Abstract
Methods and apparatus for fusing armature wires to a commutator, and fusing stator lead wires and stator hooks, are provided. An electrode assembly having a screw mechanism converts the rotational motion of a motor into a translational motion of the fusing electrode. A microprocessor-based control circuit receives electrode force and displacement data from a load cell and an encoder, respectively, to control the fusing operation. The fusing operation is performed according to a predetermined force or displacement function that is stored in the control circuit.
