The LUT School of Energy Systems (Departments of Electrical Engineering and Mechanical Engineering) is looking for junior researchers in the following fields:
The Departments of Electrical Engineering and Mechanical Engineering are responsible especially for research and education in high-speed machine technology, advanced electrical drive systems and power electronics, active magnetic bearings and digital systems, as well as rotordynamics and the mechanical design of electrical machines.
The positions are funded by the Academy of Finland and LUT University. They are related to the Academy of Finland’s Centre of Excellence in High-Speed Electromechanical Energy Conversion Systems (HiECSs) and LUT University’s research platform Integrated Energy Conversion Machinery (INERCOM). This means that the junior researchers will work together, applying their wide-ranging expertise to develop high-performance electrical drives systems for industrial and mobile applications.
The duties of the positions may also include daily activities of the research team, such as supervision of trainees and undergraduate students and assistance in teaching.
Other qualities needed in the positions:
The main communication language is English. Therefore, the applicants are expected to have good verbal and written communication skills in English.
We have five positions available for applicants with the different study backgrounds and interests. Each position is described below in detail.
Positions 1 and 2: rotordynamics of high-speed electrical machines
In both positions, the researcher’s main task will be to conduct research for a doctoral dissertation in the field of rotordynamics of high-speed electrical machines.
Research in position 1 will concentrate on:
Research in position 2 will concentrate on:
Applicants are expected to have expertise in one or more of the following areas:
Position 3: power electronics
Research in this position will deal with high fundamental frequency power electronics (up to 3 kilohertz). The goal is to develop methodology to evaluate the performance of different converter solutions and thereby find the most suitable solution for different applications. To carry out the work successfully requires
Position 4: electrical motor design
The researcher’s main task will be to conduct research for a doctoral dissertation in the field of high-speed electrical machines, combining the study of high-frequency effects on machine performance, the optimization of the machine structure/materials/geometry to achieve the highest efficiency level, the thermal management of machines, and advanced electrical machine simulation methods.
We expect you to have a good understanding of electromechanics, electrical drive systems, and electrical motor topologies. This position will require advanced knowledge of the design of high-speed electrical machines.
Applicants need to understand finite element method simulation tools and have experience in using them for electric/magnetic/thermal analysis. Further, applicants should have a basic understanding of rotor dynamics, power electronics, and control principles to communicate with other experts on the project.
We offer encouraging and supportive supervision and research collaboration by Professor Juha Pyrhönen and Dr Ilya Petrov.
Position 5: control
Research in this position deals with active magnetic bearing control for high-speed machines.
The Laboratory of Control Engineering and Digital Systems is looking for a doctoral student. The laboratory operates under the Department of Electrical Engineering, which has a long history and strong background in the development of electrical drives and their control for special industrial applications. A motivating example of such applications is a high-speed drive designed for demanding industrial applications where a high-speed machine with an active magnetic bearing supported rotor system is applied instead of traditional solutions. In these applications, embedded intelligence has an important role in providing a stabilizing control solution, but it also offers possibilities for more advanced routines.
The research will focus on the development of intelligent control, diagnostics, automatic commissioning and modern data analytics routines for modern high-speed electrical drive applications. Applicants are expected to have a background in both control and electrical engineering. However, motivated candidates with a strong background in electromechanics or mathematical modelling may also be considered for the position. The selected applicant may also participate in research on the advanced data-based modelling and control of various high speed drive applications.
The selected applicant would mainly focus on research on active magnetic bearing technology based machines – specifically on the development of advanced MIMO control routines to stabilize the rotor system under time-varying operating conditions.
Applicants must have a Master’s degree or the equivalent in a relevant field (e.g. energy, thermal, mechanical or process engineering) and the ability and motivation to complete the doctoral studies within the normative duration of the studies for the degree (i.e. four years). An employment contract can only be concluded if the applicant obtains the right to pursue doctoral studies at LUT University.
The employment will start as soon as possible with a one-year term including a six-month trial period, and it can be extended for another three years provided that the studies have progressed satisfactorily.
The salary is based on the current collective agreement for Finnish universities. The typical gross annual starting salary for a junior researcher is around 30 420 euros (plus a holiday bonus).
