Patent number: 5664317Abstract: Electric motor stators can have coils wound on their poles which coils have more turns than the poles could normally support by augmenting the pole with additional structures to support the added coil turns. The additional structures can be only temporarily associated with the stator, e.g., by adding them to the winding shrouds which are customarily applied to the stator during winding. Alternatively these additional structures can be permanent but non-magnetic portion of the stator, e.g., by adding them to the terminal board members of the stator.Type: GrantFiled: February 14, 1996Date of Patent: September 9, 1997Assignee: Axis USA, Inc.Inventors: Massimo Ponzio, Massimo Lombardi

Patent number: 5664735Abstract: The balance of rotors for dynamo-electric machines (e.g., electric motor armatures), which are wound with two diametrically opposite, simultaneously applied coils of wire, is improved by ensuring that wire is fed to both coils in substantially similar quantities. This can be accomplished by monitoring the lengths of the two wires as they are fed to the armature using wire sensors located adjacent to the flyer. Alternatively, wire sensors can be provided to monitor the rate at which wire is being fed towards respective flyers and to measure the rate of change of the lengths of those portions of the wires that are supported by the winding machine dancer arms. A control system processes the measurements from these sensors. A wire tensioner having a hysteresis clutch is also provided that allows the tension applied to a wire being wound to be adjusted rapidly. The wire tensioner also picks up slack that may develop in the wire.Type: GrantFiled: September 12, 1996Date of Patent: September 9, 1997Assignee: Axis USA, Inc.Inventors: Federico Sbalchiero, Massimo Lombardi, Mauro Tarchi

Patent number: 5572787Abstract: Armatures for dynamo-electric machines are balanced during manufacture by measuring the unbalance of the armature assembly prior to winding the coils on the armature. The numbers of turns of wire in at least some of the coils subsequently wound on the armature are then adjusted so that the unbalance of the resulting coils compensates for the unbalance of the armature prior to coil winding. In addition, masses may be added to the armature to ensure that it is balanced dynamically as well as statically.Type: GrantFiled: August 30, 1993Date of Patent: November 12, 1996Assignee: Axis USA, Inc.Inventors: Giuseppe Cardini, Massimo Lombardi

Patent number: 5557838Abstract: A wire winding machine is provided that allows the connection of electric motor armature coil leads to slot-type commutators. The machine uses rotations of a flyer and rotations of the armature to perform much of the needed movement during the lead attachment process. The system uses a guide member to guide the wire into the commutator slots during rotation of the flyer. The guide member guides wire from the flyer toward the slots during both the initial insertion of the wire and the subsequent process of forming a loop in the wire.Type: GrantFiled: August 5, 1994Date of Patent: September 24, 1996Assignee: Axis USA, Inc.Inventors: Massimo Lombardi, Sabatino Luciani, Massimo Ponzio, Graziano Quirini

Patent number: 5493770Abstract: Dynamo-electric machine armatures which have commutators and cores that are axially close to one another are wound with the aid of wire guiding hooking plates that are inclined to reach into the portion of the commutator that is axially adjacent to the core where the coil leads must be attached to the commutator. The hooking plate may also perform an additional extension motion in order to press the coil leads out of the way of a subsequent fusing operation. This function may alternatively be performed by a separate pusher member which is either associated with the hooking plate or independent of the hooking plate. The fusing electrode may be specially shaped to facilitate performing fusing operations axially close to the armature core.Type: GrantFiled: March 25, 1994Date of Patent: February 27, 1996Assignee: Axis USA, Inc.Inventors: Luciano Anichini, Massimo Lombardi

Patent number: 5484114Abstract: Electric motor armatures are wound by moving a wire dispensing member relative to the armature so that the wire dispensing member itself guides the wire precisely into position on the armature and so that no additional wire guides or shrouds are needed to guide the wire and keep it out of contact with portions of the armature that it should not contact. The relative motion between the armature and the wire dispensing member is preferably under programmable control so that the apparatus can be readily reprogrammed when different types of armatures are to be wound. Specially shaped wire dispensing members may be employed.Type: GrantFiled: May 1, 1995Date of Patent: January 16, 1996Assignee: Axis USA, Inc.Inventors: Luciano Santandrea, Massimo Lombardi, Salvatore Amato

