Inside the fingertips of humanoid robots, the joints of surgical manipulators, and the propeller drive modules of drones, there is a tiny motor with remarkable power density that is quietly driving the evolution of future technology. This motor is known as the “jewel in the crown” of the electric motor industry – the coreless motor.
Industry Trend: The Core Power Behind the Precision Drive Era
With the rapid development of intelligent robots, medical devices, and high-end equipment, the market demands ever more stringent performance from micro-drive systems: not only must they deliver ample power within extreme size constraints, but they must also achieve millisecond-level precision response and ultra-long, stable operation.
Thanks to its unique ironless rotor structure, the coreless motor breaks through the technical limitations of conventional motors caused by hysteresis losses and eddy current losses. By adopting a hollow cup (coreless) winding design, the motor achieves an impressive mechanical time constant – some high-performance products can reach less than 10 milliseconds, offering dynamic response capabilities far superior to traditional brushed motors. At the same time, the absence of cogging torque provides exceptional smoothness in precision instruments. These technical advantages make the coreless motor the inevitable choice for cutting-edge applications such as robotic dexterous hands, high-precision medical equipment, and satellite attitude control systems.
From a market perspective, this sector is entering a long-term growth trajectory. According to QYResearch, the global coreless motor market size is expected to reach USD 3.379 billion by 2032, with a steady compound annual growth rate of 5.5%. Notably, the humanoid robot segment is experiencing explosive growth – the global humanoid robot coreless motor market is projected to achieve an astonishing CAGR of 78.9% from 2026 to 2032. At the same time, the wave of domestic replacement (localization) is bringing unprecedented strategic opportunities for local manufacturers.
Technological Breakthrough: Giving Chinese Manufacturing a “Precision Heart”
For a long time, international brands such as Switzerland’s MAXON and Germany’s FAULHABER have dominated the high-end coreless motor market thanks to their deep technical expertise. However, this landscape is gradually being reshaped by a group of domestic companies committed to technological innovation.
Located in the heart of the Guangdong-Hong Kong-Macao Greater Bay Area manufacturing hub, Dongguan Sinbad Motor Co., Ltd. (Sinbad Motor) has been firmly focused on high-end coreless motors since its founding in 2011. The company’s main products cover brushed and brushless series with diameters ranging from 10mm to 50mm, backed by a standardized and comprehensive quality management system. Through more than ten years of relentless process development and production line upgrades, Sinbad’s independently developed coreless motors offer outstanding advantages: high energy conversion efficiency, strong operational stability, low noise, light weight, and long life. They are widely used in robotics, medical devices, information and communication, power tools, model aircraft, beauty instruments, and many other high-tech fields. With its deep technical accumulation, Sinbad has been granted 6 utility model patents and continues to close the gap with first-tier international brands through ongoing refinement.
Notably, Sinbad’s high-performance coreless motors have achieved performance comparable to international brands such as MAXON and FAULHABER in several key parameters, offering a cost-effective domestic alternative. This breakthrough not only significantly reduces procurement costs for downstream customers but also effectively removes the long-standing supply chain bottleneck that relied heavily on imported high-end micro motors, providing a solid foundation for the autonomy and control of Chinese-made equipment.
Benchmark Product: Redefining Value Leadership with Hardcore Specifications
Among the top 10 potential Chinese coreless motor companies in 2025, many local players have shown their strengths in various niche segments. Sinbad continues to compete steadily through continuous iteration and innovation, with its XBD-3260 model coreless DC motor epitomizing the company’s technical expertise and manufacturing excellence.
This motor features a 32mm square flange mounting structure, making it an efficient drive solution for compact equipment. Under rated operating conditions, it delivers 100W output power and 6,000 RPM high-speed operation while maintaining an energy conversion efficiency of over 85%. Thanks to the advanced coreless winding design, the motor exhibits exceptionally fast dynamic response during startup, acceleration, and frequent reversal, while effectively suppressing torque ripple and electromagnetic noise at low speeds, ensuring ultimate smoothness in high-precision closed-loop control. With a design life exceeding 5,000 hours, it is perfectly suited for demanding applications such as medical diagnostic instruments, laboratory automation equipment, small robotic joints, and high-end power tools.
Moreover, Sinbad offers flexible customization services based on customers’ specific power, size, and mounting requirements, providing highly matched micro-precision drive solutions for various industries.
More Than Just Products: Driving Win-Win Cooperation with “Manufacturing + Service”
In the high-end manufacturing sector, excellent hardware specifications must be complemented by systematic service capabilities and comprehensive delivery support. To that end, Sinbad has built a strong barrier through its interdisciplinary R&D team in product structure design and process optimization.
From initial feasibility assessment and sample making to mass production and full lifecycle technical support, Sinbad has established a rigorous and well-coordinated customer service system. In recent years, the company has successfully served dozens of industry customers from South Korea and various regions of China, delivering tens of thousands of custom coreless motor solutions. Its clients include well-known companies such as TS TECH, and its products have been exported to Europe, America, Southeast Asia, and other regions. Sinbad operates a modern R&D, production, and office campus equipped with multiple high-end intelligent automated production lines, ensuring efficient and stable mass production. Looking ahead, Sinbad will continue to pursue its long-term vision of “becoming a leading player in China’s motor industry,” driving efforts in industry standard-setting and technology leadership while expanding from motor components to integrated precision transmission solutions.
