Novel plug&play drive design facilitates installation and operation

On the occasion of its tenth anniversary, NORD DRIVESYSTEMS S.A. de C.V. Mexico opened a new, larger assembly plant and office in Huimilpan, in the state of Querétaro, Mexico.

NORD DRIVESYSTEMS portfolio already exceeds EU Ecodesign stipulations

NORD DRIVESYSTEMS has committed INR 45 mn (approx. EUR 600,000) to the expansion of its Indian subsidiary. The investment was used to establish a new service area at the NORD DRIVESYSTEMS Pvt. Ltd. facility in Pune. The factory now boasts a 13,000 m² shop floor and can turn out over 24,000 drives per year. Since 2005, the company has delivered more than 100,000 geared motors to customers across the subcontinent. Short delivery times and fast service are among the most important measures to keep regional customers satisfied. Staffed with a team of experienced, highly trained technicians, the new, expanded service area is crucial to ensure this for the future. In addition, NORD has launched an initiative for service vehicles: they serve customers on location, quickly provide qualified customer service, and are even equipped to offer training.

Enabling centralized as well as autonomous operation

NORD DRIVESYSTEMS now offers standardized drive units in three highly efficient and easy-to-service versions for typical requirements in conveying applications. The line-up of LogiDrive systems enables a quicker selection of the suitable drive for a given application and allows for reducing the variety of versions to a manageable few. IE4 synchronous motors with 1.1 kW, 1.5 kW, and 2.2 kW rated power are combined with two-stage helical bevel gears for speed ranges of 0-565 rpm (size 1) or 0-482 rpm (size 2 and 3). The transmission is continuously variable in the range from 1 to 500. Distributed frequency inverters for installation on the conveyor frame near the motor ensure optimum accessibility. They feature a key switch for disconnection from the plant control system and a direction switch for local set-up.

NORD DRIVESYSTEMS presents the newly developed NORDAC LINK series field distribution systems. These new AC vector drives and motor starters are in the final phase of field tests. Serial production will commence early in 2017. Coded plug-in connectors for power, communications, sensors, and actuators enable fast, safe installation and commissioning. LEDs that indicate switching states, operation modes, and signal states allow operators to diagnose errors directly on site. Maintenance and control switches on the device facilitate plant servicing and system set-up. Designed for flexible configuration, NORDAC LINK drives are especially suitable for conveying applications, but can also be used with other machines and systems. Integrated functionality ranges from rotary encoder support and brake management to PI control and sequence control through an integrated PLC. The drives feature a high overload capacity. They enable very precise control of either asynchronous or synchronous motors and reliably deliver full torque even at zero speed. Moreover, the drives provide extensive monitoring functions to protect the mains, the motor, and the driven machine. Power supply can be daisy-chained from one drive to the next. This greatly reduces the cabling effort and costs, particularly in complex applications with hundreds of drive axes.

Smooth-surface motors in the malt house

Bargteheide – Intelligent drives from NORD DRIVESYSTEMS with an integrated PLC are fully equipped to execute control sequences in customer applications. Featuring numerous sensor interfaces and extensive diagnostic as well as process control functions, they can detect blockages and in many cases independently restore normal operation. This improves system availability and reduces servicing requirements. If the drive is able to remove an obstacle, such as a blockage in a pipe, by repeatedly changing the motor speed and direction, it will then resume normal operation. If the problem persists, the inverter can submit an error signal to the control level and possibly initiate a fallback procedure, for instance by having other networked drive units unlock a bypass. Any such measures can be programmed individually specific to an application. This gives users independently operating, intelligent plant segments and machinery such as sorters, portioning and packaging systems, single pumps or groups of pumps, crushers, or screw conveyors. At the same time, optimum integration into automation networks is ensured. The inverter PLC can pre-process drive and application data for a higher-level controller for various uses including diagnostics. NORD provides low-maintenance, versatile distributed drive electronics with exceptionally good electromagnetic compatibility for synchronous and induction motors up to 22 kW.

NORD DRIVESYSTEMS, a leader in drive technology, has engineered an industrial gear unit with 240,000 Nm rated torque load and various application-specific features for a phosphate mine in Morocco. It is to date the largest system with a one-piece gear case.
