Autor: Niko Nevaranta, Jukka Parkkinen, Tuomo Lindh, Markku Niemelä, Olli Pyrhönen, Juha Pyrhönen

Publikováno v: Modeling, Identification and Control, Vol 36, Iss 3, Pp 157-165 (2015)

A proper system identification method is of great importance in the process of acquiring an analytical model that adequately represents the characteristics of the monitored system. While the use of different time-domain online identification techniqu

Publikováno v: Immonen, P, Ponomarev, P, Åman, R, Ahola, V, Uusi-Heikkilä, J, Laurila, L, Handroos, H, Niemelä, M, Pyrhönen, J & Huhtala, K 2016, ' Energy saving in working hydraulics of long booms in heavy working vehicles ', Automation in Construction, vol. 65, pp. 125-132 . https://doi.org/10.1016/j.autcon.2015.12.015

Hybridization of heavy off-highway working vehicles brings considerable energy savings in the form of a downsized internal combustion engine (ICE) by means of reduced no-load losses. In this paper, a novel energy saving opportunity in working hydraul

Uncertainty of the Entropy Change Calculation By Cylindrical Li-Ion Cell Heat Flux Measurements: Temperature and C-Rate Effect

Autor: Kirill Murashko, Andrey Mityakov, Vladimir Mityakov, Sergey Sapozhnikov, Juha Pyrhönen, Jorma Jokiniemi

Publikováno v: ECS Meeting Abstracts. :138-138

The entropy change (ΔS) of a Li-ion battery during its charging and discharging is one of the important parameters, which has a strong effect on the heat generation in a Li-ion battery during its operation. Moreover, the behavior of the entropy chan

A novel rotor structure for an Axial Flux PM machine: Performance analysis

Autor: Juan A. Tapia, Werner Jara, Juha Pyrhönen, Pia Lindh

Publikováno v: 2016 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM).

This paper presents the performance analysis of a new two stators and central rotor Axial Flux Permanent magnet machine with tooth coil winding. The novel rotor topology proposed has a non-ferromagnetic structure that reduces the leakage flux and als
