Stator for drive motor

A stator for a drive motor, the stator comprising:

• a segmented stator core comprising a plurality of mounting portions;
• a bobbin equipped on each mounting portion of the plurality of the mounting portions and having a coil wound thereon;
• a casing including:
• a first casing and a second casing coupled to the bobbin at opposite sides, respectively, of the bobbin with respect to the segmented stator core, and configured to enclose the coil, wherein the casing includes a guide protrusion extending in a circumferential direction of the casing and protruding from an inner surface of the casing;
• a passage formed in the first casing and configured to fluidly communicate with an inside of the first casing and the second casing, wherein cooling oil flows in and out of the first casing through the passage;
• and
• a terminal portion integrally formed in the second casing and configured to allow connection of the coil,
• wherein the bobbin comprises a protrusion protruding outward at opposite sides of the segmented stator core and coupled to the casing,
• wherein the protrusion comprises:
• an upper protrusion protruding at a position close to an outermost side in a radial direction of the segmented stator core;
• and
• a lower protrusion arranged radially inward from the upper protrusion, and
• wherein a guide groove is recessed from a top surface of the upper protrusion and configured to mesh with the guide protrusion, and the upper protrusion is positioned inside the casing while mating with the inner surface of the casing.
