The rotor, typically the internal component, comprises a rotating steel ring assembly with permanent magnets that mounts directly onto the machine shaft, while the stator serves as the external component with steel laminations and copper windings wrapped around the gear exterior to generate electromagnetic forces that tightly adhere within the machine housing. The global Frameless Motor market is estimated to be valued between 1.8-3.6 billion USD in 2025, representing a dynamic and strategically important segment within the precision motion control sector. The market is projected to experience robust compound annual growth rates ranging from 8.5% to 16.5% through 2030, driven by expanding applications in robotics and industrial automation, humanoid robot development, aerospace systems, and the growing demand for compact, high-performance motion solutions in advanced manufacturing and specialized applications. The frameless motor configuration offers unique advantages including maximum power density, minimal installation envelope, enhanced design flexibility, and direct integration capability that traditional enclosed motors cannot match. This technology enables engineers to create more compact, efficient, and powerful motion systems while reducing overall system complexity and maintenance requirements.
