What Is a Magnetic Wheel?

Magnetic wheels are a common wheel design for wall-climbing robots. Usually equipped with powerful magnets or a magnetic system that can be magnetically attached to metal or other specific surfaces. The magnetic wheels can provide stable adhesion, and the robot can use this adhesion to move on the wall.


What Are the Types of Magnetic Wheels?

Type Definition Effect
Permanent magnet wheel Magnetic wheel using permanent magnets to generate magnetic force Can provide reliable adhesion and stability
Electromagnetic wheel Magnetic wheel that uses electromagnets to generate a magnetic field Adjust the magnitude and direction of the magnetic force by controlling the flow of electric current
Magnetic wheel Magnetic wheel that levitates and moves using maglev technology Let the magnetic wheel levitate and move on the surface by controlling the size and position of the magnet
Magnetic pedal Magnetic wheels with segmented magnetic surfaces Control the magnitude and state of the magnetic force of each pedal to move the magnetic wheel
Adaptive magnetic wheel Magnetic wheel that adjusts the magnitude of the magnetic force and adhesion according to surface conditions and environmental changes Automatically adjusts to different types of surfaces for optimal mobility

These are some common types of magnetic wheels, and different types are suitable for different applications and environments. Which type of magnetic wheel to choose depends on the needs of the robot and the manufacturer's design choices.


What Is the Purpose of Making a Magnetic Wheel?

Magnetic wheels are manufactured for movement and adhesion on vertical or inclined surfaces. Magnetic wheels have the following advantages and application scenarios:

Wall climbing and vertical movement

Magnetic wheels can provide a strong magnetic attraction, allowing the robot to move on walls, ceilings or other vertical surfaces. This capability is very useful in many applications such as building maintenance, industrial inspection, cleaning services, etc.

High reliability and stability

Magnetic wheels provide reliable adhesion and stability, enabling the robot to move safely on different surfaces. Compared to other locomotion mechanisms, such as wheels or tracks, magnetic wheels can adapt and move better on complex or irregular surfaces.

Defy gravity challenge

Magnetic wheels overcome the challenge of gravity by utilizing magnetic attraction, allowing the robot to move on inclined surfaces. This is important for robots working on slopes, sloping roofs or other sloping surfaces.

Contactless movement

The movement of the magnetic wheels is achieved by magnetic attraction, which means that they can move without physical contact. This is useful for certain applications where surface abrasion or contamination needs to be avoided.

Special environment application

Magnetic wheels can be used in some special environments, such as vacuum environment, high or low temperature environment, because they are not affected by surface conditions or environmental conditions.

In summary, fabricating magnetic wheels can provide the ability to move on vertical or inclined surfaces and solve some of the challenges faced by traditional locomotion mechanisms. This makes magnetic wheels an important choice for robotic applications in many fields.


What Is the Material of the Magnetic Wheel?

The material of the magnetic wheel is usually composed of multiple components. The following are the four parts that a magnetic wheel consists of:

Magnet material

Magnet materials are used to make the magnets or magnetic systems in the wheels to generate a strong magnetic field. Common magnet materials include permanent magnet materials such as neodymium iron boron (NdFeB) magnets or cobalt magnet materials. These materials have a high energy product and strong magnetic force, which can provide stable adhesion.

Wheel body material

The main body of the magnetic wheel is usually made of a lightweight material with good mechanical properties to provide structural strength and stability. Commonly used materials include metal alloys (such as aluminum alloys, titanium alloys) and engineering plastics (such as polyamides, polycarbonates). The weight, stiffness and durability of the wheel need to be considered when choosing the material.

Wheel shell protection material

To protect the magnetic wheel and increase its durability, a protective wheel housing is usually installed around the wheel. This wheel shell is usually made of abrasion-resistant, impact-resistant material to protect the wheel from damage. Common materials include rubber, silicone, or other elastic materials.

Wheel contact surface material

The contact surface of the magnetic wheel needs to provide enough friction and adhesion to ensure stable movement of the robot on the surface. These materials are generally wear resistant and have good friction properties. Common choices include rubber, polyurethane, silicone, or other specialty friction materials.

