What is a Frameless Servo Motor?

A frameless servo motor consists of a stator and a rotor and is supplied without a housing, bearings, or a shaft. A conventional servo motor typically uses a cylindrical or rectangular housing to secure and protect its internal components.
Frameless servo motors are designed to fit directly into the customer's machine. The machine itself serves as the motor housing, which can significantly reduce the overall size and weight of the assembly. Directly driving the load eliminates backlash from couplings or belts and improves response. KOMOTEK's frameless motors feature a hollow bore for routing cables.
These features make frameless motors well suited for robotic arm joints, satellite antenna drives, and drone gimbals.
