Ingeteam has received an order from Stadler to supply traction converters for 16 BEMUS (Battery & Electric Multiple Units) that will run on the Kamptalbahn line in Austria, reaching a maximum speed of 160 km/h (140 km/h under battery). The contract includes options for a total of up to 120 vehicles.
For each train Ingeteam will deliver two roof-mounted, water-cooled traction converters. The equipment is specially designed to ensure efficient operation on non-electrified tracks, thus promoting sustainable transportation. Particular emphasis has been placed on ensuring easy maintenance to guarantee safe operation.
These converters integrate all essential components — such as the traction inverter, brake chopper and line converter— to be fully operational.
The traction converters are designed to operate with dual power sources, drawing electrical energy either from the overhead catenary system (15 kV AC and 25 kV AC, depending on the line) or from onboard battery systems when running on non-electrified sections. The system converts the incoming power into the appropriate voltage and frequency required to supply the traction motors.
Moreover, Ingeteam will conduct comprehensive traction system tests to validate the performance of all key elements: converter, motor and energy storage system. These tests, performed at Ingeteam’s Electromobility Laboratory feature a customized set-up tailored to the specific requirements of the project, and help reduce commissioning time, since all parameters are fined-tuned in the laboratory.
Manufacturing will be carried out at Ingeteam’s Ortuella (Bizkaia) facilities, with all deliveries expected to be finalized by 2027.
In total, more than 90 traction converters of this configuration are planned for production across different BEMU projects, including this one.
This milestone reinforces Ingeteam’s strategic positioning as a key player in the development and deployment of advanced, sustainable traction technologies for the railway sector.
