Abstract:
An integrated system of a permanent magnet excited synchronous motor and a non-contact power feeding apparatus, comprising: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 consists of a stator core with an air-gap formed longitudinally at a side; 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 of the stator core, and wherein the non-contact power feeding apparatus consists of a core corresponding to a secondary core of a transformer; and wires winding the core, the wires corresponding to secondary windings of a transformer, the core and the wires of the non-contact power feeding apparatus sliding longitudinally along the air-gap.
