Magnetic Coupling
View system integration details
This page explains how Drive magnet assembly is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
The magnetic component within a magnetic coupling that transmits torque from the drive side to the driven side through magnetic fields.
Technical details and manufacturing context for Drive magnet assembly
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Torque Capacity | 50–500 N·m | Determines maximum transmissible torque |
| Operating Temperature | -40–150 °C | Above 150°C may demagnetize |
| Magnet Material | N35–N52 grade | Higher grade increases torqueGB/T 13560 |
| Magnet Outer Diameter | 50–200 mm | Fits standard coupling sizes |
| Magnet Inner Diameter | 20–100 mm | Matches shaft diameter |
| Axial Length | 30–150 mm | Affects torque and inertia |
| Radial Runout | 0.05–0.1 mm | Tighter runout reduces vibrationISO 1101 |
| Surface Magnetic Field | 3000–5000 G | Indicates magnetic strength |
| Maximum Operating Speed | 3000–6000 rpm | Limited by centrifugal stress |
| Weight | 1–10 kg | Depends on size and material |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| pressure: | Up to 100 bar (standard), up to 300 bar with reinforced housing |
| other spec: | Max torque transmission: 500 Nm (standard), up to 2000 Nm with custom designs; Gap tolerance: ±0.5 mm; Slurry concentration: ≤40% solids by weight |
| temperature: | -40°C to 150°C (standard), up to 250°C with high-temp magnets |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

Manufacturer profiles associated with Drive magnet assembly.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
According to the directory data, the torque capacity range is 50–500 N·m. However, the exact value depends on the specific model and application. Always verify with the legal manufacturer or supplier.
The materials on file include Neodymium Iron Boron (NdFeB), Samarium Cobalt (SmCo), and Alnico. Each has different magnetic properties and temperature stability. The magnet material grade (e.g., N35–N52) is specified per GB/T 13560 and should be confirmed for your application.
The operating temperature range is -40 to 150°C. Above 150°C, demagnetization may occur. For high-temperature applications, consult the manufacturer to select a suitable magnet material.
Radial runout is specified as 0.05–0.1 mm per ISO 1101. This parameter affects vibration and should be checked during installation. Always refer to the manufacturer's documentation for the exact value for your model.
