Frameless motors consist of a wound stator and a separate permanent-magnet rotor. They do not include the additional components that are part of a traditional housed servo motor — the motor housing, endbells. bearings, output shaft, cable connectors, feedback device or brake.
By eliminating the need to design your application to accommodate the extra components of a traditional housed servo motor, frameless motors enable you to engineer the most compact and lightest possible motion application.
Kollmorgen frameless motors provide industry-leading torque density, precision and efficiency in the most compact package. Our frameless motors are ideal for rotary actuators, submersible propulsion systems, flight control surface actuators, sensor gimbals, robot and cobot joints, or any application that requires ultimate precision, power and reliability in a compact application design.
When you can’t find the ideal-fit housed motor, frameless is your best choice. Learn more about what is a frameless motor in our Technologies Explained series.
Incorporating Frameless Motors Into an Environmentally Resilient Design
Daily washdowns, deep-sea submersion, high radiation, high vacuum, hazardous atmospheres: When a housed servo motor can’t provide the protection you need in a compact form factor, consider embedding a frameless servo motor. Read this white paper to learn how.
Achieving Ultimate Motion Precision Using Frameless Servo Motors
Frameless motors aren’t just for robotic joints. Compact actuators, sensor system gimbals, submersible propulsion systems and other applications benefit from direct drive precision and compact design. Learn how to directly embed a frameless motor in your mechanism.
