Coreless Motors: Revolutionizing Industrial Automation with High Efficiency and Precision

In recent years, with the rapid transformation of manufacturing industry towards intelligence and automation, industrial automation equipment is becoming more and more advanced. This has also led to increasing requirements for production efficiency, precision, energy saving and equipment stability, which has directly promoted the development of new drive technologies. In the past, traditional motor systems were widely used in the industrial field, but with the development, traditional motors have gradually exposed their limitations such as large inertia, slow response and high energy consumption in some high-precision, high-response and low-energy consumption scenarios. At this time, the Coreless Motor, as a high-efficiency, low-inertia and high-response motor solution, is emerging in the field of industrial automation.

 

 

The coreless motor is a special DC motor ( including brushed and brushless series ) with a cup-shaped structure and a coreless winding for the stator coil. Since there is no core stator like the traditional motor, the coreless motor has the characteristics of low inertia, high efficiency, fast response, low energy consumption and low noise, and is widely used in the field of high-precision control and automation equipment.

 

So why are Coreless Motors gaining more and more attention in recent years? There are two main reasons:

The first is the rapid development of coreless motor technology. With the improvement of manufacturing technology, the winding process, magnetic materials and control technology of coreless motors have made significant breakthroughs, making their performance more superior and their application scenarios more extensive. For example, the optimization of high-precision winding technology makes the motor's energy conversion efficiency higher and the loss lower.

 

Second, the development of intelligent robots has made more people discover the advantages of Coreless Motors. Intelligent robots have very stringent requirements on drive motors, requiring high dynamic response, low inertia, and high efficiency motor solutions, and traditional motors are difficult to meet these requirements. Coreless Motors have become an ideal choice for intelligent robots and automation equipment due to their low inertia, high acceleration capability, and precise control.

 

 

In industrial automation equipment, the performance of the drive system directly affects the overall production efficiency and precision. The coreless motor, with its unique ironless structure and high dynamic response characteristics, significantly optimizes the operation of industrial automation equipment, mainly in the following aspects:

 

High power density and lightweight design

The coreless motor uses an ironless rotor structure, which is lighter and has a higher power density than traditional motors. It can provide greater output power at the same volume and weight, which makes it particularly good in weight- and space-sensitive application scenarios, such as precision automation equipment, drones, and portable medical devices.

 

High efficiency and low energy consumption

Due to the ironless structure, the coreless motor avoids the energy loss caused by the iron core eddy current loss and hysteresis loss of the traditional motor. In addition, its brushless drive mode optimizes the current commutation through electronic control and reduces the friction loss caused by the carbon brush and commutator, thereby further improving the operating efficiency and making the equipment more energy-efficient in long-term operation.

 

Fast response and precise control

The low inertia design of the coreless motor enables it to respond quickly to current and voltage changes, achieving high-precision start-stop and speed control. Especially in the field of industrial automation that requires fast response and precise operation, such as robot joints, intelligent gripping systems, etc., the coreless motor can ensure that the equipment executes instructions with extremely high sensitivity and improves overall production accuracy.

 

Low noise and low vibration

Since the coreless motor has a more uniform magnetic field distribution, it does not produce significant magnetic resistance torque fluctuations during operation, which effectively reduces noise and vibration. This makes it a better drive choice in application scenarios that have strict requirements on quietness and stability, such as high-precision manufacturing equipment and medical instruments.

 

Long life and low maintenance cost

The brushless structure of the coreless motor reduces mechanical friction during operation, reduces the possibility of wear and damage, and thus extends the service life of the motor. In addition, due to its simple structure, the maintenance workload is greatly reduced, which not only reduces equipment downtime, but also effectively reduces maintenance costs.

 

Through the above introduction, we can clearly understand that the Coreless Motor has shown strong competitiveness in the field of industrial automation with its many advantages such as high power density, high energy efficiency, fast response, low noise and low vibration, and long life. With the intelligent upgrading of the manufacturing industry, the application scenarios of Coreless Motors will continue to expand and play a more important role in the development of industrial automation equipment in the future.

 

 

This requires a comparison between coreless motors and traditional motors. Like the brushless motor series, coreless motors have many technical advantages. These features not only make them stand out in the field of industrial automation, but also make them perform better in application scenarios such as high precision, low energy consumption, and fast response.

