Component Specifications

Definition
A precision-engineered magnetic assembly consisting of permanent magnets or electromagnets arranged within a protective housing, designed specifically for integration into magnetic drums and rollers. This component generates a consistent magnetic field across the drum surface to attract, hold, or separate ferrous materials in industrial processes. It features optimized magnetic circuit design, thermal management, and mechanical mounting interfaces for reliable operation in demanding environments.
Working Principle
Operates by generating a magnetic field through permanent magnets (neodymium, ferrite) or electromagnets. When integrated into a rotating drum/roller, the magnetic field attracts ferrous materials from conveyed materials. The magnetic force is maintained across the working surface while non-magnetic materials continue along the conveyor path. Electromagnetic versions allow adjustable field strength through current control.
Materials
Core: Neodymium (NdFeB) N42-N52 grade, Ferrite (SrFe12O19), or AlNiCo alloys. Housing: 304/316 stainless steel or powder-coated carbon steel. Insulation: Class H (180°C) epoxy or polyimide for electromagnetic coils. Structural components: Aluminum alloy or engineering plastics for non-magnetic parts.
Technical Parameters
  • Weight 5-50kg depending on drum diameter
  • IP Rating IP65 minimum
  • Field Uniformity ±10% across working surface
  • Magnetic Strength 800-5000 Gauss surface field
  • Power Consumption 0-500W (electromagnetic)
  • Temperature Rating -40°C to 150°C operational
Standards
ISO 9001, DIN 1543, IEC 60404-8-1

Frequently Asked Questions

What maintenance does a magnetic core assembly require?

Minimal maintenance: periodic inspection for physical damage, cleaning of accumulated ferrous debris, and verification of magnetic strength (annual gauss meter check). Electromagnetic versions require coil resistance testing.

Can magnetic strength be adjusted in permanent magnet assemblies?

No, permanent magnet assemblies have fixed strength. For adjustable applications, electromagnetic cores with variable current control are recommended.

What is the typical lifespan of these assemblies?

15-20 years for permanent magnet versions with <5% flux loss. Electromagnetic versions: 10-15 years depending on insulation degradation and duty cycle.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
