Environmentally friendly and field-proven drives for agricultural machines

18.10.2019

Baumüller will be participating in Agritechnica in Hanover from November 10 to 16, 2019. The Nuremberg-based drive and automation specialist will be presenting its motors and systems in Hall 17 at stand H05a. At the trade fair, experts will present their achievements in the conception, engineering and development of individual drive concepts for agricultural technology.

Baumüller is making use of its many decades of experience in developing motors and producing electric engines, supplying energy-efficient components and comprehensive solutions for hybrid and fully electric drive systems. The low-noise, low-emission drive solutions are used in tractors, semitrailers, plowing machines as well as yard and wheel loaders.

Environmentally friendly and powerful alternative to diesel

Electric agricultural machines are a real alternative to diesel-powered vehicles. With their dynamic and powerful driving behavior, electric vehicles master the usual tasks with flying colors and they do this with long operating durations, flexible charging options and minimum noise pollution. Baumüller's engineering company, Baumüller Anlagen-Systemtechnik, designs and implements innovative drive concepts for mobile machines and implements them comprehensively, i.e. from battery management and the control system to the user-friendly user interface.

Baumüller equips both main drives and auxiliary drives, e.g. the hydraulic system in the bucket of a wheel loader, with its components and offers the option of integrating the BAUDIS IoT diagnostic and remote maintenance tool in addition to the electric drive system. In this way, necessary service measures can be planned in advance in a targeted way and operating times and loads can be optimally monitored and evaluated. This saves costs and enhances efficiency.

Intelligent drive solutions for agricultural machines

The powerMELA® drive concept, which Baumüller developed especially for mobile use in collaboration with Sensor-Technik Wiedemann GmbH, meets all the requirements for e-mobility thanks to its high power density, its compact and robust construction and its recovery capabilities. It consists of a combination of a permanent magnet synchronous reluctance motor, assisted by embedded magnets and an integrated four-quadrant converter. The compact design is firstly due to the integration of the converter, and secondly the compact construction of the electric motor. The drive’s innovative cooling concept enables an extremely high power density. The drive system thus requires minimum installation space and only weighs around 300 kg for the highest power category, including the motor, converter and transmission. The power density is thereby double that for motors using standard water cooling. With a degree of protection up to IP6k9k and a permissible temperature range.
