• Compact construction through integrated power electronics 
  • Speed, torque and voltage control via CAN bus
  • Especially developed for use in mobile machines  
  • With integrated EMC concept
  • Easy system integration

The drives and generators of the powerMELA family are permanently excited synchronous machines which are available in a compact design due to the integrated power electronics. The oil cooling used, which is designed for high continuous performance, makes them ideal for use in mobile machines as generators or main and auxiliary drives. 
The machines have been designed for four-quadrant operation and permit the recovery of brake energy in battery-electric system architectures. The machines can be operated at setpoint values via CAN bus for the control of torque, voltage and speed. 
The combination of power electronics and the motor achieves high degrees of efficiency up to 95 % with continuous outputs of 80 kW and 140 kW.
In order to increase the power, two or more of the powerMELA electric machines can be combined using a summation gearbox. In this way, drives for larger commercial vehicles can also be realized. These drive packages can include sensors and control units with connections to the J1939 environment, and can be easily integrated into existing systems. 



We are proud of our products and solutions, but they really reveal their true colors when used by our customers. Whether digitalized, automated or electrified – mobile machines repeatedly delight with new innovations, in particular in terms of their user-friendliness, reliability and ability to integrate into work processes. Thanks to our customers, we are delighted to present a small selection here.


Our objective is to support our customers in all aspects concerning the digitalization, automation and electrification of their mobile machines. We consider the entire machine lifecycle and develop our STW product and service portfolio in alignment with this lifecycle. The ECO system, an open and holistic approach, facilitates the cross-topic integration of STW solutions. Furthermore, our product approach facilitates functional expansion through partner offers and hybrid, integrated products based on our system module.


The STW "ECO System" is characterized through the integration of systems and products which transcend the borders between solution areas. Our partners also supplement the STW product and services portfolio for the benefit of our customers. The open nature of the product portfolio permits easy integration of the products into third-party systems or the supplementation of our system through further products by third party providers.
