Ⅳ.Types of Motors for Humanoid Robots

1.Brushless DC (BLDC)Motor 

BLDC motors offer advantages such as high efficiency, low energy consumption, low noise, ultra-long lifespan, and high reliability. Furthermore, they exhibit good linearity in mechanical and adjustment characteristics, a wide speed range, and are easy to maintain.

In humanoid robots, BLDC motors are commonly used to drive joints, arms, legs, and other parts requiring precise control and high-efficiency energy conversion.

2. Permanent Magnet Synchronous Motor (PMSM)

PMSM motors use permanent magnets for excitation. They have a simple structure, require no excitation current or excitation losses, and therefore have high efficiency and power density. They operate stably and have a fast response speed, making them suitable for applications requiring high precision and high dynamic performance.

In humanoid robots, PMSM motors are commonly used in applications requiring precise position control and high-speed response, such as head rotation and hand grasping.

3. Servo Motors

Servo motors offer even higher control precision and response speed. They employ closed-loop or semi-closed-loop control methods, equipped with encoders and feedback mechanisms to ensure high control precision and smooth speed response. Servo motors are widely used in applications requiring precision control, such as semiconductors, photovoltaics, lithium batteries, and industrial robots. In humanoid robots, servo motors are one of the core control components, used to achieve high-precision movements and complex control.

4. Stepper Motors

Stepper motors have a simple structure and low cost, but their efficiency and control precision are relatively low. Stepper motors directly convert pulse signals into angular momentum, with a constant step angle. They are typically used in open-loop control systems, such as office automation, communication equipment, and printing equipment. In humanoid robots, stepper motors may be used in auxiliary parts where high control precision is not required.

5. Frameless Torque Motors

Frameless torque motors are multi-stage, housing-less direct-drive motors that offer enhanced torque and a compact structure. Their specifications and selection depend primarily on torque, not power. These motors can continue to operate and provide stable torque to the load even at low speeds or when stalled, and the load is directly connected to the rotor, reducing frictional losses. Frameless torque motors are mainly used in collaborative robots and other fields. Due to their compact size, high torque, and hollow wiring characteristics, they are also suitable for use in the joint design of humanoid robots.
