LDX Frameless Models

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.

* Assumes a 100°C temperature rise from 20°C ambient to the maximum winding temperature.

** Motors can be operated at different voltages. Contact an Applications Engineer for inquiries with special voltage requirements.

*** Increasing the ambient temperature derates motor performance.
All electrical and performance specifications have ±15% tolerance. Specifications are preliminary and subject to change.
