  • Patent number: 4713883
    Abstract: In a production line for electric motor stators, the stators are rigidly fixed individually, onto respective individual pallets which advance along conveyor belts, in proximity to which the necessary stator-working stations are located; mechanical means are also provided for removing the pallets from the belts and handling them so that the respective stators become disposed in positions corresponding with the working stations located along the line, and in proximity to which said mechanical means are provided.

  • Patent number: 4651086
    Abstract: A method, and apparatus, for determining the resistance of the electrical connections between coils and the bars of a commutator for electric motors as well as the resistance of the coils themselves includes applying appropriate voltages to the commutator bars to simulate a cut in the winding thus permitting determination of the connection resistance independently of the coil resistance. After the connection resistance has been determined, the measurement of an additional voltage permits the determination of the coil resistance.

  • Patent number: 4579291
    Abstract: An adjustable chuck for armature winding machines employs a pair of stationary longitudinal deflectors or wings and a separate pair of frontal deflectors or wings. At least one of the frontal deflectors is movable independently of the longitudinal deflectors so that the chuck can be adjusted to accommodate armatures having cores of various different lengths. Regardless of whether the frontal deflectors have been positioned to accommodate a long or short armature, they cooperate with the longitudinal deflectors to form a continuous wire guide path for a wire being wound around the armature.

  • Patent number: 4027375
    Abstract: A device for angularly centering a member having an annular toothed formation, for example an electric motor commutator prior to mounting the commutator on a rotor shaft, comprises a centering bracket located in the path of movement of the member. The bracket has, at its upstream end, a ramp, followed by two laterally spaced centering profiles. If a tooth of the member engages the ramp, the bracket is resiliently deflected and the tooth thereafter engages one of the centering profiles. Alternatively, the tooth will directly engage the other of the centering profiles. When the member has been centered by either one of the two profiles, it is held in its centered position within a grooved seat to enable further operations to take place.

  • Patent number: 4001539
    Abstract: A welding machine is described in which current to the welding electrodes is controlled by an S.C.R. unit. The S.C.R. unit is provided with control pulses in accordance with a predetermined program so that the power fed to the welding electrodes should follow a predetermined characteristic. A simulator is provided to simulate from the control pulses, the energy characteristic that the welding electrodes should follow. The actual energy characteristic of the electrodes is monitored. If the actual energy characteristic falls outside the simulated characteristic, a fault signal is generated.
