High-end myoelectric prosthesis and coreless motor: precise control and future development
Leave a message
With the continuous advancement of biomedical engineering and artificial intelligence technology, high-end myoelectric prostheses are gradually changing the lifestyles of amputees. These intelligent prostheses can not only be precisely controlled through myoelectric signals, but also have greater flexibility and adaptability, allowing users to complete complex movements such as grasping, rotation, and fine adjustment.
However, to achieve these high-precision, high-response speed controls, the drive system inside the prosthesis is crucial. Different types of myoelectric prostheses have different performance requirements for motors. Among them, Coreless Motors have been widely used in high-end myoelectric prostheses due to their lightweight, high-speed response, and low energy consumption. Especially in parts that require tiny and fine control, such as fingers and wrists, Coreless Motors can provide smooth and precise power support , making prostheses closer to natural hand movements.
This article will delve into the core technologies of high-end myoelectric prostheses and analyze which types of myoelectric prostheses are most suitable for Coreless Motors. After that, we will introduce the working principle and advantages of Coreless Motors and recommend high-quality Coreless Motor manufacturers to help you better understand the application value of this key technology in the field of prostheses.
High-end myoelectric prosthesis: finger prosthesis and wrist prosthesis
High-end myoelectric prostheses are intelligent prosthetic devices that control the movements of prosthetic limbs by detecting electromyographic signals (EMG) generated by the muscles of the user's residual limbs. These prostheses are usually equipped with sensors, microcontrollers and high-performance motors, which can imitate the movement of natural limbs and achieve refined operations. Compared with traditional mechanical prostheses, myoelectric prostheses provide higher flexibility, precision and responsiveness, allowing users to complete more complex and natural movements.
High-end myoelectric prostheses can be divided into several types according to their functions and applicable scenarios, among which finger prostheses and wrist prostheses are one of the most common categories.
High-end myoelectric prosthesis: finger prosthesis
Finger prostheses are mainly used to help patients with amputated fingers or missing hands restore basic grasping, pinching and manipulation abilities, enabling them to perform daily tasks such as picking up objects, typing, using tools, etc.
Features:
Fine control: Highly sensitive motor drives are required to achieve flexible single-finger or multi-finger coordinated movements.
High response speed: Finger movements usually require quick responses, such as clenching, releasing, adjusting strength, etc.
Lightweight design: The prosthesis needs to be as light as possible to reduce the burden on the user's residual limb and improve wearing comfort.
High-end myoelectric prosthesis: wrist prosthesis
Wrist prostheses are used to help patients recover key movements such as rotation and bending, allowing them to smoothly complete daily operations such as twisting bottle caps, turning keys, and turning pages of books.
Features:
High flexibility: It is necessary to achieve multi-directional rotation (such as flexion and extension, internal and external rotation) to adapt to different application scenarios.
Smooth and precise: The motor is required to provide sufficient power while remaining smooth and stable and avoiding vibration.
Durability and low energy consumption: The wrist needs to work for a long time, so the motor needs to have a high energy efficiency ratio to reduce energy consumption and extend the life of the prosthesis .
Why are coreless motors particularly suitable for high-end myoelectric prostheses
Finger and wrist prostheses play an important role in the field of high-end myoelectric prostheses, and in order to achieve precise and stable movements, it is necessary to select the right drive motor. Among the many types of motors, the coreless motor is an ideal choice for finger and wrist prostheses due to its excellent performance.
The coreless motor is an ironless DC motor whose stator adopts a hollow cup winding design without the iron core in traditional motors, which gives it a series of unique advantages and makes it very suitable for high-end myoelectric prostheses.
Core Advantages of Coreless Motors
1. Lightweight, reducing the burden on prostheses
High-end myoelectric prostheses need to be as light as possible to reduce the burden on the wearer and improve comfort for long-term use. The coreless structure of the Coreless Motor makes it lighter than traditional brushed or brushless motors, which is very suitable for prosthetic applications such as fingers and wrists that require miniaturization and lightweight.
2. High-speed response and precise control
Finger and wrist prostheses require fast and precise movements, such as holding a glass easily, adjusting grip strength, turning a key, etc. The coreless motor has a very small rotor inertia and can respond quickly to control signals, achieving flexible and precise motion control, making the prosthesis more natural and smooth.
3. Low energy consumption, extending the life of prostheses
High-end myoelectric prostheses are usually powered by rechargeable batteries, so the energy consumption of the drive motor is critical. Since the coreless motor has no core loss, it has a higher energy efficiency ratio, reduces power consumption, and extends the battery life of the prosthesis, allowing users to use the prosthesis for longer without frequent charging.
4. Smooth operation and low noise experience
Compared with traditional brushed motors, coreless motors run more smoothly, avoiding the mechanical friction of brushed motors, reducing vibration and noise. This low noise feature is especially important for prosthetic users, which can bring a quieter and more natural user experience.
It is precisely because of these characteristics that the Coreless Motor has become an ideal driving solution for high-end myoelectric prostheses (especially finger and wrist prostheses). It not only provides a natural and precise movement experience, but also effectively improves the comfort and service life of the prosthesis, helping users to perform daily activities more freely.
