Design, Development and Testing of Moving Magnet Linear Motor Compressor

Rahul Awargand | Maruti Khot ^[2] | Vikram More

Abstract: Cryocoolers are special equipment developing lower temperatures. The main part of cryocooler is compressor. Compressor consumes most of the energy of system, so by developing the efficient compressor energy can be saved. The old compressors uses crank mechanism to convert rotary motion to linear motion but it causes friction and loss in the efficiency. Moving magnet or moving coil linear motor actuators can be used in linear motor compressor. Moving magnet compressor uses permanent magnets and coil. In moving magnet compressor magnet moves and coil stays stationary. The coil excites equal and opposite forces on magnets with 10mm axial displacement and at low capacity. The present work aims to design, develop and manufacture a linear moving magnet compressor using flexural bearing.
