摘要： A linear motor is provided. The linear motor includes 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. The linear motor also includes a first coil assembly arranged above the moving magnet assembly. The first coil assembly includes a first plurality of teeth having first slots therebetween. The first coil assembly also includes a first plurality of coils at least partially disposed in at least a portion of the first slots. The linear motor also includes a second coil assembly arranged below the moving magnet assembly. The second coil assembly includes a second plurality of teeth having second slots therebetween. The second coil assembly includes a second plurality of coils at least partially disposed in at least a portion of the second slots.

摘要： A wire bonding system is provided including a bond head assembly carrying a wire bonding tool. A wire bonding system also includes a linear motor system for driving the bond head assembly along a first horizontal axis. The linear motor system includes a moving magnet assembly including a magnet track and a plurality of permanent magnets coupled to the magnet track; a coil assembly arranged around the moving magnet assembly, the coil assembly including a plurality of teeth having first slots therebetween, the coil assembly also including a plurality of coils at least partially disposed in at least a portion of the slots; a position encoder system; a damper element positioned between the coil assembly and a base structure of the linear motor system; and a spring element positioned between the coil assembly and the base structure of the linear motor system.
