In addition to emergency power generation equipment, we also provide cogeneration power generation systems for the purpose of energy conservation and CO2 reduction in factories and facilities. Engineers in the fields of electricity, mechanics, control, and project management are active in the development and management of these facilities, and we are continuing to recruit personnel.
Motors are an indispensable source of power for all kinds of industries, including railways, large pumps and fans, and factory equipment. Since developing Japan’s first domestically produced 5-horsepower induction motor in 1910, Hitachi has pioneered the history of motors in Japan through numerous advanced technologies that have led the times. As motors play a critical role in industry, they require highly efficient and reliable designs, and development covers a wide range of items such as temperature, vibration, noise, and the adoption of new materials. By leveraging the latest simulation technologies and bringing together strong teamwork, we deliver high value-added products to the global market.
With advances and progress in power electronics and control technologies, the performance of AC variable-speed motors has improved dramatically, and their application in steel plants has become well established. By adopting variable-speed AC drives-enabling faster response, higher efficiency, and an expanded field control range-many plants have achieved significant improvements in productivity and quality, along with reduced maintenance requirements and lower energy consumption. Building on our extensive experience and proven track record in rolling mill drives, we manufacture and supply high-performance, high-quality, and highly reliable AC variable-speed motors backed by advanced analysis technologies, state-of-the-art production facilities, and rigorous quality control.
Ultra-large dump trucks in the 300-500 ton class (gross vehicle weight) used to transport ore excavated at mining sites are electrically driven to achieve superior controllability and higher efficiency. Electric power generated by the on-board engine is used to drive the dump truck via inverter-controlled motors. We develop and commercialize the generators and motors used in these electric drive systems.
Power electronics is a technology used to convert electricity-such as from AC to DC or from DC to AC-according to specific applications and equipment requirements. By combining our high-quality motors with inverters that provide appropriate operational control based on the load, we contribute to a wide range of industrial fields, including energy savings in factories and plants, as well as CO2 reduction in social infrastructure such as power plants and railways.
In addition, we support the creation of a sustainable society by supplying products that incorporate cutting-edge technologies across a broad range of fields-particularly those that handle high voltage and high power or require advanced control technologies-such as inverters for renewable energy (wind and solar power generation), motor drive inverters for electrically driven ultra-large dump trucks used in mining, and uninterruptible power supply systems (UPS: Uninterruptible Power System) that provide stable electric power.
As the shift to EVs accelerates toward achieving carbon neutrality, expanding charging infrastructure has become an urgent priority. In particular, as demand grows for rapid charging of large commercial EVs, our high-capacity, ultra-rapid charging multi-port EV charger is designed to meet these needs. Compliant with the next-generation CHAdeMO 3.1 (ChaoJi 2) standard, it can connect up to 20 ports to a single power source. It also supports V2X* and contributes to stabilizing the power grid.
*V2X (Vehicle to Everything): A function that supplies power from an EV to various destinations, such as the grid and buildings.
We provide high-voltage direct inverters that directly drive high-voltage motors used for large pumps and fans. By applying new materials and manufacturing methods, and leveraging a wide range of simulation technologies―such as electromagnetic field analysis and thermal-fluid analysis―we achieve a rational structural and system configuration that meets the needs for smaller and lighter equipment. These inverters contribute to improved controllability and energy savings in industrial facilities.
As electrification of large dump trucks accelerates to improve energy efficiency and reduce labor, we provide electric drive systems that use high-voltage, high-capacity inverters to deliver high-performance electric drive trucks.

In addition, as digital transformation (DX) and IoT adoption accelerate across society and industry, industrial computers are expected to deliver more than just control functions. They must also be capable of collecting real-time data from sensors and other sources, performing immediate analysis, and executing edge processing.
To meet these needs, we develop industrial computers and industrial controllers that enable seamless collaboration across Product × OT × IT. By collecting and utilizing operational data from production equipment as big data, for example, we help improve manufacturing efficiency and support smarter operations across a wide range of fields.
In the Mechanical Systems/Mechatronics Division, we conduct research, design, development, and manufacturing of essential products that support society and industry. These include industrial machinery such as compressors, pumps, and blowers that mainly control water, air, and gas, as well as logistics systems that support a wide range of plant operations. We also develop next-generation safety and security solutions, including earthquake simulators and vehicle running test systems.
Our field of activity is expanding not only across Japan but also globally. Leveraging the R&D expertise we have built up over many years and cutting-edge technologies, we are tackling global challenges such as ensuring a stable energy supply, alleviating water shortages, and strengthening disaster preparedness―helping shape the society of the future.
A compressor is a machine that pressurizes and delivers gas by means of mechanisms such as the rotational motion of an impeller/rotor or the reciprocating motion of a piston. High-performance compressors are essential for the compression, transportation, and circulation of the gases we use in everyday life.In recent years, demand for turbo compressors has also been increasing due to concerns such as the depletion of underground resources, including oil, and the growing need for environmental considerations. Turbo compressors play a vital role as the “heart” of plants such as oil refineries and natural gas facilities, and are used across the world.
