As known, linear actuators used for automation and industrial processes should present high performances, in terms of force amplitude, enhanced dynamic response, low cogging and reduced force ripple, small e.m.f. waveform distortion, structural simplicity, compactness and robustness, low cost. Achieving all these goals is not a simple task: the paper describes some configurations, design criteria and performances of a few permanent magnet (PM) actuators, whose armature structures, iron-core and toothed, are equipped with symmetrical three-phase windings made of concentrated coils, suited to fairly satisfy the described requirements. Key words− concentrated windings, iron-core PM actuators, low cogging and torque ripple, sinusoidal E.M.F.s.

Abstract
As known, linear actuators used for automation and industrial processes should present high performances, in terms of force amplitude, enhanced dynamic response, low cogging and reduced force ripple, small e.m.f. waveform distortion, structural simplicity, compactness and robustness, low cost. Achieving all these goals is not a simple task: the paper describes some configurations, design criteria and performances of a few permanent magnet (PM) actuators, whose armature structures, iron-core and toothed, are equipped with symmetrical three-phase windings made of concentrated coils, suited to fairly satisfy the described requirements. Key words− concentrated windings, iron-core PM actuators, low cogging and torque ripple, sinusoidal E.M.F.s.| File | Dimensione | Formato | |
