Robotics Motor Core

We provide a variety of robot motor cores for robot key components, utilizing self-bonding technology to deliver more efficient, stable, and quiet solutions.

Background

The robotics industry has developed rapidly in recent years, especially in the fields of industrial robots, service robots, and humanoid robots, showing significant technological breakthroughs and market expansion trends.

And with the leap of artificial intelligence (AI) technology, the application scenarios and demands of robots in various fields are gradually expanding, and the industry is moving towards a new stage of popularization and intelligence.

Coreless motors play a crucial role in the field of robotics, especially in the application of humanoid robots dexterous hands, are the core actuators for the dexterous hands of humanoid robots.

Coreless Motor

Coreless features a unique ironless rotor design that eliminates iron loss and reduces weight, resulting in high power density, high torque density, and fast response speed. The rotor in a coreless motor is a hollow, cup-shaped structure with windings and magnets inside.
 
Coreless motors have a high peak torque because the torque constant remains unchanged as the current rises to its peak, allowing the motor to generate a larger peak torque. Conversely, conventional iron core DC motors reach saturation, and increasing current does not increase torque.
 
Humanoid robots are a key application area for coreless motors, particularly in dexterous hands where they drive finger movement. The rotation of the coreless motor drives a planetary reducer to apply a reverse force, pulling the finger joints through hinges and other connections, converting rotational motion into linear motion. Applying positive or negative voltage allows the fingers to extend and retract, enabling grasping and releasing objects.
