powerMELA®

Permanent Magnet Synchronous Motors

with Integrated Power Inverters

powerMELA®

powerMELA® is a compact drive solution for hyb-rid and electric mobile machines and vehicles. The proven system is already being used in many diffe-rent applications and was developed by Baumüller together with Sensor-Technik Wiedemann GmbH.

Functionality of the powerMELA® system

The powerMELA® drive concept consists of a perma-nently excited synchronous reluctance motor and

an integrated four-quadrant frequency converter. In the hybrid concept with powerMELA®, a DC volta-ge is generated in the vehicle electrical system by a combustion engine using a combination of generator and frequency converter. With all-electric solutions, operation is exclusively by battery current. The electric motors are connected to the on-board power supply and drive the vehicle.

Experience and spirit of innovation combined in the mobile drive concept powerMELA® —

electric power and drive tech for mobile work machines, ships and commercial vehicles

Reduced maintenance effort Fuel savings of up to 30%

Advantages of the powerMELA® system

Electric drives instead of hydraulic and rigid me-chanical solutions

Electric drives with high efficiency

Internal combustion engine at optimum operating point

Operating states largely decoupled

High power auxiliary units electrically operated

Good EMW properties

Additional insulation of the stator to the housing

Protection class II of the drive system in the IT network

No additional protective covers and filter mea-sures necessary

Environmental friendliness

Direct conductor cooling using rapidly biode-gradable transformer insulating oil

Long-term cost-efficient

Optimised performance

Highest power density by additional reluctance tor-que and direct conductor cooling

powerMELA-C 132/50, powerMELA-C 132/80, powerMELA-C 132/140

The powerMELA-C series is a family of permanent magnet synchronous electric machines with integrated power

inverters. They were developed specifically for mobile working machines, for use in both the main drive and

auxiliary drives. The machines are liquid cooled and designed for 4 quadrant operation. The desired values for

torque, voltage and speed control can be set over CAN bus.
