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. 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 and Machine 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 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 while also eliminating the need for leak-proof enclosures.

Open New Markets

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