powerMELA Hybrid Drive

Posted on March 27, 2013

Sensor-Technik Wiedemann (STW) is presenting its powerMELA hybrid drive for construction machines at bauma 2013.

The hybrid drive has been available for some time with a compact 140 kW motor-generator that weighs 130 kg and measures 510 x 300 x 415 mm, including the power electronics that are built directly on to the motor within the single cast housing.

The family of powerMELA is growing further as at bauma, STW will premiere a new smaller variant with an 80 kW electric motor. The new addition can be seen in action on a model compact diesel-electric hybrid loader. The recuperation of energy dissipated by deceleration is stored in a small lithium-ion battery and used to power the electric motor thus increasing the machine efficiency and reducing fuel consumption, STW said.