Patent number: 5474166Abstract: An apparatus for automatically adjusting the distance between two support members for carrying workpieces of different dimensions. The support members are mounted on guides that are fitted to pallets that travel on conveyor transport systems for automatic production/assembly lines. In one embodiment the support members have a locking device that frictionally secure the support members in place on the pallet and can be unlocked for movement along the guide. A positioning unit engages the pallet so that the locking device is unlocked and the support members are engaged and translated to the desired locations under the control of a drive. In a second embodiment the support members are translated along and under the control of a threaded bar. A positioning unit engages the pallet to activate the threaded bar by rotating it to translate the support members to the desired locations. The support members are independently translated using one threaded bar and the drive for each support member.Type: GrantFiled: August 16, 1994Date of Patent: December 12, 1995Assignee: Axis U.S.A., Inc.Inventors: Luciano Santandrea, Massimo Lombardi

Patent number: 5401531Abstract: A system for processing components which are to be transferred to second system. Portions of the system are selectively controlled so that when demand from the second system is stopped, processing of the components is allowed to be completed as needed. The system includes a preparation station which is stopped once demand is stopped, a processing station which continues to process components until such process can be safely stopped without producing unusable finished products, and a waiting station which is stopped once demand is stopped. The capacity of the waiting station is adjustable in order to accommodate components which must be passed out of the processing station so that other components may be passed through the processing station to complete all uninterruptable processes.Type: GrantFiled: July 30, 1992Date of Patent: March 28, 1995Assignee: AXIS USA, Inc.Inventors: Alessandro Faraoni, Massimo Lombardi

Patent number: 5383620Abstract: Structures which facilitate changing the shrouds which are used to guide armature coil wires into the slots in electric motor armatures during armature coil winding are shown. The shrouds may need to be changed when armatures of different sizes are to be wound. The disclosed structures provide secure mounting of the shrouds, but also allow the shrouds to be removed and replaced without the need for tools. Other elements which are needed for operating on the armature may also be removably mounted, or may be mounted on the shroud so that when the shroud is changed, these other elements are also automatically changed.Type: GrantFiled: August 9, 1993Date of Patent: January 24, 1995Assignee: Axis USA, Inc.Inventors: Massimo Lombardi, Gianluigi Pisani

Patent number: 5383619Abstract: The balance of rotors for dynamo-electric machines (e.g., electric motor armatures), which are wound with two diametrically opposite, simultaneously applied coils of wire, is improved by ensuring that wire is fed to both coils in substantially similar quantities. This can be accomplished by monitoring the consumption of each wire as it is fed to its respective coil, and adjusting the tension with which at least one wire is fed to its coil to substantially equalize the wire consumptions. Alternatively, the tension at which both wires are fed to the coils is monitored, and the tension of at least one wire is adjusted to equalize the tension of the two wires.Type: GrantFiled: April 2, 1993Date of Patent: January 24, 1995Assignee: Axis USA, Inc.Inventors: Giuseppe Cardini, Massimo Lombardi, Mauro Tarchi

Patent number: 5383618Abstract: A machine for winding two-pole stators includes a revolving table around which are located at least three working stations: a station to feed the machine with unwound stators from a conveyor placed alongside the machine and for returning the wound stators to the conveyor; a winding station where one or more winding needles with alternating translatory and angular motion wind the stator; and a terminating station with means to anchor the coil leads to the stator. The revolving table carries a plurality of circumferentially spaced stator housings, each stator housing having stator-containing means. The stator housings and table are equipped with mechanical, reciprocally meshing means, those on the table being located between the winding station and the load/unload station for rotating the stator housings about the horizontal axis tangentially to the table between a position in which the axis of the stator-containing means is vertical and a position in which that axis is horizontal.Type: GrantFiled: February 15, 1994Date of Patent: January 24, 1995Assignee: Axis S.p.A.Inventors: Luciano Santandrea, Massimo Lombardi
