    摘要: Methods and apparatus for identifying the occurrence of fusing electrical attachment during fusing operations are provided. After a conventional fusing operation is complete, an electrical signal is applied to the fusing electrode while the fusing electrode is returned to its home position. The electrical signal is monitored to determine whether a circuit path exists from the fusing electrode through the fused conductors to the ground electrode. The presence of a path would indicate that the fusing electrode has become attached to the fused conductors. An alternate embodiment is also described in which the force required to withdraw the fusing electrode is monitored while the electrode is returned to its home position. If the measured force does not fall within predetermined limits, or if the measured force varies during electrode movement, fusing electrode attachment has occurred.

    摘要: An improved fusing machine is provided that allows commutators to be balanced during the fusing process. Commutator tangs are compressed onto coil leads to form lead connections. The fusing machine compresses the tangs to varying degrees relative to the shaft. The commutator can be balanced during fusing by compressing tangs to a common radial position or by compressing diametrically opposed tangs to the same extent.

    摘要: In the performance of fusing operations which involve the application of force and heat to a workpiece, the heat being generated at least in part by electrical resistance heating resulting from passage of an electrical current through an electrical circuit which includes the workpiece and typically also a fusing electrode, the fusing cycle is controlled at least in part on the basis of measurements of the resistance of the above-mentioned circuit during the fusing operation. If desired, the resistance measurements may be corrected to eliminate or at least substantially reduce the contribution of electrode resistance so that the fusing operation is controlled on the basis of the resistance of the workpiece.

    摘要: 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.

    摘要: Methods and apparatus for fusing together electrical conductors to a commutator are provided. A precise, timed, and controlled delivery of electric current to the fusing electrode of the fusing machine is achieved. A generic supply signal is converted into a precise and constant input signal through the use of monitoring and feedback techniques, which compare the current status of the physical and electrical phases of the fusing operation to various predetermined fusing profiles to determine the proper application of current to the fusing electrode.

    摘要: 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.
