KBM Series Frameless

KBM™ Series Frameless Motors

The KBM™ Series provides low- and high-voltage motors (120–480 Vac) 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 modify leads, windings, stack lengths and more—you can choose an exact-fit frameless motor that provides simple installation, long life and the highest performance in the most compact space.
