ABSTRACT:
Methods and apparatus for monitoring the temperature of a workpiece during fusing operations are provided. The apparatus includes a temperature sensor which monitors the temperature of a commutator bar being fused and outputs an electrical signal corresponding to that temperature. The electric current supplied to the fusing electrode can be interrupted or modified if the temperature of the commutator bar exceeds a predetermined temperature. In this manner, fusing operations can be interrupted if the temperature of the commutator bar approaches a temperature at which other components of the workpiece, such as the core material will be adversely affected. The temperature sensor preferably contacts the workpiece to conduct heat to a sensing element.
