Patent number: 6364277Abstract: An armature assembly support pallet has armature assembly support surfaces which exhibit a magnetic field that magnetizes the portions of the armature shaft adjacent the support surfaces so that armature assembly is magnetically attracted to the support surfaces and thereby maintained in a precise axial position on the pallet as the pallet is conveyed between work stations. The magnetic field is preferably created by thin layers of magnetic material secured to upwardly-facing surfaces of V-shaped portions of support members or blocks affixed to the body of the pallet. The pallets may be used without changes or adjustments for supporting armature assemblies having a substantial range of various different configurations. Pallets of known construction, including those with adjustable support members, may be modified or retrofitted by providing them with magnetic support surfaces.Type: GrantFiled: September 15, 1995Date of Patent: April 2, 2002Assignee: Globe Products Inc.Inventor: Danny L.

Patent number: 6108897Abstract: A stator coil finish wire is wedged between the wound coil from which it extends and the stator core at a stator winding station. To accomplish this, a loop is formed in the finish lead and trapped between cooperating surfaces to frictionally resist the wire loop being pulled out by the wire gripper of a lead pull assembly. The wire gripper moves in directions to remove the loop and to wedge the stretch of the lead wire extending through the stator core between the coil and the core. This procedure is advantageously used when winding stators which do not have terminal boards.Type: GrantFiled: September 18, 1998Date of Patent: August 29, 2000Assignee: Globe Products Inc.Inventors: John M.

Patent number: 6056845Abstract: High speed bonding of wound electric components, and particularly armatures, having coils wound from bondable wire is obtained by providing a component support table having equally-spaced component-receiving stations and repeatedly indexing the table in a predetermined direction through predetermined increments. Plural wound and unbonded electric components are loaded in plural, mutually-adjacent stations on the table. After loading a first predetermined number of wound electric components, and while continuing to index the support table, an electric current is applied to the coils thereof to cause the coils of the first set of components to be heated and bonded while a second set of components is being loaded into successive stations. The application of electric current is accomplished by the use of a bonding head plate that is movable toward and away from the support table and rotates with the support table while electric current is supplied to the coils being bonded.Type: GrantFiled: September 17, 1998Date of Patent: May 2, 2000Assignee: Globe Products Inc.Inventor: Rossen A.

Patent number: 5867892Abstract: An armature shaft having an eccentric cam body extending from one end thereof is gripped by an adjustable collet mechanism and rotated by a drive motor, preferably a stepping motor, having an output shaft movable in discrete increments. This rotation continues until an imaginary reference point on the periphery of the cam body reaches first and second angular positions. The preferred reference point is the point on the periphery of the end face of the cam body that is farthest from the axis of rotation of the armature shaft. The number of steps necessary to rotate the armature shaft so that the reference point is moved from the first angular position to the second angular position is determined as the armature shaft is rotated and used to determine the position of the reference point relative to a centerline between the first and second angular positions.Type: GrantFiled: February 6, 1997Date of Patent: February 9, 1999Assignee: Globe Products Inc.Inventors: John M.
