New energy vehicles have bright prospect in the near future. In new energy vehicles some parts which are driven by engine through transmission will be replaced by electric drive, such as refrigeration compressor used for air conditioning and air compressor used for air brake system. Because of advantages, such as high efficiency, low friction, compact structure, and so on, linear compressor is suitable to solve above problems. In this paper a novel electric linear compressor is presented. Research work, such as simulation, structure design, control design, has been done. Further experiments are being done by my research team. We believe that electric linear compressor is worthy of being researched to popularize new energy vehicles.
