Abstract
A universal coil cutter for reclaiming dynamo electric machines. Specifically to cut-off the end turns of the coils of stators, rotors or armatures. The coil cutter consisting of a direct drive cutter(16), spindle and motor(15) and motor driven carriages for the x-axis(22) and the y-axis(12). The above are controlled with a joystick(10) and operate in a third plane on the z-axis(21). The table (17) is used to support the stators which are being reclaimed. Adjacent to the table(17) is a carriage with base(25) and journal (27) and rotor drive motor (23). Attached thereto a rotor drive pulley(24). The rotor belt tensioner(26) takes up slack in the drive belt which loops over and around the rotor and the drive pulley(24).
Claims3
An apparatus for cutting end turns of stator, rotor and armature windings comprising:
- a motor within a support housing, an extended shaft attached to said motor, a saw attached to said shaft, and bearings within said support housing for supporting said shaft, said support housing mounted on a y-axis motor driven carriage which is mounted on an x-axis motor driven carriage which in turn is mounted on a z-axis carriage above a table for supporting a first workpiece with said end turns in a first cutting mode, a control means which communicates with a drive motor of each of said y-axis and said x-axis motor driven carriages to move the saw in a path around the first workpiece while cutting a plurality of said windings in said first cutting mode, and rails to support a workpiece stand on said table which allows for rotary motion of a second workpiece with said end turns in a second cutting mode, and a drive belt for looping around a diameter of the second workpiece and a drive pulley for imparting said rotary motion, the control means moving said saw into the windings of said second workpiece to position said saw to cut off a plurality of said windings of said second workpiece as said second workpiece is rotated in said second cutting mode.
