Abstract
A stator system for an electric vehicle motor may include a stator forming a back iron and a plurality of teeth extending inwardly therefrom, the stator including a plurality of attachment points protruding radially outwardly from the back iron, and a case configured to house the stator and defining a plurality of case openings, each configured to receive one of the attachment points, wherein each attachment point defines at least one T-slot configured to receive a nut that cooperates with a bolt extending through the case to connect the case to the stator.
Claims14
A stator system for an electric vehicle motor, comprising:
- a stator forming a back iron and a plurality of teeth extending inwardly therefrom, the stator including a plurality of attachment points protruding radially outwardly from the back iron;
- and
- a case configured to house the stator and defining a plurality of case openings, each configured to receive one of the attachment points, wherein each attachment point defines at least one T-slot having a proximal portion and a distal portion, the proximal portion having a larger dimension than the distal portion and configured to receive a nut that cooperates with a bolt extending through the case to connect the case to the stator.
A stator system for an electric vehicle, comprising:
- a stator forming a back iron and a plurality of teeth extending inwardly therefrom,
- at least one attachment point protruding radially outwardly from the back iron and configured to engage with a case;
- the attachment point defining at least one slot configured to receive a nut that cooperates with a bolt to connect the case to the stator, wherein the at least one slot is a T-slot having a proximal portion and a distal portion, the proximal portion having a larger dimension than the distal portion.
A stator attachment mechanism, comprising:
- at least one bolt ear protruding radially outwardly from a back iron of a stator and configured to engage with a case, the bolt ear defining at least one T-slot configured to maintain a nut in a proximal portion of the T-slot, the nut configured to receive a bolt extending through the case and through a distal portion of the T-slot wherein the bolt tightens to the nut to fix the case to the stator.
