ABB says its AMXE250 motor and HES580 inverter are perfectly matched for bus drivetrain solutions. ABB

ABB announced the launch of a new package consisting of an AMXE250 motor and HES580 inverter which it says has been tailored for electric buses. ABB says the HES580 inverter is the first 3-level inverter in the market for electric buses and boasts superior energy efficiency and power output. Compared to conventional 2-level inverters, the manufacturer says it achieves a substantial reduction of up to 75% in motor harmonic losses, significantly minimising heat dissipation and maximising energy conservation.

The firm adds that the HES580 not only demonstrates up to 12% fewer motor losses on typical drive cycles compared to conventional 2-level inverters but also significantly benefits the AMXE250 motor by extending its lifespan and enhancing its reliability. By mitigating harmonic effects and minimising stress on motor windings, ABB believes that its inverter and motor combination offers sustained performance and longevity of the entire electric drivetrain.

ABB Traction Division Global Product Manager David Segberssaid: “We’re delighted to bring the first 3-level inverter for electric buses to the market. The motor-inverter package has been designed to work in perfect harmony and will bring significant energy efficiency gains for operators and OEMs alike.”

Global Head of Mobile e-Power at ABB Fabiana Cavalcante added: “Electrifying buses in this way is a key part of bringing sustainable, clean public transport that improves the quality of life. We’re thrilled to provide future-proof solutions that helps the industry to meet their sustainability and performance objectives.”
