1. the central part of a fleshy fruit, containing the seeds.
2. the central, innermost, or most essential part of anything.
3. the piece of iron, bundle of iron wires, or other ferrous material forming the central or inner portion in an electromagnet, induction coil, transformer, or the like.

Manufacturers in various industries are giving high preference to soft magnetic composites over traditional laminated core owing to the reduction in bearing current, no eddy current losses, and easy recyclability of the stator.
where [[rho].sub.m] is the specific electrical resistivity of the material of the magnetic core (according to reference data, for example GOST 21427.2-83), l is the size of the area of the magnetic core in the direction perpendicular to the direction of passage of the main magnetic flux (for the toothed areas--the average width of the teeth, for a jar of electric machines--the thickness of the yoke in the radial direction); t is thickness of the sheet of the laminated core; [k.sub.f] is a coefficient of the form of the core (correction coefficient).
The benefits of replacing the conventional laminated core in an electric machine with the SMC are considerable, and include reduced high frequency tooth ripple losses since the SMC has essentially no eddy current losses, modular construction allows the possibility of easy removal of an individual modular unit for quick repair or replacement, stator is easily recyclable, reduced bearing currents.
While the stator coils will usually be replaced, there may also be an issue with the laminated core and the rotor assembly.
Perriard, "Eddy current power losses in a toroidal laminated core with rectangular cross section, " ICEMS 2009, International Conference on Electrical Machines and Systems, 1-4, 2009.
This causes a magnetic flux distribution into the soft iron (SiFe) laminated core. When the system is energized, the occurred magnetic flux passes through into the sample.
The machine's hot-melt roller coater, semi-automatic lay-up conveyor, upper veneer rack conveyor and vinyl roll applicator ensure the upper veneer and lower laminated core fit properly.
Since the turn of the year, the firm has embarked on projects with several aerospace companies, supplying laminated core packs.
1+N+1 = Type II (Layer 1:2 microvias with buried vias in a laminated core)
While it is easy to talk about diamond shape or cantilever mass, it must be remembered that that fixed coil structure, in the cartridge body, is idiosyncratic to each manufacture in terms of the fixed coils, the laminated core, the pole pieces, and the manner in which these items are deployed.
The company stocks low loss laminated core material, hardware and a variety of construction materials to offer custom designed transformers at price and lead-times more typical of off the shelf products.
