No Gearbox. No Downtime. No Contamination.
Bring maximum speed, accuracy, and productivity to your robotics with LiveDrive® LDD - our patented direct drive motor that eliminates the need for servo gearheads while simplifying robot architecture.
LiveDrive for Robotics
Welcome to the next generation of robotics. LiveDrive LDD is a unique direct drive motor that overcomes almost every limitation of servo geared solutions.
Trusted by Innovative Robot and Machine Builders Across Europe and Beyond.
Zero Maintenance & Zero Downtime
With no need for gears, belts, or lubrication, LiveDrive motors dramatically simplify the drivetrain, reducing the need for scheduled or unscheduled maintenance and improving overall MTBF.
Zero Contamination Risk. Full compliance.
Protect hygiene-first products from the risk of oil leaks and contamination without the need for additional sealing or casing. Follow EHEDG, USDA/FDA, and CFIA guidelines more easily.
IP67 Ingress Protection
LiveDrive is 100% protected from ingress of moisture and dust, allowing fast and easy light washdown cleaning of your machines.
Unmatched Accuracy & Speed
Improve accuracy, rigidity, repeatability, acceleration and stopping time by fully eliminating backlash and lowering the inertia inherent in any geared drivetrain.
Improve Robot Density
With a compact footprint, LiveDrive allows you to implement more flexible systems with less floor space to drive more value from your machinery.
Faster Robot Assembly
Commission your robots more quickly by managing fewer components in the supply chain, and reduce the tuning efforts needed to resolve backlash compensation.
Reduce Robot Build Costs
With fewer components needed to build or to store as spares, LiveDrive requires less paid labor for assembly while also eliminating the need for leak-proof enclosures.
Open New Markets
Use robots empowered by LiveDrive as a feasible replacement to other more expensive, less flexible robotic solutions.
