Abstract

The invention relates to a stator unit (3) for moving at least one shuttle (4) of an electromagnetic drive system (1) and to an electromagnetic drive system (1) comprising at least one stator (3) forming the stator (2). The stator unit (3) comprises an arrangement of drive coils (7), which are energized by a drive current (l_o) in an area of the at least one shuttle (4) to generate an electromagnetic field, which interacts with a magnet unit (5) arranged on the at least one shuttle (4) to move the at least one shuttle (4). The drive coils (7) are configured as elongated flat coils (8), comprising conductors (14, 15, 16, 21, 22, 23) arranged in winding layers (12, 19) being electrically insulated from each other by an electrically non-conductive insulating medium (17). An elongated flat coil (8), which is used as drive coil (7) arranged on the stator unit (3), comprises at least one winding layer (12, 19), usually two or more. In the at least one winding layer (12, 19) at least one winding (13, 21) is arranged, which comprises a forward-conductor (14, 21) and a return-conductor (15, 22) being electrically connected with one another by a cross-connection (16, 23). Furthermore, the forward-conductor (14, 21) and/or the return-conductor (15, 22) of the at least one winding (13, 21) are divided into at least two sub-conductors (141, 142, 151, 152, 211, 212, 221, 222) arranged next to each other in parallel in the at least one winding layer (12, 19) of the elongated coil (8). By dividing the forward-conductor (14, 21) and/or the return-conductor (15, 22) into at least two sub-conductors (141, 142, 151, 152, 211, 212, 221, 222), losses, in particular eddy current losses and heat losses, during operation of the electromagnetic drive system (1) are reduced and the efficiency of the stator unit (3) and the whole electromagnetic drive system (1) is increased.
