Hitachi Industrial Products’ state-of-the-art solutions are based on over 100 years of expertise. Our world-class engineering capabilities can be tailored to customers’ most specific demands. From product development to customer support and maintenance, we consistently meet a wide range of needs.
Starting with DC motors in 1911, Hitachi has been at the forefront of motor development for over a century. We made the motors that drive the Shinkansen bullet train (210 km/h) in 1964, and developed the Permanent Magnet Synchronous Motor (PMSM) in 2018 for greater efficiency and lower noise.
We design motors to meet the operational requirements of EMUs.
Designed with no air filter for easier maintenance, it eliminates monthly cleaning, saves time and achieves superior cost performance.
No cleaning of air filter (monthly)
Reduce cleaning of rotor dust (Overhaul)
Its closed design offers an extended maintenance cycle, in addition to reduced noise.
Maintenance cycle can be extended
Noise is reduced by 20%
(compared to open air model)
The bearings can be replaced without disassembling the rotor, making maintenance work more efficient.
Bearing replacement time is reduced by 70%
compared to not applying this feature
This design provides much higher efficiency than copper motors, along with smaller size and full torque at low speeds.
Achieves 98% efficiency
Better LCC (Life Cycle Cost) and good practices for SDGs
Motor accessories (provisions) for IoT solutions are available on our traction motors.
The progress of IoT solutions in recent years has led to a greater demand for monitoring signals from motors. HIP motors can be outfitted with all types of sensors to meet customers’ monitoring requirements.
In recent years, Condition Based Maintenance (CBM) has been gaining attention as a strategy for improving efficiency in maintenance work.
At HIP, we are working on development and practical applications for technologies that support CBM.
Conventional maintenance is called TBM (Time Based Maintenance), as parts replacement and other maintenance is performed based on time elapsed.
This requires operational knowledge to determine when parts need to be replaced. It also requires visual inspections to prevent sudden failures.
Why is CBM gaining attention? It monitors vehicles using sensors instead of human inspection. And it can detect possibilities for sudden or unexpected failures before they happen. This can extend the maintenance cycle by optimizing the replacement schedule.
Maintenance manual can be provided in multiple languages.
On-site maintenance training courses are available.
Spare parts and motors can be supplied long into the cycle.
Technical support is available 24/7 by phone and e-mail.
