    System changeover - with maximum safety ensured through a complete e-drivetrain solution from a single source

    The Voith Electrical Drive System (VEDS) is an electric direct drive system for OEM independent city bus (solo, double deck, school, and articulated buses) and coach applications with both battery-electric and fuel cell electric power sources. It combines a water-cooled permanent magnet motor with an inverter and control software; further auxiliary components are optionally possible. With the integrated system approach of the VEDS, all system components are perfectly aligned with each other. It begins with hardware components such as electric motors, traction inverters and high-voltage distribution systems, and extends to software components such as drive control and energy management.

    As a result, the drive system provides a low-weight solution with its compact design, enabling a lower energy consumption during operation and a range increase. Performance is another key factor. With a torque of 3,100 Nm and a power of 310 kW (continuous power) the heavy-duty (HD) direct drive electric motor is suitable for solo buses, heavy articulated or double-deck buses. The medium duty (MD) electric motor shows a torque of 2,850 Nm with an output of 230 kW (continuous power), suitable for medium-duty buses.

    Quiet, reliable, and powerful - the innovative e-drive system

      VEDS small scope
      VEDS small scope provides the basis components of an e-drive system for different bus applications. It consists of an electric motor, a traction inverter, and corresponding drive management unit.
      Voith supplies different electric motors and inverters depending on the customer’s bus application. The customer can choose between the medium duty and heavy duty motor variant.
