KeolisAmey Docklands adopts Perpetuum’s innovative self-powered rail condition monitoring for traction motors

Perpetuum, the global leader in vibration energy harvesting and its application in asset management across the rail industry, has announced it is working with KeolisAmey Docklands (KAD) to monitor the condition of its traction motors while they are in service and improve the reliability of its assets on the high availability Docklands Light Railway (DLR).

Perpetuum secured a contract with KAD in 2015 and has consequently worked with the KAD engineering team to reduce the turnaround on railway assets for maintenance and renewals. The results have been extremely positive and Perpetuum’s technology is installed on 20 traction motors on five trainsets. KAD’s decision to mount sensors at the vibration source on the train is providing the earliest possible alerts to bearing failures, allowing the system to improve safety across the fleet. As the busiest light railway in the UK with more than 115 million passenger journeys in 2015, KAD has a responsibility to continue delivering excellent service and customer satisfaction, while maintaining and improving upon 99% departures passengers are accustomed to. “This deployment of remote condition monitoring is part of a larger KeolisAmey Docklands policy of moving its maintenance methodology towards a data-driven and real time operation,” explains Dave Smale, Engineering Director for KAD.


“This is an industry-leading solution; a first for the rail industry that incorporates the use of vibrational energy harvesting powered system to measure traction motor bearing degradation and report it as a single index,
Motor Health Index (MHI). The successful implementation of the technology on other projects means that it can be expanded to monitor other systems on the train.”

“This pilot marked Perpetuum’s first step into the metro market as we continue our rapid expansion across the rail industry,” explains Justin Southcombe, Commercial Director for Perpetuum. “More and more operators are adopting our unique technology, using our depth of knowledge and mining our extensive data analysis capability to save cost and make asset management more effective. Other train companies are now also exploring the technology here in the UK and around the world. “Traction motor bearing failure has been an on-going issue for most railway operators which causes train failures in service as well as the cost and impact of early bearing failures, resulting in dissatisfied passengers and reputational losses.”

Powered by its innovative wireless energy harvesting micro-generators, Perpetuum’s onboard Sensor Systems produces powerful vibration and temperature data, enabling its clients to accurately view the real time health and predict the failure of rotating components on trains, such as wheel bearings, motors and gearboxes. Perpetuum’s innovative solution has already been proven amongst other UK and offshore fleets, as well as other parts of the wider Keolis family, such as Thameslink, Southeastern and Southern, part of the GoVia joint venture.
