different surrounding conditions, and the obtained values are compared with the ones provided by the material supplier. The different conditions are obtained varying the temperature, relative humidity, and pressure parameters and a test with the specimen immersed in oil shall be performed.
WP4: Design of a MW-class HV HTS motor
The main outcome of this WP is the design of a 2 MW HTS HV electric motor and the design of a mock-up to validate the key points of the design, consisting on a scale electric motor.
WP5: Experimental Development
Based on the results of the conceptual design carried out in the WP4 Design of a MW-class HV HTS motor, the manufacturing design of the scale demonstrator was carried out.
WP6: Test evaluation
The main goal of this WP is to validate the design and manufacture of the mock up. Therefore, a series of functional tests have been carried out on the different active parts of the motor as well as on the motor assembly.
WP7: Dissemination and exploitation
A number of communication and dissemination activities have been carried out within the project, resulting in a dedicated website (
https://hivomot.eu/(s’ouvre dans une nouvelle fenêtre)) and Twitter (
https://twitter.com/hivomotproject(s’ouvre dans une nouvelle fenêtre)) whereby disseminating the project results.
With regards exploitation, 4 different HIVOMOT products have been identified, classified under Key Exploitable Results (KERs). For these KER, an exploitation and business plan has been developed.
Also, 2 articles in journals have been published and a patent has been developed. In addition, there has been representation of HIVOMOT’s members in different conferences and workshops during the project.
