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, to develop individual drive concepts for agricultural technology.
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.
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 from – 40 °C to 85 °C, the drive is especially robust. The motor design is also characterized by a broad speed control range, due to its excellent field weakening capacity.
The motor is available in the 50 kW to 140 kW nominal power classes. Alongside direct use in vehicles, the powerMELA® is also ideal for other applications, such as for trailers.
