Abstract
The slot-less tubular permanent magnet linear motor was selected as a linear actuator using for the attitude control of aircraft. The winding distribution factor of the annular slot-less winding was researched. The model of the winding factor distributing along the axis that considered the influence of the phase-to-phase insulation was established. The winding distribution characteristics of the single-polar and bipolar windings were compared. The influence of the phase-to-phase insulation on the winding distributions for these two windings was expounded. A slot-less tubular linear actuator prototype was manufactured. The tested and calculated no-load electromotive force (EMF) waves were consistent, which verified the validity of the theoretical study. And the thrust and dynamic response characteristics were tested. The results reflect that the linear actuator is with the advantages of small armature reaction and quick dynamic response speed.
