NORD Drivesystems LogiDrive modular drive concept

NORD Drivesystems creates individually tailored drive solutions for intralogistics applications based on the LogiDrive concept, said to be 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 that 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 the LogiDrive concept’s energy efficiency and reduction of variants may be further optimised.

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 lifecycle. 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 possible with LogiDrive concept synchronous motors as they operate independently of load and speed.
