KBM™ Series Frameless

The KBM™ Series is designed to be directly embedded in your machine using the machine’s own bearings to support the rotor. With a huge selection of standard motors—plus our ability to quickly and cost-effectively incorporate co-engineered modifications—you can choose an exact-fit frameless motor that provides the highest performance in the most compact space.

Differentiate Your Machine

Embed the motor seamlessly into your machine design, optimizing the footprint and performance of your machine for enhanced quality and increased throughput.

3D Cutting Success Story

Increase Uptime

Reduce the complexity of your machine's design. Directly driving your load by removing failure prone transmissions will decrease the likelihood of costly failures and reduce the need for expensive, preventive maintenance. The end result is a reduced total cost of ownership in your machine.
