Linear motors and wire bonding machines including the same

A wire bonding system comprising:

• a bond head assembly carrying a wire bonding tool;
• and
• a linear motor system for driving the bond head assembly along a first horizontal axis, the linear motor system including (a) a moving magnet assembly including (i) a magnet track, (ii) a first plurality of permanent magnets coupled to the magnet track, and (iii) a second plurality of permanent magnets coupled to the magnet track and arranged below the first plurality of permanent magnets, wherein each of the first plurality of permanent magnets is positioned directly above a corresponding one of the second plurality of permanent magnets in connection with the magnet track to form a magnet pair such that the magnet track is not between at least a portion of the permanent magnets of the magnet pair, wherein the magnet track includes a plurality of tab portions, and each of the first plurality of permanent magnets and the second plurality of permanent magnets includes a stepped portion configured to mate with corresponding ones of the plurality of tab portions, (b) a first coil assembly arranged above the moving magnet assembly, the first coil assembly including a first plurality of teeth having first slots therebetween, the first coil assembly also including a first plurality of coils at least partially disposed in at least a portion of the first slots, and (c) a second coil assembly arranged below the moving magnet assembly, the second coil assembly including a second plurality of teeth having second slots therebetween, the second coil assembly also including a second plurality of coils at least partially disposed in at least a portion of the second slots.
