  1. 11. Development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the contextof hydrogen mobility

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : WULLSCHLEGER LÉA; [2023]
    Keywords : Liquefaction cycle; multi-streams heat exchanger; Matlab; PROOSIS; AMESIM; ArianeGroup;

    Abstract : This paper presents the master thesis work done at ArianeGroup on the development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the context of hydrogen mobility. In 2015, the Paris Agreements aimed at strengthening the global response to the threat of climate change by keeping the temperature rise below 1. READ MORE

  3. 12. Sensorless Hybrid Field-Oriented Control Two-Phase Stepper Motor Driver

    University essay from Linköpings universitet/Reglerteknik

    Author : Emil Lydell; [2023]
    Keywords : Stepper motor; Field-Oriented Control; FOC; Driver; Two-Phase; 2-Phase;

    Abstract : Hybrid stepper motors are small electrical motors with high torque production, compared with other electrical motors of the same size. Hybrid stepper motors are reliable in open-loop systems, in Sinusoidal mode, but with a drawback of high power consumption. READ MORE
