Bonfiglioli presents electric drives

Bonfiglioli has developed a modular electric drive system, based on a new development of a series of permanent magnet electric motors with a Bonfiglioli typical housing design in connection with the proven design principles of planetary gears.

The new electric drive series is scalable in three diameters, each with several lengths of the electric motor. The concept thus allows a power range of 4 to 150 kW. With the motor diameter of 230 mm (presented at bauma 2022, in A3.337) three lengths with 4, 7.5 and 15 kW are available. Further diameter/length combinations are in preparation.

Bonfiglioli said, the new electric drive system retains the basic technical properties and robustness of Bonfiglioli traditional products and has the wide range of power and torque that is particularly appreciated by machine builders.

Bonfiglioli’s IoT experience also plays a role with specific hardware and software products. Connectivity, models and analytics, edge computing and gateway technology up to the cloud with corresponding dashboards for the user are available.

The electric drives, which can be used as travel and swing drives, are designed in principle in such a way that, like their hydraulic models, they have all the technical necessities and properties. The electric motor in its robust housing is air-cooled and corresponds to protection class IP67.

The core of the drive, the permanent magnet motor itself, is equipped with temperature and speed sensors and is maintenance-free. A single or multi-stage planetary gear is flanged directly to it, which is defined according to the requirements of the machine manufacturer. Its maintenance intervals are long, and maintenance itself is very easy thanks to the smart design.

According to Bonfiglioli, 50% of all new self-propelled construction machines will be either electrically or hybrid driven by 2030.