These material choices are based on the functional requirements of the wheel and the manufacturer's design choices. A specific magnetic wheel design may use different combinations of materials to achieve the desired performance and functionality.


What Are the Safety Requirements for Magnetic Wheels?

The safety requirement of the magnetic wheel is to ensure the safety of personnel and the environment during use and operation. The following are some common safety requirements for magnetic wheels:

Electromagnetic compatibility (EMC)

Magnetic wheels may generate electromagnetic fields during operation and therefore need to comply with relevant electromagnetic compatibility standards. These standards ensure that the operation of the magnetic wheel does not interfere with surrounding electronics or other systems.

Structural safety

Magnetic wheels must be designed to meet structural safety requirements to ensure adequate strength and durability under normal use and expected working loads. This includes proper material selection, rational structural design and necessary strength analysis.

Electrical safety

If the magnetic wheel contains electrical components (such as electromagnets), it needs to comply with relevant electrical safety standards to ensure the safety of the electrical part. This includes insulation protection, protection against electric shock risks and overheating, etc.

Magnetic field safety

The magnetic field generated by the magnetic wheel should comply with the safety limits for personnel and the environment. This is to avoid adverse effects on human health or damage to surrounding equipment and magnetic induction materials (such as tapes, credit cards, etc.).

Overload protection

Magnetic wheels may be exposed to loads beyond their design. Therefore, overload protection measures should be considered to prevent the wheels from being damaged or dangerous under overload conditions.

Control system security

If the magnetic wheel is equipped with a control system, such as a sensor for adjusting the magnetic force or monitoring the attachment state, then the safety and reliability of the control system must be ensured to avoid accidents or operating errors.

These are some common safety requirements for magnetic wheels, and specific requirements may vary by application and region. Manufacturers should comply with applicable safety standards and regulations when designing and manufacturing magnetic wheels, and ensure that they have undergone the necessary tests and verifications to verify their safety. In addition, users should strictly follow the relevant safety guidelines and instructions when operating and using the magnetic wheel.


Why Is It Important to Use Magnetic Wheels on Ships?

The use of magnetic wheels in hull inspections is important for several reasons:

Fast and non-destructive inspection

Magnetic wheels can be used for fast non-destructive inspection of magnetic materials such as steel in hull structures. By placing the magnetic wheel on the hull, it can generate a strong magnetic force to make the magnetic flaw detector adsorb on the possible defects or cracks. This approach can help detect hidden structural issues such as metal fatigue, cracks, corrosion or weld quality issues.

Efficiency and reliability

Compared with traditional visual inspection or other non-destructive testing methods, magnetic wheel inspection has higher efficiency and reliability. It covers large areas of hull quickly and provides accurate inspection results. At the same time, due to the use of magnetic adsorption without physical contact, interference and damage to the hull can be reduced.

Detect hidden defects

Imperfections in the hull structure may arise due to external factors (such as seawater corrosion) or internal stresses (such as vibrations and loads of the ship). These defects may not be visible on the surface, but produce magnetic field disturbances on the magnetic material. Magnetic wheel inspection can help detect these hidden flaws to prevent potential structural failures and safety risks.

Early detection of structural problems

By conducting regular hull inspections with magnetic wheels, structural problems can be detected and identified early so that corrective actions can be taken in a timely manner. This helps to extend the life of the hull, improve the safety and reliability of the vessel, and reduce repair and maintenance costs.

Regulatory requirements

In some shipping industries, such as the regulations of the Classification Society, the periodic inspection and maintenance of ships may require the use of magnetic wheels for hull inspection. This is a requirement to ensure the integrity of the hull structure and the safe operation of the ship.

In summary, the use of magnetic wheels for hull inspection plays an important role in providing fast, accurate and reliable inspection results. It is capable of detecting hidden structural problems, discovering and repairing potential defects in advance, thereby improving the safety, reliability and maintenance efficiency of ships.
