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
- Compact: our motor is 50% smaller than typical geared drivetrains
- Performance accuracy and reliability, lower the total cost of ownership
- Options for IP67, brake, bearings, connectors and encoders
- Compatible with most industry-standard servo drives
Trusted by Innovative Robot and Machine Builders Worldwide.
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.
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.
