Design Focus: Frameless Means the Housing Is Yours

A frameless motor ships as stator, rotor and bearing bore only - no shell, no end caps. The customer's own housing becomes the motor housing, which removes a layer of radial thickness and a set of screws from the assembly. On a gimbal or pan-tilt head, that saved millimetres are usually what decides whether the axis fits behind the lens.

The outer rotor layout also changes the feel of the axis: inertia sits on the outside, so the load is carried by the rotor ring instead of the shaft, and the 12-slot stator spreads cogging across more positions per turn so the axis starts smoothly instead of stepping. With the drive board integrated, the customer supplies DC power and a PWM line.

Typical Applications

Camera gimbals, drone payload heads, robotic arms and end effectors, medical scanner heads, optical stabilisation platforms and compact rotary stages where the motor must disappear into the mechanical design.
