Abstract
A tufting machine has a reciprocating needle bar which may be shifted laterally by a drive which includes at least one linear motor. Each linear motor has two major elements which may be coupled together electromagnetically. One of the elements is connected to a fixed portion of the tufting machine and another of the elements is connected to the needle bar. When electrical power is supplied to the motor, the element connected to the needle bar moves relatively to the other thereby moving the needle bar.
