Variable frequency drives, motors and industrial gear units
26 Mar 2013
Bargteheide, Germany - At the 2013 Hannover Fair (Hall 15, Stand F26) NORD will again showcase its competence in complete mechatronic solutions integrating motor, gearbox, and drive electronics.
Concentrating on basic functions, the decentralised SK 180E frequency inverter is a solution for numerous elementary drive tasks such as long-distance horizontal conveying.
This inverter dispenses with features that are not strictly necessary, like positioning functions, encoder feedback, sophisticated safety functions, or braking resistors.
The robust, long-life design ensures the 200% overload reserves that are typical for NORD variable frequency drives.
Distributed technology follows a uniform operating concept with NORD CON parameterisation software available free of charge.
This enables, for example, efficient combined applications with a new electronically switched line of drives - SK 135E decentralised soft starters and reversing starters carry out simple switching tasks for motors from 0.25 to 7.5 kW which require no speed control.
They integrate extensive protection for the mains supply (current limitation), for the device (PTC/I²t, motor phases), and for the machine (torque limitation, overload).
Further additions to the NORD portfolio include efficiency class IE4 motors as well as the first line of smooth-surface motors. The latter will become available in the second quarter of 2013, with power output from 0.37 to 2.2 kW. These systems will also provide high efficiency rates corresponding to IE2, at minimum.
Notably, even very large models with output torques of up to 242,000 Nm are supplied without bolted joints or sealing surfaces. This design ensures supreme radial and axial load capacity.
