A high-speed motor for satellites -ETH Zurich (Department of Information Technology and Electrical Engineering)
22.07.2016 | News By: Peter Rüegg
A dizzying 150,000 revolutions per minute: researchers from ETH Zurich (Department of Information Technology and Electrical Engineering) and the ETH spin-off Celeroton have developed an ultra-fast magnetically levitated electric motor for reaction wheels. The high speed of rotation allows intensive miniaturisation of the drive system, making it attractive for use in small satellites. “Actually, there is nothing particularly new about it,” is the modest line taken by Arda Tüysüz, a postdoc at ETH Zurich’s Power Electronic Systems Laboratory (PES). “The electronics, the magnetic bearings, understanding of the basic physical principle – it was all there already.” However, the engineering skill of the PES researchers is evident in their ability to combine these fundamentals into high-speed motor, which can run 20 times faster than the state of the art, and which is vastly smaller and more energy-efficient. In collaboration with the ETH spin-off Celeroton, Tüysüz and colleagues have developed a new kind of magnetically levitated reaction wheel motor that reaches speeds of more than 150,000 revolutions per minute.
Electrically driven reaction wheels of this kind are used within satellites to change the satellite’s attitude. Here, the reaction wheel is connected to an electric motor via a shaft (rotor). As soon as the flywheel driven by this motor rotates in one direction about its own axis, a torque is transmitted to the satellite, which then rotates in the opposite direction and thus a new orientation.
Existing systems have numerous disadvantages In existing systems, the rotors and reaction wheels are typically mounted on ball bearings that wear down relatively quickly. In order to minimise mechanical wear, motors of this kind are usually operated slower than 6,000 revolutions per minute. They also have to be stored in a hermetically sealed housing in a low-pressure nitrogen atmosphere, in order to avoid oxidisation of the materials and evaporation of the lubricant.
Furthermore, the balls in a ball bearing are not exactly identical, giving rise to forces that together with the imbalance of the rotor transfer microvibrations to the satellite’s housing. This reduces the positioning accuracy, which satellites must exhibit in order to allow, for example, laser measurement or inter-satellite communication. In other words, enough reasons for ETH Zurich and Celeroton to design a new, magnetically levitated electric drive system.

“LAS CENTRALES HIDROELÉCTRICAS ME MOTIVARON A DESCUBRIR CÓMO LLEGA LA ENERGÍA A LAS CASAS” DR. JOEL DAVID MELO TRUJILLO ( UNESP-UNMSM)
Se suele decir que la inspiración llega en el momento o lugar menos esperado. Una central hidroeléctrica probablemente sería el último lugar imaginado por muchos, pero Joel, un niño muy curioso se sentía muy atraído por esta maravilla de la ingeniería. Cada vez que pasaba frentre a ella se preguntaba cómo era posible que allí se generara energía eléctrica y cómo ésta llegaba hasta las bombillas para iluminar su hogar. Esta inquietud lo llevó a desarrollar el proyecto titulado “La Casa del Futuro” en sus años escolares para competir en la Feria Escolar de Ciencia y Tecnología organizada por el CONCYTEC. Este proyecto terminó por reafirmar su pasión por la ingeniería a tal punto que a día de hoy es investigador del Departamento de Ingeniería Eléctrica de una reconocida universidad brasileña.
Conozcamos la historia del Dr. Joel David Melo Trujillo.
¿En qué colegio realizaste los estudios de primaria y secundaria? ¿Cómo fue la formación en ciencias que recibiste en tu colegio?
Los estudios de primaria y secundaria los realicé en los colegios particulares Lourdes y Santa Rita, respectivamente. Esos colegios se encuentra en el distrito de Lurigancho – Chosica, en la provincia de Lima, departamento de Lima. En la primaria, los profesores fomentaban los concursos en literatura y matemáticas, en el quinto grado de primaria llegué a ocupar el segundo puesto en el concurso de matemáticas. En el último año de la secundaria, dentro del programa curricular se preparó a los alumnos para el concurso de ciencia y tecnología organizado por CONCYTEC. Llegué hasta la etapa departamental con el proyecto titulado “La Casa del Futuro”. Tengo que reconocer que los profesores del área de ciencias exactas siempre motivaban a los alumnos a estudiar las materias, mas los recursos como laboratorios adecuados eran escasos, por ejemplo, no se tenía un adecuado laboratorio de química, teníamos que donar tubos de ensayo y traer algunos materiales de casa. También, no existía biblioteca, cuando estudié no todos tenían computadores en la casa y menos internet, así las informaciones para poder complementar lo aprendido en las aulas era poco.
¿Qué carrera estudiaste en pre-grado y en qué universidad? ¿por qué la elegiste o quién te motivó a elegirla?¿Cómo crees que nació tu vocación científica?
En el año 2002 entré a la Universidad Nacional Mayor de San Marcos (UNMSM) a la Escuela Profesional de Ingeniería Eléctrica. Mi vocación por la ingeniería eléctrica nació por causa del proyecto que mencioné en la respuesta anterior. Además, en Chosica están localizadas varias centrales hidroeléctricas, el pasar siempre por las centrales y ver las líneas de transmisión, éstas me llamaban la atención y me incentivaron a descubrir cómo es que llegaba la energía a las casas.
¿Qué estudios de post-grado haz realizado?
En el año 2009 llegué a Brasil para realizar estudios de post-grado en la UNESP campus de Ilha Solteira, donde obtuve los grados de magíster y doctor en los años 2010 y 2014, respectivamente. La investigación de post-grado fue realizada en el LaPSEE. Además colaboré con las investigaciones de otros alumnos y miembros de ese laboratorio.
Para realizar los estudios de postgrado ¿conseguiste alguna beca? ¿cómo la conseguiste?
En el año 2008, conocí al profesor peruano Ruben Romero de la UNESP, campus de Ilha Solteira, en una conferencia que se realizó en la Universidad Nacional de Ingeniería (UNI). El profesor mencionó que el sistema de post-grado es gratuito, además explicó los detalles del sistema de becas en Brasil. Existen varios tipos de becas, las cuales pueden ser agrupadas en institucionales y no institucionales. Las becas institucionales son auxilios económicos para que los alumnos se dediquen a tiempo integral a la investigación, imposibilitándolos, en la mayoría de las veces, a trabajar o recibir otro tipo de apoyo durante los estudios de post-grado. La atribución de esa beca depende de las programas de post-grado de cada universidad, en general, existe un sistema de selección. Las becas institucionales son ofrecidas en mayor número que las otras y fue la que obtuve. El sistema de selección que participé consistió en presentar mi hoja de vida y un proyecto de investigación.

