| Summary: | The paper describes the analysis of a short stroke, tubular moving-magnet actuator which employs multi-segmented, trapezoidally shaped, radially and axially magnetised magnets. The open-circuit magnetic filed distribution is established analytically in terms of a magnetic vector potential formulated in the cylindrical coordinate system. The analytical field solution allows the prediction of flux linkage, back-emf and thrust force of the actuator in closed forms and facilitates design optimisation. The analytically predicted results are validated by finite elements analyses. |
