A stator of an electrical machine includes a stator core having a
plurality of stator teeth and stator slots, and a stator winding having a
plurality of stator coils. The width of each stator coil is one stator
slot pitch, and the stator teeth are shaped to allow each stator coil to
be installed by pushing the stator coil to surround one of the stator
teeth. The stator coils include tubular cooling channels for conducting
cooling liquid in the stator slots.
