The Vorecon variable-speed planetary gear provides speed control with maximum reliability and low lifecycle costs. With the new NX series (photo), this company has now further developed the proven principle specifically for applications in the low power range (up to 10 MW). The Vorecon NX provides an increase in efficiency of up to 8% in part load. In the new series, an optimized torque converter provides efficient speed control, which uses only a small portion of the input power. Depending on the speed required, this power is fed back to the driveline by way of the planetary gear on the driven side. Adjustable pump blades in the torque converter provide stepless and wear-free control. — Voith Turbo, a Group Division of Voith GmbH, Crailsheim, Germany
