1. A stator for an electric motor, the stator comprising:
a stator body;
a first substrate comprising a first plurality of entry slots having a height extending from a radially inner side of the first substrate facing a rotor and a first plurality of exit slots having a height extending from the radially inner side of the first substrate, the height of each of the first plurality of exit slots being greater than the height of each of the first plurality of entry slots; and
a second substrate comprising a second plurality of entry slots having a height extending from a radially inner side of the second substrate facing the rotor and a second plurality of exit slots having a height extending from the radially inner side of the second substrate, the height of each of the second plurality of exit slots being greater than the height of each of the second plurality of entry slots,
wherein each of the first plurality of entry slots forms a first channel that extends longitudinally across the stator body to a respective one of the second plurality of exit slots for distributing a fluid through the first channel in a first direction, and
wherein each of the second plurality of entry slots forms a second channel that extends longitudinally across the stator body to a respective one of the first plurality of exit slots for distributing the fluid through the second channel in a second direction different from the first direction.