DOCTORAL THESIS
On High-Frequency Distortion in Low-Voltage Power Systems -Anders Larsson- Luleå University of Technology Department of Engineering Sciences and Mathematics Division of Energy Engineering
Abstract
Power quality is a subject that has received a lot of attention during the last 10 to 20 years, both in industry and in academia. Power quality concerns interaction between the power grid and its customers and between the power grid and equipment connected to it, reflected in voltages and currents. Research and other developments in this area have to a great extent concentrated on relatively slow and low-frequency phenomena, with the main emphasis being on voltage dips (reductions in voltage magnitude with duration between about 50 ms and several seconds) and low-frequency harmonics (waveform distortion by frequency components up to about 2 kHz). These phenomena are reasonably well understood and several standards cover the area. For higher-frequency phenomena, above 2 kHz, there is no such general understanding, nor is there anything close to a complete set of standards covering this area. Modern energy efficient equipment connected to the grid, like fluorescent lamps but also solar panels, often uses switching technology, with switching frequencies that can range from a couple of kHz up to several hundreds of kHz. The grid is also used for communication of e.g. meter readings, system controls etc. This so-called power-line communication is using the same frequency range. The main frequency range of interest for this thesis has been the range from 2 to 150 kHz. There are two completely different measurement methods covering this frequency range: time-domain based and frequency-domain based. Time domain based measurements are used throughout the thesis. This gives an opportunity to choose between different analysing tools where among others the joint time-frequency domain has shown to be a useful tool for describing waveform distortion in our frequency range of interest. The majority of the measurements presented in this thesis have been directed towards fluorescent light powered by high frequency ballasts. This type of load has been, due to stringent harmonic limits, one of the first to use a more advanced switching technology called active power factor correction. This technique is also getting more frequently used in other small-power equipment, like computers. Installations of lights in stores etc. normally contain a large number of ballast connected together and the interaction is of importance, for example for setting emission and immunity standards. The measurements on ballasts presented in this work have shown that distortion in the frequency rage 2-150 kHz comes in three types: narrowband distortion; wideband distortion; and recurrent oscillations. The recurrent oscillations are a new type of powerquality disturbance that had not been recognized as such before. The measurements further have shown that the three types of distortion spread in a completely different way from the individual devices to the grid. This knowledge is essential for the setting of emission requirements on energy-efficient equipment.

Emission and Interaction from Domestic Installations in the Low Voltage Electricity Network, up to 150 kHz - Sarah Rönnberg -Luleå University of Technology Department of Engineering Sciences and Mathematics Division of Energy Science
Emission and Interaction from Domestic Installations in the Low Voltage Electricity Network, up to 150 kHz - Sarah Rönnberg -Luleå University of Technology Department of Engineering Sciences and Mathematics Division of Energy Science.
Abstract
This thesis work has focused on conducted emission (up to 150 kHz) from common lowvoltage appliances. The emphasis has been on equipment that contributes to a sustainable energy system: photovoltaic (PV) installations and energy-saving lamps (LED lamps). The frequency components present in the grid in addition to the fundamental 50 Hz component can be divided into harmonics (up to 2 kHz in a 50 Hz system) and supraharmonics (2 kHz to 150 kHz). These frequency components are partly the effect of normal operation of equipment due to power-electronic converters and the switching technique used. Power line communication, PLC, is an important source of frequency components in the range 9 to 95 kHz. Even though from an equipment viewpoint there is no difference between a signal used for communication and a signal that is a residue from a switching circuit, PLC is a useful signal for operation of the grid and for communication with electricity meters. The amplitude of the communication signal is in in almost all cases higher than the emission from any other equipment connected to the grid. Understanding the different types of interaction between PLC and end-user equipment has been a major part of this work. Five types of interaction have been identified; some negative for PLC, some negative for end-user equipment. An important conclusion from this part of the work is that loss of communication with PLC, as is often reported with remote reading of electricity meters, is not due to emission by end-user equipment but due to the EMC filter of the end-user equipment providing a low-impedance path. The understandings acquired from the work with PLC have been applied to other types of emission as well. Supraharmonics from individual devices, above about 10 kHz, flow mainly to neighboring devices, not into the grid. This behavior was found by laboratory experiments and confirmed by other studies as well. A circuit-theory model has been developed that explains this behavior. The EMC filters are shown to be the main cause of this behavior. Other configurations of those filters may result in a larger flow of emission towards the grid. One type of appliance that has been introduced recently is the LED lamp. LED.
