    H-uppsats, Chalmers tekniska högskola/Institutionen för energi och miljö

    Författare :Anton Klintberg; Jimmy Björkman; [2014]
    Nyckelord :Tubular Linear PMSM; percussive drilling; sensorless current control; signal injection; SCVM.;

    Sammanfattning : This thesis presents a control strategy for a percussive drill driven by an oscillatingTubular Linear Permanent Magnet Synchronous Machine (TLPMSM). The drillconsists of a piston with permanent magnets and a casing with integrated statorwindings. The casing encapsulate the whole unit and should be used to hammerinto rocks. LÄS MER
