Concentrated e-power for agricultural machines
| PI 034/23
With the EMP eLION motor series from Bosch Rexroth, off-highway manufacturers can build even more compact and powerful machines
- High power density saves space in the machine
- Optimized for travel drives, working hydraulics and generator operation
- Ideal for machines where space is limited
Bosch Rexroth has expanded its eLION electrification portfolio with the compact EMP series of high-torque motors. It allows greater precision and a high power density in self-propelled and towed agricultural machines as well as other off-highway vehicles. The new series of motors is suitable for electrifying travel drives, as a pump drive for the implement hydraulics or as a generator, e.g. in diesel-electric architectures. With high torques and various speeds, the EMP motors provide optimum support for all drive types including those with new power sources. Significantly reduced torque ripple also increases control efficiency and battery life by generating torque evenly.
In modern off-highway machines, motors and inverters are concentrated in the smallest of spaces. With the new EMP eLION electric motors, Bosch Rexroth supports highly optimized machines such as tractors, self-propelled machines and towed equipment by reducing the space required for the same power or by providing more power in the same space. Existing ranges can also be electrified with minimal changes to the vehicle chassis.
Like all components of the modular eLION platform, the new EMP motors meet all the requirements for off-highway use as regards mechanical resistance, service life and resistance to vibrations, dust or chemical substances.
The torque spectrum for the EMP series ranges from 160 to 880 Nm. Compared to the proven EMS series, the rated torque at lower speeds is up to 53 percent higher, and the maximum torque is up to 45 percent higher. At the same time, torque ripple has been reduced by over 30 percent. As a result, high torques are produced very evenly, even at low speeds, which allows better control of the electric drive and improves battery life. The high system efficiency and intelligent energy management also reduce electricity consumption and thus the operating costs too.
The EMP motor series is the latest development in the scalable eLION high-voltage electrification portfolio for driving and working functions. The modular platform includes other components too – not only inverters and gearboxes but also software and accessories along with tailored hydraulics. Fully integrated functional safety in accordance with ISO 13849 in all inverters helps to save time during engineering.
The new EMP series will be available from 2024 in five lengths and in the power range from 30 to over 200 kW.
The eLION portfolio is already used in numerous pilot applications, for example in the “Process Unit” (VTE) developed by the agricultural machine manufacturers KRONE and LEMKEN. The powerful drive ensures that the autonomous traction unit can easily cope with a wide range of work processes such as seedbed preparation, cultivating, hoeing, mowing, turning or swathing.
