Abstract

The present invention relates to an integrated system in which a bilateral permanent magnet excited synchronous motor part and a non-contact power feeding part are combined in order to generate a linear driving force and to feed an electric power without any contact. The present integrated system comprises a bilateral permanent magnet excited synchronous motor for generating a linear driving force; and a non-contact power feeding apparatus for receiving an electric power without any mechanical contact from the bilateral permanent magnet excited synchronous motor, wherein the bilateral permanent magnet excited synchronous motor is composed of a stator core with a long air-gap formed at one side, a stator motor windings inducing traveling magnetic fields in the stator core, stator transformer wires winding both flanks of the stator core, and a motor runner sliding longitudinally along the air-gap, and wherein the non-contact power feeding apparatus is composed of a secondary core, and secondary wires winding the secondary core. The present invention enables non-contact power supply by simply installing a long core at the part of a runner and winding wires around the long core and a stator transformer, therefore, this non-contact power feeding way reduces the cost of system manufacture and provides very clean transportation system.
