Coreless Motor Solution for Dexterous Hand

Preface

Driven by the rapid commercialization of embodied AI and humanoid robots, precise end-effector operation has become a key competitive advantage in the robotics industry. Micro coreless motors, precision brushless coreless motors and small brushed coreless motors act as the core driving unit of robotic dexterous hands, directly determining grasping accuracy, clamping force, response sensitivity and load capacity.

The booming market of bionic dexterous hands and multi-DoF flexible manipulators has surged global demand for small-size high-torque coreless motors, low-noise micro precision motors and long-life micro drive motors. These compact, high-performance motors have become standard components for humanoid robots, medical devices and industrial automation equipment.

1. Industry Background & Market Status

Global industrial flexible transformation, intelligent service robot popularization and medical bionic technology iteration fuel the rapid growth of the humanoid dexterous hand industry.

Traditional iron-core motor-driven grippers suffer from bulky structure, insufficient torque, low precision and slow response, failing to meet high-precision flexible operation needs.

In contrast, dexterous hands equipped with micro coreless drive motors, high-speed precision coreless motors and high-torque micro motors effectively solve industrial pain points and replace conventional manipulators in high-end scenarios. Industry statistics show dexterous hand sales achieved 19,200 units in 2025 (230% YoY growth), with sales expected to exceed 70,000 units in 2026. The expanding downstream market continuously boosts demand for low-inertia coreless motors, micro precision drive motors and small-size torque motors, accelerating domestic high-end micro motor substitution.

2. Key Application Scenarios & Motor Matching

Dexterous hands serve as critical robotic end-effectors for refined interactive and operational tasks. Different industrial scenarios require matched coreless motor models, micro motor specifications and precision drive solutions to ensure stable and accurate bionic movement.

2.1 Humanoid Robots

Service and industrial humanoid robots demand ultra-precise bionic movement, requiring ultra-thin coreless motors, high-torque micro brushless motors and low-noise robot motors. These motors support delicate tasks including object grasping, tool manipulation and human-robot interaction.

2.2 Industrial Automation

3C assembly, precision component sorting and auto part testing require durable, high-precision power units. High-speed coreless motors, high-precision brushed coreless motors and fatigue-resistant micro drive motors enable long-cycle, high-repeatability industrial production.

2.3 Medical Rehabilitation Equipment

Surgical robots, bionic prosthetics and rehabilitation devices adopt medical-grade brushless coreless precision motors, low-vibration micro motors and high-stability miniature motors, delivering high precision, low interference and long service life for safe medical operations.

2.4 Special & Smart Service Operations

Aerospace maintenance, nuclear environment operation and disaster rescue require highly reliable power systems. High-power coreless motors, high-load micro drive motors and customized precision motors adapt to harsh working conditions and ensure stable long-term operation.

3. Coreless Motor Types & Competitive Advantages

Coreless DC motors are the optimal power solution for dexterous hands, featuring zero iron-core loss, low inertia, lightweight design and high power density — outperforming traditional iron-core motors in precision, response speed and load performance. The industry mainly classifies coreless motors into brushed and brushless types for differentiated scenario adaptation.

3.1 Brushed Coreless Motors

Brushed micro coreless motors feature simple structure, fast start-stop response, high precision and cost-effectiveness. With easy debugging and stable low-speed output, they are ideal for light-load scenarios including civilian service robots and small-medium dexterous hands.

3.2 Brushless Coreless Motors

Brushless precision coreless motors eliminate carbon brush wear, featuring longer lifespan, lower noise, higher torque and wider speed regulation. Supporting 24-hour continuous operation, these overload-resistant motors are widely used in high-end equipment such as medical surgical robots and industrial high-precision dexterous hands.

4. Motor Selection Standards for Humanoid Dexterous Hands

High-performance humanoid dexterous hands require motors that support compact size, exquisite integration, strong gripping force and high load capacity. Qualified coreless motors must feature miniaturized dimension, high torque density, large clamping torque, low inertia and lightweight structure to balance small volume and powerful output.

Precision coreless motors effectively solve traditional micro motor defects including insufficient power, precision deviation and short service life. They enhance dexterous hand grasping stability, operational accuracy and overall load limit, becoming the exclusive driving solution for premium bionic manipulators.
