1. 1. Design and Evaluation of a Compact 15 kW PM Integral Motor

   Författare :Peter Thelin; KTH; []
   Nyckelord :integral motor; integrated motor drive; PM motor; PMSM; compact motor; filter coil; airgap flux density; axial leakage;

   Sammanfattning : This thesis deals with the integral motor of tomorrow, and particularly with a variable speed, sensorless permanent magnet synchronous motor with an integrated converter. The rated power is 15 kW at 1500 r/min. The outer dimensions are approximately the same as for the equivalent standard induction motor.Control strategies for pumps and fans, i. LÄS MER

3. 2. On design methods for mechatronics : servo motor and gearhead

   Författare :Fredrik Roos; Jan Wikander; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; mechatronics design methodology; servo systems; electric motors; gears; auxiliary systems; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

   Sammanfattning : The number of electric powered sub-systems in road-vehicles is increasing fast. This development is primarily driven by the new and improved functionality that can be implemented with electro-mechanical sub-systems, but it is also necessary for the transition to electric and hybrid-electric drive trains.

4. 3. Vehicle Conceptualisation, Compactness, and Subsystem Interaction : A network approach to design and analyse the complex interdependencies in vehicles

   Författare :Sai Kausik Abburu; Carlos Casanueva; Ciarán J. O'Reilly; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Subsystem interaction; Interaction effects; Design Structure Matrix; Network theory; Cross-scalar design tool; Induction motor; Inverter.; Farkostteknik; Vehicle and Maritime Engineering;

   Sammanfattning : The conventional approach to vehicle design is restrictive, limited, andbiased. This often leads to sub-optimal utilisation of vehicle capabilities and allocated resources and ultimately entails the repercussions of designing andlater on an using an inefficient vehicle. LÄS MER

   Sammanfattning : This thesis presents studies of molecular motors in interaction with nm-scale structures, as well as the development of a set of tools that can be used for the construction of custom-designed nano-transportation systems. In our studies, we have used the latest nanoscale technology and combined this with advanced results from chemistry and biomedical sciences. LÄS MER

7. 5. On Fluid Power Pump and Motor Design : Tools for Noise Reduction

   Författare :Liselott Ericson; Jan-Ove Palmberg; Kalevi Huhtala; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Noise and vibration are two of the main drawbacks with fluid power  systems. The increasing requirements concerning working environment as well as machines' impact on surroundings put components and systems to harder tests. The surrounding machines, e.g. LÄS MER
