Giving machines a sense of touch: the coreless motor – the powerful "heart" of the dexterous hand era.

2026 – In the wave of humanoid robots moving from laboratories to homes, if artificial intelligence is the brain, then dexterous hands are the "last centimeter" for robots to perceive the world and interact with everything. The secret weapon driving these "hands" to achieve human-like delicate operations is that tiny yet powerful heart – the coreless motor.

With the mass production of flagship products like the Tesla Optimus Gen3 and the strong rise of the domestic supply chain, 2026 has become a crucial year for the explosive growth and commercialization of dexterous hand technology. Today, we take you to the heart of this micro-drive revolution and witness how the coreless motor redefines the "fingertip power" of machines.

Why must dexterous hands be "hollow"?

In traditional understanding, motors often mean bulkiness and vibration. But in a dexterous hand with a diameter of less than 10 millimeters and needing to accommodate more than 20 degrees of freedom, every micrometer of space is precious.

The Coreless Motor, with its unique coreless rotor design, completely breaks through the physical limitations of traditional motors: Zero cogging effect, extremely smooth operation: Eliminating magnetic resistance fluctuations caused by the iron core, torque ripple is as low as 0.1%. This means that when a robot's finger picks up an egg or threads a needle, the movement is silky smooth, without any jerking.

Ultra-high power density: Output power is increased by more than 30% in the same volume. A tiny body contains enormous energy, allowing a dexterous hand to gently grasp grapes and steadily lift heavy objects.

Millisecond-level response: Extremely low rotational inertia, instantaneous start and stop. Combined with advanced control algorithms, the robot can detect object slippage in real time and adjust the gripping force, achieving true "tactile feedback."

Long lifespan and low noise: The brushless design, combined with precision bearings, achieves a lifespan exceeding 10,000 hours and operates quietly, perfectly suited for noise-sensitive scenarios such as medical care and home services.

From the "Swiss Club" to "Made in China": A Miracle of 67% Cost Reduction Once upon a time, the high-end coreless motor market was monopolized by European giants such as Maxon of Switzerland and Faulhaber of Germany, with a single motor costing as much as 4,500 yuan, becoming a major obstacle to the mass production of humanoid robots.

However, in 2026, the landscape has changed. Chinese manufacturers, represented by Mingzhi Electric, Topband, and Kegu Motor, have successfully reduced the unit price of coreless motors to around 1,500 yuan through technological breakthroughs and large-scale production, resulting in a significant cost reduction of 67%. This breakthrough not only broke the overseas monopoly but also brought the overall cost of humanoid robots to the point of commercialization.

According to industry data, the global dexterous hand market reached 6.3 billion yuan in 2025, while the Chinese market reached 50.1 billion yuan, with a compound annual growth rate exceeding 300%. It is projected that by 2035, the dexterous hand motor market alone will exceed 170 billion yuan. Domestically produced coreless motors, with their high cost-effectiveness and rapid customization capabilities, are becoming the preferred choice in the global robot supply chain.

Application Scenarios: Beyond Robots

While humanoid robots are the most prominent stage for cored motors, their applications have already expanded infinitely:

Healthcare: In portable diagnostic devices and minimally invasive surgical robots, their quiet operation and high precision ensure patient safety and comfort.

Aerospace: Used in satellite solar panel deployment mechanisms and drone gimbal control, maintaining superior performance in extreme environments.

Smart Wearables: Empowering exoskeleton gloves and smart prostheses, helping people with disabilities regain their ability to live independently, bringing warmth to technology.

Precision Manufacturing: Achieving yield and efficiency surpassing manual labor in 3C electronics assembly and micro-parts sorting lines.
