  1. 11. Oil-related Particle Emissions from Diesel Engines

    Författare :Petter Johansson; Sören Andersson; KTH; []
    Nyckelord :Diesel engine; Particle emissions; Particulate matter; PM; Lubrication oil; Inter-ring pressure; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : In recent decades much effort has gone into reducing particle emissions in the exhaust gases of heavy-duty diesel engines. Engine development has now reached the stage where it is worth to put heavy focus on the contribution of lubricating oil to particulate emissions in order to further reduce these emissions. LÄS MER

  4. 13. 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

  7. 15. Statistical approaches to PM steel process improvements

    Författare :Bjarne Bergquist; Alberto Molinari; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP; Kvalitetsteknik;

    Sammanfattning : Increased performance:cost ratios for PM steel components is vital if current growth rate of market shares of such components versus competing technology is to be sustained. Both performance and cost of components are affected by variation of component properties. LÄS MER
