IHI’s electric jet: Developed the world’s first 1000kW class electric motor
・Achieved 1000kW using high-density molded coil technology
・Installed in the ‘tail cone’ of an aircraft engine
We will provide you with a summary of articles published in the Nikkan Kogyo Shimbun.
IHI:
・Electrification of aircraft and jet engines
On January 12th, IHI announced that it had developed a 1000kw class electric motor.
This electric motor is mounted on the ‘tail cone’ behind the engine.
A minimum of 1000kw is required to realize a hybrid electric propulsion system.
Global aircraft electrification race:
・Research and development of hybrids with engines
IHI has combined the newly developed electric motor and electric parts with an actual engine.
Aiming for the early realization of a hybrid electric propulsion system.
Conventional hybrid electric propulsion system:
In 2020, a 250kw class electric motor is used.
Developed a hybrid electric propulsion system in collaboration with Akita University.
New hybrid electric propulsion system:
Verifying the overall performance of the newly developed hybrid electric propulsion system.
We plan to release a new 1000kw electric motor in the mid-2020s.
Newly developed heat exhaust system:
1. Introduced a high-density molded coil system, and updated heat, fluid, and structure.
2. The exhaust heat system is operating normally with a 1000kw class electric motor.
Akita University Electrification System: Joint Research Center
We recently evaluated the performance of a new electric motor at a facility in Akita City.
It was confirmed that the expected performance could be fully achieved with the new electric motor.
Fields of application of hybrid systems:
1. The newly developed electric motor can supply electricity inside an aircraft.
2. It can respond to the increasing demand for electricity inside aircraft.

IHI Developing World’s First Aircraft Engine-Embedded Megawatt-Class Electric Motor
IHI Corporation News：
IHI and several domestic partners jointly developed the world’s first one-megawatt-class electric motor, mounted inside a jet engine tail cone .
More Electric Architecture for Aircraft and Propulsion (MEAAP) project：
１．aims to optimize the overall energy management of aircraft systems,
２．including engines, to help cut their carbon dioxide emissions.
IHI developed this motor:
under the Research and Development of Advanced Aircraft Systems for Practical Application Project of Japan’s New Energy and Industrial Technology Development Organization.
The global passenger jet fleet should double over the next 20 years on growing travel demand,
The MEAAP project seeks not just to electrify aircraft but also to significantly enhance fuel efficiency by optimizing aircraft systems, including engines,
to reuse cabin air, which current designs discharge outside aircraft without using effectively, to cool electrical equipment.
the Akita University Joint Research Center for Electric Architecture
IHI conducted assessments at the Evaluation Laboratory for Next Generation Motors of the Akita University .
This is the largest such facility in Japan.
Developing hybrid electric propulsion systems:
to electrify aircraft, and looks to demonstrate an engine-embedded electric motor during the middle of this decade.
One of the parts which are also under development,
IHI will electrify and optimize a range of propulsion systems, including hybrid electric propulsion systems for the future, and aircraft systems overall.
By combining a high-power electric motor for aircraft propulsion (note 6),
an electric turbo compressor ( note 7),
a high-flux plastic magnet rotor (note 8),
an electric hydrogen turboblower (note 9),
