DETAILED DESCRIPTION OF THE INVENTION
Based on the above described principles, the following functions and economic gains can be obtained by the electrical machine with inter-cross coupled magnetic circuit: 1) For large scale machines in small quantities, the
magnetic circuit structure is inter-cross combined by
independent iron core laminates with smaller surface
area instead of the conventional joining method,
therefore the inter-crossed combination has radial
ventilation holes which is different from the radial
closed type magnetic circuit structure by the
conventional joining method, thereby it has better heat
dissipation and the forming dies employed is smaller
than the conventional integrated type required, whereby
the cost of dies can be lowered and the large scale
punching equipment is not needed.
2) Since the armature which constitutes the interactive
electrical machine structure faces the radial
ventilation holes directly, it benefits the heat
dissipation of the electrical machine.
The innovative design is for application in the rotational or linear type generators, motors or electrical magnets or others, wherein the field magnetic poles are constituted by the electrical energy excited windings or the permanent magnets to interact with the coupled interactive electrical machine structure, and to couple with the magnetic flux between the magnetic poles through the inter-crossed interpole magnetic circuits, thereby to constitute a high heat dissipation electrical machine structure, whereof it is mainly comprised of the following:

conductivity and can be configured in either single end
or double-end extension embodiments, wherein it is
characterized in that the coupling positions between the
interpole magnetic circuits in different pointing
directions and the magnetic poles can be configured in
either symmetrical or asymmetrical inter-cross shapes,
