Global Robot Hollow Cup Motors Market Strategic Research Report

Scope of the Report

The global Robot Hollow Cup Motors market size is predicted to grow from US$ 72.19 million in 2025 to US$ 4,465 million in 2032; it is expected to grow at a CAGR of 81.8% from 2026 to 2032.

The hollow cup motor is a DC permanent magnet servo control motor. Structurally, it breaks through the traditional stator and rotor structure of motors and adopts a coreless stator/rotor, which fundamentally solves the inherent problems of the core structure. Compared to traditional cored motors, coreless motors offer numerous advantages, such as high motor speed, extremely high energy conversion efficiency, high acceleration, high dynamic response, small size, and light weight. Coreless motors are divided into two types: brushed coreless and brushless coggingless. Brushed coreless motors have a coreless rotor, while brushless coreless motors have a coreless stator. The two types differ in their final product performance characteristics and applications. The production technology of coreless motor coils mainly involves winding production and one-time forming production. The winding production method is complex, requiring copper wire to be wound into a hollow coil of a certain geometric shape, then flattened into a flat copper wire sheet, and finally wound into a cylindrical coil. Winding efficiency is relatively low in production methods, and one-step molding is currently the mainstream approach. The aforementioned straight-winding, oblique-winding, and concentric windings are all used in automated one-step molding equipment, but Chinese companies primarily use winding production. Motors are a key component of humanoid robots. The joints of humanoid robots require both high degrees of freedom and high-precision control. In applications where space is limited, such as finger joints, the advantages of coreless motors—small size, high power density, high response speed, and high-precision control—become prominent. The large-scale development of the global humanoid robot industry is expected to drive broad prospects for the application of coreless motors. In 2024, global production of Robot Hollow Cup Motors reached 763,600 units, with an average selling price of $89.57 per unit. With a gross profit margin of approximately 35%-40%, the company produces 8.6 million high-efficiency motors annually. The upstream raw materials for coreless motors include copper, steel, magnets, bearings, and plastics. The upstream winding equipment industry is mainly concentrated in Europe, America, and Japan, with companies including Meteor (Switzerland), Tanaka Seiki (Japan), and Nippon Machinery (Japan). Coreless motors were initially used in cutting-edge industries such as aviation, aerospace, and the military. In recent years, their applications have gradually expanded to civilian sectors, such as medical devices, consumer electronics, power tools, and industrial automation. Case studies: Coreless motors are already used in surgical robots in the medical industry, and Tesla's Optimus robot's hand motion control solution also employs a coreless motor + worm gear + tendon cable drive transmission control.

Compared to traditional DC motors, coreless motors first and foremost possess energy-saving characteristics. Due to their coreless design, they completely eliminate energy losses caused by eddy currents formed by the iron core, resulting in very high energy conversion efficiency. Their maximum efficiency is generally above 70%, and some products can reach over 90% (compared to around 70% for iron-core motors). They also possess excellent control characteristics, with rapid starting and braking, extremely fast response, and a mechanical time constant of less than 28 milliseconds, with some products achieving less than 10 milliseconds (compared to over 100 milliseconds for iron-core motors). Furthermore, they allow for convenient and sensitive speed adjustment during high-speed operation within the recommended operating range. In addition, it boasts excellent drag characteristics, meaning highly reliable operation with minimal speed fluctuations; as a micro-motor, its speed fluctuations can be easily controlled within 2%. It also exhibits lightweight characteristics, reducing weight and volume by 1/3 to 1/2 compared to iron-core motors of the same power, while significantly increasing energy density.

The global coreless motor market is dominated by overseas companies, resulting in high market concentration. Coreless motors are technologically advanced and difficult to manufacture. Furthermore, the expanding downstream applications and varying performance requirements necessitate customized production capabilities from manufacturers. Moreover, rapid technological updates require coreless motor manufacturers to iterate and optimize their products promptly. Currently, the global coreless motor market remains dominated by overseas manufacturers, with foreign manufacturers expected to hold over 80% market share in 2024. The downstream applications of coreless motors are expanding rapidly, continuously increasing market potential. On one hand, the increasing demands for precision and speed in medical devices and aerospace industrial automation products are driving the continued expansion of the coreless motor market. On the other hand, the fast response and high precision of coreless motors are well-suited for humanoid robot hand joints; with the mass production of humanoid robots, coreless motors are expected to see a new market, further increasing the upper limit of the market size.
