Electro-Magnets

Eclipse Magnetics understand the needs of the product designer, machine designer, electrical engineer, safety manager and end user.

Electro-holding magnets can be simple electromagnets or electro-permanent magnets.

Electromagnets are a wound copper coil with a central steel core within a steel housing– they only create magnetism and clamp onto mild steel when a dc electrical current is present (energise to hold).

Electropermanent magnets are electromagnets with permanent magnets inside them as well – the magnet clamps to the mild steel when no current is applied but when the dc current is applied the magnetic paths change and clamping is stopped (energise to release). The energise to release electromagnets are always "on" when no current is present.

Typical Applications for Electro Magnets

• • Machine tools • Door locking / holding • Actuators • Feeder mechanism, Short stroke / high force operation

  • Automation e.g. Textile machinery, Packaging machinery, Office machinery • Grill locking • Transformers • Remote hold / release
