Energy efficiency and reduction of variants


Individually tailored drive concepts based on the LogiDrive system solution from NORD DRIVESYSTEMS represent an optimal compromise between energy efficiency and a reduction of variants. They prove themselves in major intralogistics projects for airports or parcel centres where a large number of drive units are installed.

NORD DRIVESYSTEMS creates individually tailored drive solutions for intralogistics applications based on the LogiDrive concept – an energy-efficient, service friendly and standardised modular system. LogiDrive drive units consist of an IE4 synchronous motor with rated powers of up to 5.5 kW, a two-stage helical bevel gear unit and a NORDAC LINK frequency inverter which is installed close to the motor. The entire system has a modular design, so that all components of the drive technology can be individually serviced. With the latest IE5+ synchronous motor from NORD DRIVESYSTEMS the LogiDrive concept’s energy efficiency and reduction of variants may be further optimised.

Optimal energy efficiency and reduction of variants
Planning a system with drives that are designed for the most energy-efficient operating points leads to optimal investment costs and motors operating comparatively energy-efficiently, independent of their efficiency class. For this purpose, many different drive variants must be managed and serviced during the system’s entire life cycle. A reduction of variants aims to provide an economically viable coverage of the required speeds and torques within a system, using a minimum of different drive variants. If required, NORD provides this optimisation service in the context of customers’ projects. Variants may be reduced by using only one geared motor and frequency inverter size for a specific speed and load range. Controlled via the frequency inverter, this drive unit may then cover all required operating points for lower performance requirements or other speed ranges. This is easily possible with LogiDrive concept synchronous motors as they operate independently of load and speed.
