  • General industrial electric motors, power generation, wind power field

    Hitachi has been promoting the evolution of electric motors, a product that we have provided since our founding, through our design and production technologies supported by tradition over more than 100 years. As a result, the electric motors of Hitachi are used for various purposes as a key device supporting social infrastructure in a broad range of applications, such as in power generation, industry, and transportation. Furthermore, we have incorporated the advances in IoT and digital technologies in recent years to utilize Lumada, solutions of Hitachi for accelerating digital innovations, to analyze product operation information and develop diagnostic technologies that forecast when devices need to be replaced. With this integration of products and digital technologies, we will continue providing new value to suit the needs of customers throughout the entire lifecycle of products, from design to operation and maintenance.

  • Mobility field

    To meet the needs of high efficiency, size reduction, weight reduction, and reduced maintenance of the electric motors used in high-speed railways, such as the Japanese Shinkansen, we are utilizing our cutting-edge simulation and analysis technologies and the latest materials technologies to create products. With the increase in global awareness on the environment, we have positioned the railway business as a future field of growth, and we are also tackling design development for the next-generation electric motors. The technologies and knowledge we have fostered over many years in the areas of industrial and railway electric motors are also being applied to power generation and drive motors for mining dump trucks. In addition to a high degree of drive performance, we continue to provide stable operation, across the world, which can withstand even the harshest environments. Electrification is accelerating rapidly in the mobility field thanks to an increase in ESG investments. Hitachi will continue to proactively tackle new types of electrification by utilizing our assets of the technological capabilities and high reliability that we have fostered in global markets.

  • Distributed power sources and in-house power generation

    With the rising standard of living and growth of industrial activity, electricity has become essential. In case of a natural disaster, which could have a significant impact on essential utilities, stable power sources are necessary. In case of an unexpected blackout or natural disaster, Hitachi's in-house power generation units are highly reliable power sources as key devices that support social infrastructure.
    In addition to in-house power generators for emergencies, we offer highly efficient constant power generation units, such as co-generation power systems for saving energy and reducing CO2 emissions in factories and facilities. In this field, engineers are working in the fields of electricity, machinery, control and project management, and we are looking for people to work in these fields.

SIGNATURE TECHNOLOGIES SIGNATURE TECHNOLOGIES

  • Various industrial motors

    Since its establishment, Hitachi, which has supplied high-voltage large-capacity industrial motors for driving compressors, pumps and fans and motors for railway cars, has undertaken development to meet the changing needs of the times. The scope of development is broad, including temperature, vibration and noise, and we work as a team using various simulation techniques.

    Various industrial motors

  • Variable-speed AC motors for steel production

    Since the performance of variable-speed AC drive systems has significantly improved thanks to improvements in power electronics and control technology, the systems are used as a standard in steel plants today.
    With their quick response, high efficiency and larger field control area, many plants have greatly improved productivity and quality, increased ease of maintenance, and reduced energy consumption.
    Based on a wealth of experience and solid track record in motors for driving rolling machines, we produce and supply high-performance, high-quality and highly reliable variable-speed AC motors by using cutting-edge analysis technology and quality management in advanced production facilities.

  • Permanent magnet synchronous motor for railway vehicles

    Due to the demand for energy saving in recent years, the development of technologies to reduce the power consumption of railway vehicles is progressing. To reduce the power consumption of railway vehicles, it is important to reduce the power consumption during powering (acceleration) and increase the regenerative power consumption during regeneration (braking). In order to achieve these, it is effective to improve the efficiency of electric motors that drive the railway vehicles. We develop products that leverage on the strengths of the Hitachi Group, which has a wide range of railway business products, and conduct field tests on the actual railway vehicles the products will be equipped on, in addition to commercializing and supplying globally top-class high-efficiency permanent magnet synchronous motors to the market.

  • Power generators and motors for supersized dump trucks

    Super-sized dump trucks (300 - 500 tons) (gross vehicle weight) used for conveying mined natural resources are powered by electricity for the sake of controllability and performance. A truck is driven by an inverter control motor using electricity generated by the engine. We develop and commercialize generators and motors.
