Direct Drive Frameless Rotary Motors
The LiveDrive® LDX is a patented frameless motor with superior torque to length, torque to mass, and motor constant (Km) compared to other direct drive motors. Your machines can accelerate faster, with increased payload, and reduced size/weight.
Welcome to the next generation of direct drive rotary motors – where more performance comes in smaller packages to unlock breakthrough applications.
The LiveDrive
Advantage
- Design flexibility, windings, diameters and stack lengths
- Versatile integration: bond, clamp, threaded hub, through hole
- Superior dynamic performance with direct torque transmission
- Compact motor architecture
- Compatible with most industry-standard servo drives
High Performance
LiveDrive LDX frameless motors provide superior torque to length, torque to mass, and motor constant (Km), so you can move higher payloads faster.
Simplify: Less is More
Commission a system quickly by managing fewer parts in the supply chain. Our compact motor architecture has no drive subassemblies, such as gears and belts to maintain. Fewer parts means decreased failure points.
More Compact Machines
With compact motor architecture, the LDX allows you more design flexibility (windings, diameters and stack lengths). Less weight and floor space helps you drive more value from your machinery.
Versatile Integration
Bond, clamp, threaded hub or through hole; LDX provides flexibility in overall design and cable management. Industry standard voltages and currents as well as custom windings for any system or application.
