Abstract

PURPOSE:To reduce the horizontal component force support of a linear motor by protruding a plate-shaped secondary side conductor from a climbing body, providing a supporter having a U-shaped cross section and surrounding the secondary side conductor in the U-shape on a hoistway, and fitting primary side coils on both side walls in the U-shape respectively. CONSTITUTION:A primary side coil is connected so that the relative positions of a secondary side conductor 9 and primary side coils 8 are set to the preset conditions and horizontal component forces in the width direction and the depth direction of a hoistway 1 are offset when a linear motor is excited. When a climbing body 3 is lifted or lowered by the linear motor, the climbing body 3 is theoretically held at the preset position in the horizontal direction of the hoistway 1. The horizontal load applied to the climbing body 3, a guiding tool 3a and a guide rail 7 is reduced when the climbing body 3 is lifted or lowered. The horizontal component force are applied on both faces of the secondary side conductor 9 and offset. Relevant members such as the climbing body 3 are not required to be strongly manufactured in particular, and an elevator can be made lightweight and manufactured at a low cost.