We have delivered a cumulative total of more than 1,000 units, mainly overseas. More recently, we have also been developing compressors installed on offshore vessels for extracting subsea oil fields off the coast of Brazil.Similar machines include fans and blowers. These are essentially the same type of machine, and the terminology varies depending on the application.
We design, develop, and manufacture pumps―primarily large-scale models―ranging from those used in Japan’s public sector, such as water and wastewater treatment plants and drainage pump stations, to pumps for power generation facilities including nuclear and thermal power plants.As demand for pumps continues to grow as a key solution to water shortages around the world, we also participate in major global projects and have delivered numerous pumps worldwide. In California, USA, we developed, designed, manufactured, and delivered an 80,000-horsepower turbine pump―at the time the world’s most efficient―for the Edmonston Pumping Plant, the most critical facility in the approximately 960 km water conveyance system that runs through the state from north to south.
Thanks to our advanced technology, these pumps achieve both high efficiency and high performance, earning strong recognition from California state authorities and contributing to securing water resources in Southern California.
A blower is a large-scale air-moving machine used for applications such as tunnel ventilation and plant facilities. We handle a wide range of models, including large axial-flow ventilation blowers and jet blowers for systems that exhaust fumes accumulated in tunnels; large axial-flow and centrifugal blowers for thermal power plants and steel mills; turbo blowers for wastewater treatment plants; centrifugal blowers for Shinkansen cabin ventilation; centrifugal blowers for ventilation and air-conditioning systems in nuclear facilities; and large axial-flow blowers for automotive wind tunnels.
Because advanced engineering expertise is required, each blower is custom-designed and manufactured to order. We provide an integrated end-to-end service―from design and manufacturing to installation and after-sales support.
Logistics systems are mainly used in manufacturers’ factories and distribution centers to manage products and support material handling operations. We provide solutions centered on automated guided vehicles (AGVs) that reduce the workload of operators and flexibly respond to fluctuations in logistics demand, as well as our “Rim Sorter,” which supports loading and handling operations.We also collect and accumulate operational data generated by these products and build IoT-linked systems that leverage this data for more efficient and optimized logistics operations.
Our testing systems business focuses on the development, design, and manufacturing of dynamic structural testing systems that support research into seismic behavior of structures such as buildings, elevated bridges, and nuclear equipment, as well as R&D for next-generation Shinkansen technologies aimed at achieving world-leading performance.Through these systems, we contribute to the reduction of earthquake damage and the improvement of operational safety for high-speed rail, helping to ensure a safer and more secure society. In recent years, we have also developed and deployed experimental systems that address long-period ground motions, which have caused damage to high-rise buildings in major earthquakes.

Ammonia is expected to become an effective solution for achieving carbon neutrality, as it emits no CO2 during combustion and its use as a fuel for power generation and marine transportation continues to expand. With extensive experience at ammonia plants around the world, our compressors contribute to reducing CO2 emissions.
The Edmonston Pumping Plant is a key facility that delivers water over approximately 1,100 km from water sources in Northern California to Southern California. To cross the Tehachapi Mountains, the system uses a water conveyance tunnel with an elevation difference of around 600 meters. Fourteen of the world’s largest pumps are in operation, delivering approximately 120 m3 of water per second.
Each pump produces about 80,000 horsepower-comparable to a jumbo jet engine. By introducing the latest high-efficiency pumps, the plant has achieved both energy savings and a stable water supply, while also improving overall reliability.
The Yamate Tunnel on the Shuto Expressway Central Circular Route Shinjuku Line is an underground tunnel approximately 11 km long, located about 30 meters below Yamate-dori Avenue in Tokyo. Its opening has helped disperse traffic and improve access to central Tokyo.
We installed ventilation equipment and an automatic control system for nine ventilation stations, supplying fresh air into the tunnel. Exhaust gas from passing vehicles is discharged through exhaust towers 40 meters above ground, creating a safe and comfortable tunnel environment.
This system reproduces earthquake motions dynamically and statically, enabling accurate evaluation of the seismic performance of structures and buildings at the design stage. With a long-stroke capability of ±1 meter in the longitudinal direction, it can simulate long-period ground motions.By clarifying seismic behavior of components such as tracks, bogies, and rail vehicles, the system contributes to R&D efforts including derailment prevention measures.
As global momentum toward decarbonization continues to grow, we are committed to creating environmental value across all industrial activities in society―including fuels and raw materials, power generation, power supply, and consumption. As a company that creates environmental value, we will work toward realizing a carbon-neutral society by providing products and services that reduce environmental impact.
We dispatch engineers to countries around the world, engaging in both short-term and long-term initiatives. Short-term activities include order-related meetings and participation in international conferences. Long-term efforts include equipment installation and preventive maintenance, as well as overseas training and study opportunities for young engineers. Through these efforts, we promote global technological exchange and aim to become a world-class team of engineers.
