World’s highest level output: IHI’s electric turbo compressor!
-Achieves 100 kW output, 3.5 times greater than conventional products-
Report from IHI’s technical disclosure information
IHI’s electric turbo compressor:
IHI has developed an electric turbo compressor with the world’s highest level of output.
Equipped with a unique air-floating gas-bearing electric motor.
Achieved an output of 100 kW, which is 3.5 times that of conventional models.
Electric turbo compressor developed by IHI:
Used in hydrogen fuel cell propulsion systems.
It is expected to be used in hydrogen fuel cell propulsion systems for small aircraft.
A large amount of compressed air can be supplied even in thin air. Realize an airplane with a fuel cell propulsion system.
Role of electric turbo compressor:
The electric turbo compressor reacts hydrogen with the fuel cell and supplies compressed air.
It supplies a large amount of compressed air to obtain high output.
The steam discharged from the fuel cell is used for power.
Applications other than fuel cell systems:
It compresses the thin outside air during flight and supplies it to the cabin air conditioner.
It is also expected to play a role in recovering energy from the compressed air in the cabin.
Developed “hydrogen conversion by electric propulsion system and on-board power generation system”.
Aiming for commercialization in the 2030s.

IHI Develops One of World’s Lightest and Most Compact Electric Turbo Compressors Incorporating Proprietary Air Bearing Technology that Could Help Materialize Aircraft Fuel Cell Propulsion Systems
2023FY｜News｜IHI Corporation
IHI’s envisioned applications for this new compressor include fuel cell propulsion systems
for small passenger aircraft, energy-efficient air conditioning in 200-seat medium-range airliners,
and in aircraft fuel cell systems, which could replace gas turbine generators to decarbonize aviation.
As part of NEDO work,
IHI endeavored to attain ultra-high speeds with a turbo compressor motor and meticulously lighten rotating parts.
It also used a newly developed large-capacity air-floating gas bearing.
It thereby succeeded in creating an air-floating permanent magnet rotor and high-powered impeller.
A Halbach array is a special arrangement of permanent
magnets
To achieve a compact, light, and powerful motor, IHI used a high-density magnetic array (see note 2) to maximize magnet utilization efficiency.
The array makes it possible to arrange a large number of small north-south pole magnets in a permanent magnet motor.
