Rotor having slanted angle side surface and laminations made therewith

A product, comprising:

• a vehicle having a plurality of rotor disks, each rotor disk having a central body portion and having a through hole formed therein, and a plurality of spaced apart teeth extending radially from the central body portion, wherein each tooth of the plurality of teeth includes an elongated stem portion having a first end at the central body portion, and wherein the elongated stem portion extends radially to a second end terminating at a transverse portion, the transverse portion having a general arch shape and extending in a first direction from a first side edge of the stem portion and extending in an opposite second direction from a second side edge of the stem portion, a first end of the transverse portion having a first side face that is not formed at a 90-degree angle with respect to a top face or a bottom face of the rotor disk and a second end of the transverse portion having a second side face that is not formed at a 90-degree angle with respect to the top face or the bottom face, transverse portions of adjacent teeth forming a gap therebetween, wherein rotor disc of the plurality of rotor disks are stacked on top of each with adjacent rotor disks being rotated with respect to each other so the gap between transverse portions of adjacent teeth on each disk is aligned with the gap between transverse portions of adjacent teeth on a respective adjacent rotor disk to form a skewed channel running a longitudinal length of the plurality of rotor disks.

A method comprising:

• providing a rotor disk having a central body portion and having a through hole formed therein, and a plurality of spaced apart teeth extending radially from the central body portion, wherein each tooth of the plurality of teeth includes an elongated stem portion has a first end at the central body portion, and wherein the elongated stem portion extends radially to a second end terminating at a transverse portion, the transverse portion has a general arch shape and extending in a first direction from a first side edge of the stem portion and extending in an opposite second direction from a second side edge of the stem portion, a first end of the transverse portion having a first side face that is formed at a 90-degree angle with respect to a top face or a bottom face of the rotor disk and a second end of the transverse portion having a second side face that is formed at a 90-degree angle with respect to the top face or the bottom face, transverse portions of adjacent teeth forming a gap therebetween;
• trimming the first side face of the transverse portion so that a trimmed first side face forms an angle with the top face or bottom face that is not 90 degrees;
• and
• trimming the second side face of the transverse portion so that the trimmed second side face forms an angle with the top face or bottom face that is not 90 degrees.
