<p>The present invention relates to a two-phase and two-row linear pulse motor enforcement system capable of protecting a field unit which is installed in the lower part of a moving body and offering the optimal installation structures of an armature unit and a search coil unit which are installed on the ground. The two-phase and two-row linear pulse motor enforcement system comprises the moving body (10) which comprises field units (11, 12), which are arranged on the lower part in a length direction in two rows, and a second field unit (30) which is arranged between the field units (11, 12); armature units (21, 22) which is arranged on a driving rail, generates a shifting magnetic field by using power supplied from a power conversion device, and generates the driving force of the moving body (10) generated by an interaction caused by a two-phase driving signal to correspond to the field units (11, 12); the search coil unit (40) which is installed between the armature units (21, 22) and detects electromotive force induced by a field magnet flux; and a control unit (50) which determines the position of the moving body (10) by receiving the signals detected in the search coil unit (40). The present invention further comprises a protective member (130) for protective prevention which is arranged on the lower part of the field units (11, 12) in transverse direction. The present invention is provided to prevent an accident which is generated by directly conflicting the uneven unit and the uneven part and the field unit of the ground rail.</p> |
