Features and Benefits
The VLT® OneGearDrive comes in two versions, the OneGearDrive StandardTM for use in dry and wet production areas and the OneGearDrive HygienicTM for use in wet areas, areas with high cleaning intensity and aseptic and clean room production areas.
The perfect solution
The compact design of the VLT® OneGearDrive makes it predestined for use in transport and conveying systems as well as machines and equipment. The drive has been designed especially for use in the food and beverage industry although it offers significant benefits in all conveyor drive applications.
One gear size – covers all application – reducing spare parts inventory
Compared to traditional systems, the VLT® OneGearDrive covers all applications with one drive size and a minimal number of variants, reducing spare parts inventory and easing engineering thanks to uniform mechanical dimensions. With only two motor types and three available gear ratios, the motor concept covers all typical versions for effective conveyor drives commonly used in e.g. the food and beverage industry.
High system efficiency
The VLT® OneGearDrive also uses optimised bevel gearing, which is more efficient than commonly used worm gears. The system as a whole, comprising permanent magnet three-phase synchronous motor, gear unit and frequency converter, achieves an efficiency up to 90%, yielding savings of up to 25% compared with conventional systems.
PM motor
With the VLT® OneGearDrive, Danfoss recommends PM motors to achieve optimum energy efficiency. With an efficiency of the drive of potentially up to 90% and high torque, the OneGearDrive already exceeds the highest IE3 super Premium Efficiency class defined in the new EU regulation.
Flexible plant design
The OneGearDrive lends itself equally well to central and decentral installations, giving the plant designer complete flexibility from the outset. Whether the inverter portion of the drive is to be housed immediately adjacent to the geared motor unit or must be housed in a central drive cabinet makes no difference to the performance at the drive shaft. Of course the normal rules governing cable length between inverter and gear motor unit.
High degrees of protection
IP67 and IP69K (OGD Hygienic) – allows unrestricted use in wash down areas
IP65 and IP67 (OGD Standard) – high protection in wash down areas
Hygienic design: EHEDG compliance/ IPA certified
The VLT® OneGearDrive Hygienic™ is the ideal choice for any application where hygiene is especially important. It complies with the requirements for best cleaning and hygienic design – with certification according to EHEDG (European Hygienic Engineering & Design Group). The drive units are also available with totally encapsulated resolvers.
The OneGearDrive Hygienic is resistant to cleaning detergents and disinfectants (pH 2..12).
IPA certified: The 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.
Complete smooth surface, Fan-free motor, No cooling fins
In both versions, completely smooth, easy to clean surface without cooling fins, prevents pockets of dirt from forming and allows cleansing agents to drain off freely. The fan-free motor avoids the risk of air-borne germs and dirt particles being drawn in and then expelled back into the surrounding air.
Long service intervals
The OneGearDrive runs 35,000 operating hours in partial operation between oil changes (by using food grade oil) – this means long service intervals, low maintenance cost and effort, and low operating cost.
Motor and resolver connection with CleanConnect® stainless steel connector (OGD Hygienic)
Allows safe connection in wet areas, fast replacement, and high cleanability. The proven stainless steel plug-and-socket connector simplifies replacement during maintenance.
This also allows the replacement to be performed by a mechanical service technician alone, without the assistance of an electrician.
Available hollow shaft
Diameters of 30, 35 and 40 mm allow flexible adaptation to customer standards. Available as stainless steel AISI 316Ti.
Awarded design
The design of the VLT® OneGearDrive Hygienic also opens up totally new aesthetic and key
stylistic elements in drive technology. The motor and gearbox together form a clean, simple
entity and the product won the red dot design award 2010 for “high product quality, expressing innovation in form and function in an exemplary manner”.
