Kollmorgen Direct Drive Frameless Motors
The KBM™ Series, from Kollmorgen, 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 motor that provides the highest performance in the most compact space.The KBM™ series offers high performance, long life and simple installation in a motor kit that can be embedded directly in your machine design.
Benefits of Frameless Motors include:
Direct load connection eliminates maintenance of gearboxes, belts or pulleys
Zero backlash and compliance provides more responsive system performance
The TBM frameless motor is a new series of direct drive torque motors designed for applications that require high power in a small compact form factor with minimized weight, and inertia. Typical applications include robotic joints, weapon stations, sensor gimbals, sight systems, UAV propulsion and guidance, as well as many others. Features include:
3 frame sizes ranging from 60mm (2.36 inches) up to 129mm (5.08 inches)
3 stacks lengths per frame
2 standard winding options per frame
Latching Hall Effects (pre-aligned / factory installed).
Low Cogging designs
Stainless Steel Yokes for max corrosion protection
Laser Marked Armatures
SLMTI Torque Systems Direct Drive Frameless Motors
MDM-5000 Direct Drive Sets (Frameless Motors Kit Versions), from SLMTI Torque Systems, have been developed to fit applications where size and weight are important factors. Direct Drive technology allows for high servo stiffness which maximizes rate and position accuracy because there are no belts, gears or backlash inherent with most other servo systems. MDM-5000 Direct Drive Sets are supplied as two pieces; a cut-core segmented stator and a rotor. The stator is molded in a thin walled aluminum housing using thermally conductive epoxy, which provides excellent heat transfer and protects the windings (and optional integrated Hall board) from damage during installation and handling. The rotor is coated with a polymer shrink wrap which protects the magnets from dislodging during operation and also prevents damage while handling.
Brushless design provides high performance with zero maintenance
High efficiency, excellent heat transfer, high torque density
Rotor coated with polymer shrink wrap which protects magnets from dislodging during operation and prevents accidental damage while handling
High pole count, low cogging, smooth operation
High torque to inertia ratio ideal for high acceleration/deceleration mode with rapid start-stop
