Baumueller (Germany) exhibited in Hanover solutions for hybrid and electric powertrains. The products feature CAN connectivity.
At the Agritechnica tradeshow, Baumueller presented an electric municipal vehicle at its booth. Two electric drives were mounted to the rear axle of the vehicle. Each drive system consists of a DSA synchronous external rotor motor with integrated inverter. Baumueller also designed and implemented the drives for a loader. The loaders typically driven with combustion engines also operate hydraulic cylinders via the diesel drive, for the bucket for example. For one order, both the traction drive as well as the drive of the hydraulic cylinders were completely converted to be fully electric.
For mobile use, the B Maxx mobile controller is vibration resistant and can be used in temperatures between -25 °C and + 65 °C. For example, the controller is suitable for use as a wheel-hub drive with DSM disc motors.The integration to the in-vehicle networks is supported by the CAN interface.
The Powermela drive concept meets all the requirements of the electric mobile drive technology. The motor offers a high power density due to its direct cooling concept. The drive system thus requires minimum installation space and weighs around 300 kg with the motor, inverter, and transmission. In addition, the supplier has designed the permanent magnet synchronous motor with deeply buried magnets. The motor is available in the performance classes of 40 kW, 80 kW, and 140 kW.
The Baudis IoT system optimization tool helps to improve the efficiency of the drives. The networked system consists of sensors, a Baudis IoT box and software. The IoT system monitors the process data of the drive, such as the motor status, power peaks, and runtime. The data is collected in the Baudis IoT box and passed on to a local server or a cloud server. The performance data is analyzed and visualized there with the provided IoT software. By using this IoT approach, for example, benchmarks can be set and the electric drive and load cycles can be optimized. The evaluation always occurs with the latest available algorithms. The system can be used independently of the manufacturer of the motor and automation devices and sensors. This means you can retrofit and upgrade vehicles.
