Ingeteam has received an order from Stadler to supply traction converters for 16 BEMUs that will run on the Kamptalbahn line in Austria, reaching a maximum speed of 160 km/h and 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. They integrate all essential components - such as the traction inverter, brake chopper and line converter. They are designed to operate with dual power sources, drawing electrical energy either from the catenary of 15 kV 16.7 Hz or 25 kV 50 Hz, or from on-board 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.
Particular emphasis has been placed on ensuring easy maintenance to guarantee safe operation. 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.
