Patent number: 4878292Abstract: A machine for driving and variable length cutting of the paper used in the armature of an electric motor rotor. The machine comprises a feed distance covered by the paper between shaping rollers, over which a pressure wheel is located which pushes the paper against a ledge and then slips. A paper cutting blade is inserted between the wheel and the ledge. Transfer devices located between the blade and the ledge transfer the cut paper to a bending fixture, which gives the paper the shape of the rotor slot. The paper is pushed into the rotor slot by inserting devices. The rotor is moved from the conveyor on which it is supplied to a suitable position to receive the paper. Locking elements connected to the ledge vary the length of the cut paper with respect to the height of the rotor slots where the paper is inserted.Type: GrantFiled: April 18, 1988Date of Patent: November 7, 1989Assignee: Axis S.p.A.Inventors: Luciano Santandrea, Massimo Lombardi

Patent number: 4845832Abstract: A proximity switch actuated by a press driven plunger is employed to generate a control signal at a predetermined point in the operating cycle of a high-speed stamping press when a press carried punch is at a precisely predetermined elevation above the die surface. Locating devices are provided for accurately locating the plunger at selected elevations relative to the die surface to establish an initial setting for the triggering of the proximity switch and to enable a resurfacing of the plunger concurrently with the sharpening of the die so that resetting of the proximity switch after a sharpening of the die is not required.Type: GrantFiled: May 26, 1988Date of Patent: July 11, 1989Assignee: Carbet CorporationInventors: Benson D.

Patent number: 4619028Abstract: Elongated thin strip stock is blanked to form interlocking laminas for electric motor or generator rotors or stators at successive blanking stations. At a final assembly station the laminas are stacked and pressed into interlocking relationship. In response to an operator input a predetermined number of reversals, or half turns about the stack axis of the previously stacked lamina are provided in order to compensate for nonuniform strip thickness to obtain a rotor or stator of substantially uniform height. Alternatively the thickness of the strip stock is gauged at transversely spaced points on the strip to determine cross feed thickness variation in the strip whereupon the stacked laminas are automatically provided with a number of reversals about the stack axis in response to a thickness differential that would result in a parallelism error in the stack that exceeds a predetermined amount.Type: GrantFiled: March 25, 1983Date of Patent: October 28, 1986Assignee: L H Carbide CorporationInventor: Thomas R. Neuenschwander

Patent number: 4235656Abstract: A method and apparatus for forming a coreless armature winding for an electric machine, such as a motor, having two or more poles. A source of wire is revolved in a fixed orbit about a rotatable cylinder, the axis of this orbit being inclined with respect to the longitudinal axis of the cylinder. The wire is guided about first and second guide members positioned at opposite spaced apart locations on the surface of the cylinder. These guide members define the opposite ends of the coreless armature winding such that when the wire is wound thereabout, one complete turn is formed on the surface of the cylinder. The cylinder is rotated about its longitudinal axis in synchronism with the revolution of the wire, the cylinder being rotated by a predetermined angle corresponding to the pitch of the winding so that, as the wire continues to revolve, successive skewed turns are formed on the surface of the cylinder.Type: GrantFiled: February 26, 1979Date of Patent: November 25, 1980Assignee: Sony CorporationInventors: Sachio Shimada, Akio Tsunaki, Tatsuo Furuichi, Tsuneyuki Hayashi
