The BAMA system (battery magnet plate system) is a specially developed solution for material handlers that is powered by a high-voltage battery. It provides a modular coupling between the traction battery and magnet plates by means of galvanically isolated DCDC converters and magnet plate control. This technology provides an efficient and flexible solution for use in material handling technology and ensures reliable and powerful magnetic force control.

Key features of the BAMA system:

Precise visualization of system data:

The HMI operating unit clearly and precisely displays all relevant system data, enabling easy monitoring and control.

Preset, selectable programs:

The BAMA system offers pre-set programs that enable fast and efficient work with different materials. These programs ensure precise adaptation to the specific requirements of material handling.

Monitoring the insulation of the magnet plate:

By using the galvanically isolated DC/DC converter, the insulation of the magnet plate installation can be monitored independently of other systems.

Adjustable magnetic force:

The magnetic force can be conveniently adjusted via the HMI control unit at the push of a button to achieve the desired holding force for the respective application.

Wide input voltage range:

The BAMA system operates in the input voltage range of 520-1000V, which makes it easy to connect to various high-voltage battery systems.

Easy connection to higher-level control systems:

Thanks to CAN bus-based communication (SAE J1939), GEMA components can be easily integrated into existing control systems, enabling seamless interaction with other systems.

Maintenance-free and self-protecting:

The BAMA system is maintenance-free and features self-protecting electronics that ensure maximum safety in the event of cable breakage, short circuits, undervoltage, overvoltage and excess temperatures.

The BAMA system is available in the following power classes: 10kW, 20kW, 30kW
