Magnetic Wheels Assemblies
What Are Magnetic Wheels?
Magnetic wheels are specialized wheel assemblies that integrate permanent magnets to generate magnetic attraction. Depending on their magnetic circuit and structural design, they can attach to suitable ferromagnetic surfaces. This allows equipment to move on vertical, inclined, and other suitable surfaces.
A magnetic wheel typically consists of permanent magnets, a wheel body, and related structural components. The magnet arrangement, wheel dimensions, and wheel surface design all affect its holding force, traction, and overall performance.
What Are the Advantages of Magnetic Wheels?
Equipment operating on vertical and inclined surfaces needs strong adhesion, stable movement, and reliable performance over time. TOPMAG magnetic wheels offer the following advantages:
Wide Range of Holding Forces: From light-duty to heavy-duty applications, the holding force can be selected or designed to match the equipment load. The standard series offers vertical holding forces from 5 to 200 kg.
Stable Magnetic Attraction: Multi-pole magnetic designs help optimize the magnetic field distribution on the working surface. This supports stable magnetic attraction and traction.
Material Options for Different Temperatures: NdFeB and SmCo magnets can be used. The appropriate magnet grade can be selected based on the operating temperature.
Multiple Wheel Surface Options: Options include stainless steel covers, knurled surfaces, and polyurethane or rubber coatings. These designs meet different needs for cleaning, traction, slip resistance, and surface protection.
Compact and Lightweight Design: A compact structure helps reduce the overall equipment load and improve operating efficiency.
Customization to Meet Your Needs: Wheel dimensions, connection structures, holding force, and surface materials can be customized to suit specific equipment requirements.
What Are the Different Types of Magnetic Wheels?
Magnetic wheels can be customized based on wheel surface materials, surface designs, and assembly structures. The following categories show common designs and customization options.
| Type | Features | Typical Applications |
|---|---|---|
| Stainless Steel-Covered Magnetic Wheels | Stainless steel outer covering for easy cleaning and added protection. Used in the standard KMCW series. | Wall-climbing robots, cleaning equipment |
| Knurled Magnetic Wheels | Knurled wheel surfaces increase friction and traction. | Equipment requiring greater traction |
| Rubber-Coated Magnetic Wheels | Polyurethane or rubber coatings increase friction and help protect the contact surface. | Coated surfaces and applications requiring slip resistance or noise reduction |
| Custom Magnetic Wheels | Wheel bodies, shaft holes, connection structures, wheel surfaces, and holding forces designed to meet equipment requirements. | Custom industrial equipment and specialized applications |

Frequently Asked Questions (FAQ)
Can Magnetic Wheels Work on Painted, Rusty, or Curved Surfaces?
Yes, but coatings, rust, and curved surfaces may reduce magnetic holding force.
How Do I Choose the Right Magnetic Wheel Type?
Stainless steel-covered wheels offer protection, knurled wheels improve traction, and rubber-coated wheels provide grip and surface protection.
What Is the Operating Temperature of Magnetic Wheels?
It depends on the magnet grade and assembly design. Please provide your operating temperature for evaluation.
How Do I Maintain Magnetic Wheels?
Clean debris regularly and inspect the wheel surface and fasteners for wear or looseness.
What Materials Can Magnetic Wheels Attach To?
Magnetic wheels work on ferromagnetic materials such as carbon steel. They generally do not provide effective magnetic attraction to aluminum, copper, or plastic.
