In Hannover Nord Drivesystems has presented drive electronics, efficient motors, including the manufacturer’s first smooth-surface motor line, and the latest additions to the Unicase series of industrial gear units. Concentrating on basic functions, the decentralised SK 180E frequency inverter is suitable 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 200 % overload reserves.
Nord’s fistributed technology follows a uniform operating concept with Nord Con parameterisation software. This enables, for example, efficient combined applications with an 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).
