Bosch has introduced an advanced 800-volt electric drive system designed for construction machinery with high power demands at the bauma 2025 exhibition. The system includes the Bosch SMG230 electric motor and an efficient inverter using silicon carbide power modules. Designed to operate at voltages between 400 and 850 volts, the motor offers up to 200 kilowatts of continuous power and 250 newton meters of torque. For short bursts, the system can provide a peak torque of 550 newton meters.
Thanks to the 800-volt technology, the system significantly boosts power density. Compared to a similar 400-volt machine, it delivers up to 80 kilowatts more power with the same weight, or a more compact design and lighter weight at the same power level. The silicon carbide-based inverter, tailored specifically to the SMG230, boasts an impressive efficiency of over 99%, enabling faster switching and reducing energy loss as heat.
Bosch Engineering’s electric drive components for construction equipment are designed to be robust, reliable, and durable, meeting the rigorous standards of mobile machinery. The compact size of the system allows for easy integration into tight spaces, making it possible to retrofit existing platforms with eco-friendly electric drives. Bosch also supports its clients with the integration and application of the system into their machinery.
Additionally, Bosch will present the new Rexroth eGFV9100 coaxial gearbox, specifically paired with the SMG230, at bauma at booth A3/327. Bosch Engineering, in collaboration with Bosch Rexroth, also aids in integrating the electric drive into construction machinery, with development support based on the open ECOsystem BODAS.
