Danfoss VLT One Gear Drive Powerful Efficient and Hygienic User Guide

Energy-efficient, flexible, reliable

VLT® OneGearDrive® comprises a highefficiency permanent magnet (PM) motor coupled to an optimized bevel gearbox. As part of the Danfoss VLT® FlexConcept® the drive is an energyefficient drive system that helps to optimize plant productivity and reduce energy costs. The VLT® FlexConcept® comprises the VLT® OneGearDrive®, combined with a VLT® Decentral Drive FCD 302 or VLT® AutomationDrive FC 302.

Cost reductions with drive control
The VLT® OneGearDrive® features a PM motor, which is a three-phase synchronous non-salient motor. With an efficiency of 94.9% the motor achieves the IE5 Ultra Premium Efficiency Class defined in IEC TS 60034-30-2 while providing high torque in a compact motor frame.

With only one motor type and three available gear ratios, the motor concept covers all typical versions of conveyor drives commonly used in the food and beverage industry.

For conveyor drives in particular, this system dramatically simplifies projects whether the plant operator prefers a centralized or decentralized solution.

Optimized components ­ fewer variants
The VLT® OneGearDrive® uses optimized bevel gearing, which is more efficient than commonly used worm gears. As a whole, the system of gear motor and AC drive can reach an efficiency level of 89%, yielding energy savings of up to 40% compared with conventional systems. The system components allow maximum flexibility with a minimum number of unit variations such as motors, gear unit sizes or AC drives, all of which offer a uniform user interface concept and the same functionality. A reduced number of geared motor unit (GMU) variants across the plant also means smaller spare parts inventories and further cost reductions.

Flexible solutions ­ high efficiency
Electric drives play an important role in supporting food and beverage operations to optimize plant efficiency and reduce energy costs. The VLT® FlexConcept® takes this effort a crucial step further.

Savings in operations and maintenance
In the past, the various production areas: manufacturing, filling, packaging, palletising, and storage required a variety of drive concepts. For example, dozens or even hundreds of drives were needed just to power the conveyors interconnecting the various production stages.

Previously, motors were not particularly efficient; there was a wide variety of transmissions and drives in use and maintenance costs were high. The consequences were, and still are, high energy costs and maintenance of large stocks of spare parts in order to minimize down-time. Since then, the evolution of variable speed drives has brought the drive/motor combination to a high peak of performance, capable of matching that of even servo drives.

With the VLT® OneGearDrive® as part of the VLT® FlexConcept®, Danfoss has developed a flexible, standardized and efficient drive system that significantly reduces the number of drive variants, resulting in greatly reduced operating costs, substantial energy savings and carbon dioxide reductions.

Hygienic design required
Especially in food and beverage production areas, but also in pharmaceutical and cosmetic manufacturing plants, hygiene compliance rules are extremely demanding. This is why Danfoss has designed the VLT® OneGearDrive® to comply with the specifications and guidelines for the comprehensive, proactive protection of food from contamination with bacteria, fungi and yeasts during processing.

In the VLT® OneGearDrive® Danfoss has utilized years of experience in process and mechanical engineering, as well as knowledge in microbiology, to create a competitive, cost efficient solution that can easily be integrated into any production setup.

This is a clear advantage compared to upgrading existing process equipment designs to meet hygienic requirements, which is often both expensive and unsuccessful.

Use fewer variants ­ run a higher number of applications

VLT® OneGearDrive® ­ one gear size
Compared to traditional systems, the compact design of the VLT® OneGearDrive® makes it a strong choice that can provide benefits in transport and conveying systems as well as machines and equipment.

With only one motor type and three gear ratios available, the motor concept covers all typical conveyor drives. Furthermore, the restricted range of physical configurations of the VLT® OneGearDrive® simplifies spares holding and makes it more cost efficient, easing engineering and installation thanks to uniform mechanical dimensions.

Flexible plant design
In combination with the VLT® AutomationDrive FC 302 or the VLT® Decentral Drive FCD 302 the VLT® OneGearDrive® is equally suited to central and decentral installations, giving the plant designer complete flexibility from the outset.

A high breakaway torque is obtained and three gear ratios (5.92, 14.13, 31.13) are available. With a cable length of 150 m (screened) and 300 m (unscreened) between the drive and VLT® OneGearDrive®, all conditions for conveyor drives in the food & beverage applications are fulfilled.

Less expensive, fewer variants
Due to the PM motor there are lower losses, a smaller moment of inertia, a wide torque and speed range and a high short-term overload capability, enabling high maximum torque over a wide speed range. This gear motor is a drive which, considered over its lifetime, is less expensive than conventional geared motor units (GMUs).

Long service intervals
The VLT® OneGearDrive® runs 35,000 operating hours in partial operation between oil changes (by using food grade oil). This means long service intervals, low maintenance costs and effort, and low operating cost.

Up to 40% energy savings
achieved, compared to conventional systems by using VLT® OneGearDrive® together with a VLT® AutomationDrive FC 302 or VLT® Decentral Drive FCD 302

Dry, wet and washdown aseptic areas
The VLT® OneGearDrive® comes in two versions, the VLT® OneGearDrive® Standard for use in dry and wet production areas while the VLT® OneGearDrive® Hygienic for use in aseptic areas heralds a new threshold in food hygiene and cleanability.

Hygienic design

Food safety
In food and beverage production areas where the product may come into direct contact with equipment and motors, the hygienic design of process equipment has a tremendous impact on diminishing the risks of contamination, which also means that the shelf life of products is improved. If the applied process equipment is of a poor hygienic design, it is difficult to clean it of micro- bacterial contamination.

New hygienic trends
EU regulations for the compliance of hygienic equipment to be used in the manufacture ring of popular food and beverages are becoming increasingly tight. For example, in the beverage industry, still water, fruit juices and alcohol free beers are all highly reactive to external influences.

New packaging materials also raise the demands on the hygienic conditions. Plastic packaging for cosmetics, including PET bottles in the drinks industry, require new measures as they do not tolerate heat sterilization or cleaning that previously rendered glass containers aseptic.

Hygienic design
After years working with the food and beverage industry, Danfoss knows better than most the need for a robust, watertight construction that resists attack by acids or detergents, doesn’t harbour bacteria and can be cleaned down quickly and easily, shortening the maintenance window.

The VLT® OneGearDrive® Hygienic has a completely smooth, easy to clean surface, with no cooling fins, fan, or pockets. This design prevents bacteria growth and allows detergents to drain off freely.

Completely smooth surface
The VLT® OneGearDrive® Hygienic has a completely smooth, easy to clean surface, with no cooling fins, fan, or pockets. This design prevents bacteria growth and allows detergents to drain off freely.

Because these drives do not have fans, they do not suck in airborne germs and blast them back into the surrounding air. The drive units are also available with totally encapsulated brakes.

High degrees of protection
The VLT® OneGearDrive® Hygienic is resistant to detergents and disinfectants (pH 2 ..14). Danfoss supplies the VLT® OneGearDrive® Hygienic with high IP67 or IP69K ingress protection ratings as standard. A proven stainless steel plug-and-socket connector simplifies replacement during maintenance.

IPA certified
The VLT® OneGearDrive® Hygienic is certified as usable for clean rooms and aseptic filling by IPA (Fraunhofer institute) according to the dedicated “Air Cleanliness Classification” DIN EN ISO 14644-1.

The VLT® OneGearDrive® is designed to be integrated in the plant equipment and to withstand the same detergents and physical cleaning as the rest of the aseptic production equipment.

Two versions are all you need
