Voith has released details to their previously announced new system to power electric buses. The 260 kW permanent magnet motor was designed as a prototype for the Solaris Urbino, but is easily adaptable for buses from other manufacturers.
The liquid-cooled motor system also delivers a torque of up to 2,250 Nm. The energy for this is provided by a lithium-iron-phosphate battery, which Voith bought in from outside. The manufacturer added that the lightweight design helps minimize surplus weight, but also helps with noise reduction and energy consumption.
In the demonstration bus, which the company plans to present at the IAA in September, will have a range of “over 200 km”, according to the manufacturer. “The achievable range primarily depends on the battery, which we acquire from an internationally renowned supplier,” explains Jürgen Berger, project manager at Voith Turbo GmbH & Co. KG. “We are currently using a lithium-iron-phosphate battery. This battery offers the highest level of reliability, but the electric drive system is designed in such a way that it can work together with any battery technology.”
