The invention is applicable to the travel control field, and provides a travel control apparatus and a linear motor employing the travel control apparatus. The travel control apparatus comprises a main case, a supporting shaft mounted in the main case, magnetic conductive arms mounted on the supporting shaft, control coils winding the magnetic conductive arms, multiple magnetic conductive rings that are matched and interact with the magnetic conductive arms, and multiple isolating rings for isolating adjacent two magnetic conductive rings, wherein the magnetic conductive rings and the isolating rings are arranged alternatively in a laminated manner; and each magnetic conductive ring and each isolating ring are fixed in the main case. The magnetic conductive rings and the isolating rings are arranged alternatively in a laminated manner; the control coils wind the magnetic conductive arms, so that the positions of the magnetic conductive arms can be controlled by regulating the magnetic force of the coils and the interactions of the magnetic conductive ring, and accurate control can be achieved; due to the structure, the magnetic conductive arms and the control coils can be smaller in dimensions in manufacturing; in addition, the magnetic conductive rings and the isolating rings can be smaller in dimensions in manufacturing as well, so that the volume miniaturization of the travel control apparatus is realized; and furthermore, an external power motor or a motor is not required, so that the travel control apparatus is more power-saving.
