SYSTEM HAVING COMBINATION OF PERMANENT MAGNET EXCITATION SYNCHRONIZATION TYPE MOTOR AND NON-CONTACT POWER SUPPLY DEVICE

摘要

PURPOSE: A system is provided to reduce weight of the system and save energy by adopting the permanent excitation synchronization type motor to the propel system. CONSTITUTION: A system comprises a permanent magnet excitation synchronization type motor for generating a linear driving force; and a non-contact power supply unit for receiving an electrical energy from the motor in a mechanical contact free manner. The permanent magnet excitation synchronization type motor includes a stator iron core(5) where a high frequency power is applied; a stator motor coil(5) for generating a shifting magnetic field to the stator iron core; a stator transformer coil(6) covering both sides of the stator iron core in a lengthwise direction; and a motor mover(2) moving in a lengthwise direction along the air gap of the stator iron core. The non-contact power supply unit includes an iron core(11), and a coil(12) wound at the iron core. The iron core and coil of the non-contact power unit shifts in a lengthwise direction along the air gap of the stator iron core.
