with their heavily ribbed housings are well suited for this purpose. The power and speed ranges of the application-optimised two-stage right-angle gear units have been specially designed for applications in which low speed ranges are required in combination with high power. MAXXDRIVE ® XT series output torques range between 15 and 75 kNm with speed ratios of 6.3 to 22.4. The industrial gear units are available in seven sizes for a power range from 50 to 1 500 kW. Other typical applications for this range of strong industrial gear units include mixing and agitation processes. By equipping the com- pact and robust MAXXDRIVE ® industrial gear unit with reinforced bearing and flange versions (VL2/KL2 - VL6/KL6), the drive can be optimally adjusted to application loads. Sealless IEC/NEMA adapters (SAFOMI) and a True Drywell sealing at the output shaft provide for high operational reliability. The whole drive system – from NORD elec- tric motors to flange connections – is delivered as a ready to install unit, which can easily be mounted vertically on the application. Networked maintenance NORD also offers innovative predictive maintenance concepts de- signed for the MAXXDRIVE ® industrial gear units. The NORD frequen- cy inverter is an essential component here. Status data available in the inverter can be communicated to higher-level control or directly to a safe cloud. The inverter can also directly record external sensor data on vibration monitoring or measuring the gear unit’s oil sump temperature. Changes to the system condition can be detected at an early stage and predictive maintenance can be scheduled in good time. reduces operational costs. The solution is tried and tested and has been run successfully by customers for over seven years. Additionally the system offers the following advantages: - The Single Line Network principle means only one cable needs to be installed for energy and information transfer - Simplified system planning and design - Reduced number of variants due to wider speed range and universal mounting position - Lower storage costs For more information visit: www.nord.com - Reduced energy costs due to high efficiency of all components - High reliability due to systematic development of all components - Reduces total and operating costs of the materials handling system - Built-in Profinet communications protocol forms part of the MOVIGEAR ® system and reduces the need for extra topology as there are fewer moving parts. “MOVIGEAR ® has proven its reliability anddemonstrated significant benefits for clients in Europe,” says Strydom. “A large bottling plant, for example, was able to boost production to 60 000 bottles per hour, and a beverage packaging plant was able to drive savings through energy efficiency. In South Africa, SEW-EURODRIVE is confident that this solution will continue to provide impressive cost, production and energy efficiencies for our customers across key sectors,” he says. - High degree of protection - No air, dirt, or germ swirls
