NORD presentation at logistics exhibition focuses on intelligent drive concepts
Bargteheide – At the LogiMAT 2014 exhibition, NORD DRIVESYSTEMS will showcase economic mechatronic drive systems consisting of two-stage helical bevel gear units, high-efficiency motors, and decentralized drive electronics. Their functional range is scaled according to the application: the electronic starter SK 135E enables constant speed as well as reversing operation. The SK 180E frequency inverter controls the speed of horizontal conveyors. The SK 200E series performs drive tasks in lifting, lowering, and inclined conveyor applications, providing high dynamics even with heavy loads. Mounted on top of or close to the motor, these inverters cover motor performances up to 22 kW and can also be used for regenerative operation thanks to a brake chopper and a braking resistor.
With this product portfolio, NORD implements efficient drive concepts that support a straightforward variant management. The exhibition model demonstrates, amongst other things, contact-free and gap-free baggage accumulation. Motor encoders and sensors are wired directly to inverter. In order to seamlessly transfer transported goods to the lifting mechanism, the various drive units are synchronized. The proven ISD vector control enables high dynamics and steady operation even during heavy load fluctuations. An overload capacity of 150% for 60 s and 200% for short periods ensures increased reliability and a long service life. In the exhibition model, the controller and the drives communicate via Profibus. In addition, NORD provides other industry standard communication options such as Profinet or EtherNet/IP.
