Abstract :
An ideal coreless linear motor produces no forces in non-driving directions. However, in practice, the translator can be misaligned with the center of the stator due to manufacturing tolerances, which causes undesired normal parasitic forces. This misalignment on the other hand provides the ability to generate force in the normal direction. This paper proposes a novel commutation method which utilizes this ability to compensate for normal parasitic forces caused by the misalignment of the translator as well as other manufacturing tolerances. The proposed commutation algorithm is fully analytical and hence requires low computational power. Simulation results are presented to demonstrate the effectiveness of the proposed commutation algorithm.