 

1. Lighter and smaller, with higher power density

Traditional motors usually use an iron core stator structure, which makes the motor larger and heavier, increasing the overall burden of the equipment. The Coreless Motor uses an ironless winding structure, which greatly reduces the weight of the motor and improves the power density. Under the same volume, the Coreless Motor can provide higher power output, which is particularly suitable for equipment with strict requirements on lightweight and high performance, such as portable automation equipment, intelligent robots, drones, etc.

 

2. Low inertia design to achieve ultra-fast dynamic response

The iron core structure of traditional motors results in a large rotor inertia, which affects the acceleration and braking performance of the motor. However, due to its ironless design, the coreless motor has an extremely low moment of inertia and can reach the target speed or stop running in a very short time. This feature gives it an obvious advantage in scenarios that require fast start and stop and high responsiveness, such as industrial robot joints, high-speed precision transmission equipment, medical surgical robots, etc.

 

3. Higher energy efficiency and reduced electromagnetic loss

The iron core structure of traditional motors is prone to eddy current loss and hysteresis loss, which reduces the overall energy efficiency. The coreless motor adopts a coreless design, which avoids hysteresis loss and eddy current effect in the core, greatly improving the electromagnetic conversion efficiency. Combined with high-precision winding technology, the coreless motor can provide higher output power at lower energy consumption, and is suitable for precision instruments and automated testing equipment with high energy efficiency requirements.

 

4. Quieter, low noise and low vibration

When a traditional motor is running, the magnetic field interaction between the iron core stator and the rotor easily causes electromagnetic noise, and mechanical friction also causes additional vibration. However, the Coreless Motor has a more uniform magnetic field distribution and a coreless structure that reduces electromagnetic resistance torque fluctuations, runs more smoothly, has almost no mechanical friction, and significantly reduces noise levels. This makes it superior in medical equipment, laboratory instruments, high-end consumer electronics and other occasions with high requirements for quietness.

 

5. More precise control, suitable for precision equipment

Since coreless motors have excellent dynamic response performance and can more accurately control current and torque, they have obvious advantages in fields that require highly precise control. For example, in the fields of medical surgical robots, precision testing instruments, automatic optical equipment, etc., coreless motors can achieve more precise motion control and improve the operating accuracy and stability of the equipment.

 

 

As people pay more and more attention to Coreless Motors and technology continues to innovate, in the future, Coreless Motors will inevitably usher in new breakthroughs in cost, technology and application areas.

 

1. Higher cost performance, further cost optimization

Traditionally, coreless motors are more expensive than ordinary motors due to the use of high-precision winding technology and high-performance magnetic materials. However, with the upgrading of manufacturing technology, the improvement of production efficiency and the reduction of material costs, the price of coreless motors is expected to be further optimized in the future, making them more easily adopted in consumer electronics, medical equipment, intelligent robots and other fields.

 

Currently, VSD has begun to adopt automated winding technology to reduce labor costs, while optimizing the ratio of magnetic materials and improving the overall production yield. In the future, with large-scale mass production and supply chain optimization, the cost of Coreless Motors is expected to drop further, thereby promoting more industries to achieve technological upgrades.

 

2. High power density development to meet extreme working conditions

With the development of science and technology, many devices have increasingly stringent requirements for motors, requiring both miniaturization and lightness, as well as high power and high torque. In the future, VSD's coreless motors will further optimize the winding structure and magnetic circuit design to improve power density, making them smaller but with stronger output, suitable for aerospace, micro drones, precision medical instruments and other fields with extremely high power density requirements.

 

In terms of technology research and development, VSD has never stopped for more than ten years. With the development of business, our R&D engineer team has continued to grow, and the annual investment in R&D has also continued to increase. In the future, VSD will focus on developing Coreless Motors with higher power density, higher efficiency and more stability to provide customers with more competitive products.

 

3. Wider application scenarios to promote the upgrading of multiple industries

At present, coreless motors have been used in precision instruments, medical equipment, robots, drones and other industries, and in the future, their application scope will be further expanded. For example:

New energy field: Coreless Motors can be used in solar tracking systems, energy storage equipment, etc. to improve energy utilization.

 

Automated logistics: As the demand for high dynamic response and high-precision positioning of warehouse robots, AGV carts, etc. grows, the advantages of Coreless Motors will be further highlighted.

 

Consumer electronics: In the fields of high-end audio, smart camera equipment, electronic stabilization systems, etc., the low noise and precise control characteristics of Coreless Motors will bring better user experience.

 

Healthcare: Coreless motors will be widely used in rehabilitation robots, precision surgical equipment, wearable medical devices, etc., helping the medical industry achieve higher precision and more reliable operations.
