Highest Industry Torque

LiveDrive LDX frameless motors provide superior torque with design flexibility. With the industry-highest torque, you can move higher payloads faster.

Simplified Design

Commission a system quickly by managing fewer parts in the supply chain. A simpler design without drive sub assemblies, such as gears and belts to maintain.

Smaller Form Factor

With a compact footprint, the LDX frameless allows you more design flexibility with less weight and floor space to drive more value from your machinery.

Easier Integration

Large through-bore shaft provides flexibility in overall design and cable management. Standard and custom windings for any system voltage or application.
