SAS2H: A Coupled One-Dimensional Depletion and Shielding Analysis Module

A linear comb-shaped synchronous motor includes a tubular-shaped reaction rail, an excitation conductor extending through said tubular shaped reaction rail, and a moving member containing an armature. The tubular shaped reaction rail has at least one zigzag slit along the longitudinal direction thereof and each side of the reaction rail is provided with comb-shaped pole members. As current flows through the excitation conductor, the comb-shaped pole members are magnetized such that the comb-shaped pole members aligned along one side of the zigzag slit make a trail of south poles and the comb-shaped pole members aligned along the other side of the zigzag slit make a train of north poles. The moving member is placed near the reaction rail through an air gap between the armature and the pole members, and the same is driven along the reaction rail.
