ABSTRACT:
The invention provides a driving apparatus for needle of a knitting machine wherein a coupling operation of a stator assembly and a moving assembly can be facilitated and a smooth movement of the moving assembly is assured. The driving apparatus includes a linear motor for reciprocally moving the needle. The linear motor include a pair of stator assemblies each having first magnet means thereon and opposed to each other with a space left therebetween in the horizontal direction intersecting a vertical direction, a moving assembly having second magnet means and disposed vertically between the stator assemblies so as to move in a direction of movement of the needle, and coupling means for supporting the moving assembly on at least one of the stator assemblies. The coupling means supports the moving assembly on at least one of the stator assemblies at a location either above or below a position at which the second magnet means is arranged. A position sensor detects a position of the moving assembly with respect to the stator assemblies.
