Abstract
A cutting device for cutting a wedge and/or conductive bar or coils and/or part of thereof within a slot of an electric machine includes a saw with at least a blade, a guide for guiding the saw during cutting, the guide being connectable to the electric machine. The saw and the guide are withheld together preventing their separation.
Claims13
Cutting device for cutting a wedge and/or conductive bar or coil within a first slot in a stator core or rotor core of at least one of a stator and a rotor of an electric machine, the device comprising:
- a saw with at least one blade having a cutting axis;
- a guide for guiding the saw during cutting, the guide being connectable to the electric machine, the saw and the guide are held together preventing their separation, wherein the guide includes:
- a first slide configured to be slidably housed within a second slot in the stator core or rotor core;
- and
- a second slide at an opposite position of the saw with respect to the first slide, and configured to be slidably housed within a third slot in the stator core or rotor core, wherein the first slide and the second slide are arranged on opposite sides of the at least one blade and configured to slide along parallel axes and the first and second slides are dovetail shaped and configured to engage respective recessed sides of the second and third slots.
Cutting device for cutting a wedge and/or conductive bar or coil within a first slot in a stator core or rotor core of at least one of a stator and a rotor of the electric machine, the device comprising:
- a saw with at least one blade having a cutting axis;
- a guide for guiding the saw during cutting, the guide being connectable to the electric machine, the saw and the guide are held together preventing their separation, wherein the guide includes:
- a first slide configured to be slidably housed within a second slot in the stator core or rotor core;
- and
- a second slide at an opposite position of the saw with respect to the first slide, and configured to be slidably housed within a third slot in the stator core or rotor core, wherein the first slide and the second slide are dovetail shaped and configured to engage respective recessed sides of the second and third slots,
- a frame with connecting elements for connecting the frame to the electric machine, the frame being curved in a direction perpendicular to the cutting axis of the blade, the curve corresponding to a stator core or rotor core inside curvature, and
- a guide bar arranged on the frame parallel to the cutting axis, the saw being slidably connected to the guide bar for cutting the wedge and/or conductive bar or coil in the first slot by the at least one blade.
