Abstract: A method of manufacturing a can assembly of a coreless AC linear motor is provided. The method includes the steps of providing a workpiece and gouging out material from the workpiece to form a deep groove in the workpiece. The workpiece having the deep groove forms a can. The method also includes providing a plurality of coreless coils and arranging the plurality of coreless coils in a straight line. The method also includes forming the plurality of coreless coils into a flat plate-shaped block using resin or adhesive. The flat plate-shaped block forms a coil assembly. The method also includes inserting the coil assembly into the deep groove of the can. The can assembly comprises the can and the coil assembly.

Abstract: A coreless AC linear motor, including a magnet assembly forming a magnetic gap, and a can, the can further including a coil housing section forming a deep groove. The motor also includes a plurality of coreless coils inserted into the deep groove and arranged in a straight line inside the magnetic gap, and a cover body for sealing the can.

Abstract: A fluid flushing device for an electroerosion apparatus for flushing a machining gap (32) with a dielectric fluid comprising a coupling block (46) having a supply conduit (19;45) connected to a supply source of dielectric fluid at one end. A pallet (1) for carrying the workpiece (14) includes a passage (17,28;41), and is equipped with a flexible hose (30) having a presetable flushing direction or orientation. The other end of the passage couples with the supply conduit when the automatic pallet changer (80) loads the workpiece on the apparatus through the pallet, so that continuous automatic operation can be realized.
