NORD DRIVESYSTEMS supplies application-optimised drive systems for compact mobile machine systems like pumps or fans up to 22kW. For variable speed operation of such machines that often have only one or a few drive axes, the NORDAC FLEX SK 200E frequency inverter can be directly mounted on the motor or close to the motor at the machine.

Even for mobile systems such as pumps for the wine industry or floor grinding and cleaning machines that have a manageable structure, pumped media often places high demands on drive control. The decentralised NORDAC FLEX SK 200E frequency inverter is suitable for applications such as mobile conveying or dosing in process engineering, and applications with similar requirements.

The inverter generates the control voltage itself, and can be easily and locally controlled and operated via switch and rotary potentiometer. Using the inverters integrated PLC, the device can perform minor logic functions autonomously. The NORDAC FLEX SK 200E demonstrates its high operational flexibility particularly with saving synchronous motors such as those required for continuous operation. In dosing application, the NORDAC FLEX can implement exact dosing requirements via the integrated POSICON positioning function.

High precision regulation at low speed

Frequency inverters from the NORDAC FLEX series are characterised by their high precision regulation. Extending into low-speed ranges, the drive control prevents strong turbulences. The drive systems ensure a high-resolution flow setting and, at the same time, can measure the density, temperature and volume of the media using external sensors. In addition, the inverter ensures smooth starting and stopping of the motor, enables self-regulating speeds adapting to specified pressure ranges with dedicated sensors, and provides effective protection against dry running.
