Stator assembly

A stator assembly, comprising:

• a circumferential stator core including:
• a plurality of stator poles having a length and a width;
• a plurality of stator slots, each stator slot being located between a respective pair of adjacent stator poles and extending the length of the stator poles;
• a plurality of conductive coils, each conductive coil surrounding a portion of a respective stator pole;
• and
• a coolant wall assembly extending between a pair of adjacent stator poles at a radially inner end of each stator pole, the coolant wall assembly including:
• a unitary, radially inner wall extending the length of the pair of adjacent stator poles and interlocking between the pair of adjacent stator poles on opposing sides of an individual stator slot;
• a radially outer insert positioned between the pair of adjacent stator poles and extending the length of adjacent stator poles;
• and
• at least one sealing member, wherein the at least one sealing member is positioned radially between the radially outer insert and at least one of the plurality of conductive coils.

A method for installing a coolant wall assembly within a circumferential stator core, the stator core including a plurality of radially inwardly extending stator poles;

• a plurality of stator slots located between adjacent stator poles and extending a length of the stator poles;
• a plurality of conductive coils, each conductive coil surrounding a portion of a respective stator pole;
• and the coolant wall assembly extending between radially inner ends of adjacent stator poles, wherein the coolant wall assembly includes a radially outer insert, a unitary, radially inner wall, and a pair of sealing members, each extending the length of the adjacent stator poles, the method comprising:
• inserting the radially outer insert into an individual stator slot, such that an individual sealing member of the pair of sealing members is positioned between an individual conductive coil on each adjacent stator pole and a radially outer surface receiving portion of the radially outer insert;
• compressing the pair of sealing members radially outwardly within the stator slot by applying a radially outward force to the radially outer insert;
• and
• inserting the radially inner wall within a recessed groove of each of the adjacent stator poles to secure the coolant wall assembly.
