Electric compressor ES14
We have developed car air-conditioning compressors with a built-in electric motor for use in electric vehicles and hybrid cars. These compressors are smaller and lighter in weight than compressors powered by gasoline engines, and their highly efficient operation are able to improve fuel sfficiency of the vehicle in which they are installed. Since the motors are built into the compressor, there is no need a shaft seal and it leads better airtight design.
We successfully integrated into the compressor an inverter that previously required to be installed on the cooling system, and we realized a more compact and lightweight compressor that can contribute to vehicle compactness.
