LDD LiveDrive in action with a Delta Robot

Direct Drive Housed Rotary Motors

No Gearbox. No Downtime. No Contamination.
Bring performance accuracy and reliability, lower total cost of ownership to your robotics and machines with LiveDrive® LDD – our patented direct drive motor eliminates the need for servo gearheads while simplifying robot and machine architecture.

Welcome to the next generation of robotics and machinery. LiveDrive LDD is a unique direct drive motor that overcomes performance limitations of backlash, accuracy, and repeatability, found in all geared servo motors.

The LiveDrive
Advantage

Zero Maintenance. Zero Downtime.

With no need for gears, belts, or lubrication, LiveDrive motors dramatically simplify your 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. LiveDrive makes it easier to adhere to the EHEDG, USDA/FDA, and CFIA guidelines.

IP67 Ingress Protection

LiveDrive is 100% protected from ingress of moisture and dust, allowing fast and easy light washdown cleaning of your machines.

Dynamic Performance

Improve accuracy, rigidity, repeatability, acceleration, and stopping time by fully eliminating backlash and lowering the inertia inherent in any geared drivetrain.

Improve Robot and Machine Density

Optimize space and drive more value from your machinery. With up to 50% reduction in drivetrain length, LiveDrive allows you to implement more flexible systems using less floor space.

Faster Robot and Machine Assembly

Commission your robots and machinery more quickly by managing fewer components in the supply chain and reduce the tuning efforts needed to resolve backlash compensation.

Reduce Robot and Machine Build Costs

With fewer components needed to build or to store as spares. LiveDrive requires less paid labor for assembly and eliminates the need for leak-proof enclosures.

Open New Markets

Use robots and machines powered by LiveDrive as a feasible replacement to more expensive, less flexible robotic and machinery solutions.
