Electric motor coolant frame and header

An electric motor comprising a housing and a cooling frame, the cooling frame comprising:

• a stator;
• a plurality of external fluid conduits positioned in contact with the stator, the plurality of external fluid conduits configured to carry a fluid and facilitate an exchange of heat between the fluid and the stator;
• and
• a first header comprising:
• at least one header port for exchanging fluid into or out from the header;
• a first plate comprising a central opening;
• a plurality of conduit ports on the first plate positioned around the central opening and radially distanced beyond the external side of the stator, wherein each conduit port is fluidly connectable to a respective external fluid conduit of the plurality of external fluid conduits;
• a first channel fluidly connecting the at least one header port and a first conduit port of the plurality of conduit ports;
• and
• a second channel fluidly connecting a second conduit port and the at least one header port.

A method for cooling an electric motor, the method comprising:

• directing a fluid into at least one header port;
• directing the fluid through a first channel fluidly connected to the at least one header port and a first conduit port;
• exchanging heat between the fluid and the electric motor while directing the fluid through a stator of the electric motor through the first external fluid conduit and a second external fluid conduit;
• directing the fluid through a second channel fluidly connected to a second conduit port and the at least one header port;
• and
• directing the fluid out of the at least one header port.
