Circular Lifting Magnet By Electro Magnetic Flux Industries

Mechanical construction of EMF -Technology high capacity lifting magnets is very sturdy to meet toughest demands in service. The one piece magnet body is cast from high-grade dynamo steel or Mild Steel. Underneath, between centre and outer poles, the magnet body is closed by sturdy, cast and rib-reinforced non-magnetic austenitic manganese steel plate. Fastening at the centre pole is affected by means of a shrunk-on ring and at the outer pole by locking ring. The standard three-fall chain suspension, designed with common suspension ring is rated to meet all normal duty loads. Special change is available on request for extremely heavy loads. Two lugs for guide ropes are fitted as standard.

COILS

Standard exciter coils are wound with Anodised Aluminium conductor or fiber glass covered varnish bonded Aluminium conductor. Coils wound with anodised Copper conductor offer the following advantages:

Greater filling factor
Better heat conductivity.
Higher resistance to thermal strain.

Coils are cast into their magnet body with a special resin compound of excellent heat conductivity and thus rigidly fixed in position. In special cases, coil can be furnished with copper conductor. Use of special resins loaded with fillers as sealing compound ensures reliable conduction of heat to the magnet surface, maintaining high magnet performance over long, continuous service. All insulation materials confirm to class " H"
