Abstract
A rotary electric machine includes a coil portion of the stator coil that protrudes from an end of a stator core, a terminal module that is provided on a top of the coil portion on an axial end of the coil portion and that electrically connects the stator coil and an external electric device, and a cover unit in which a cover that covers the terminal module and a guide that guides a coolant to the coil portion are formed together into one piece. The guide is provided on each of circumferentially opposite sides of the cover to supply a coolant to the coil portion in a distributed manner.
Claims11
A rotary electric machine comprising:
- a rotor that rotates about a shaft;
- a stator that has a stator core and a stator coil;
- a coil portion of the stator coil that protrudes from an end of the stator core;
- a terminal module that is provided on a top portion of the coil portion at an axial end of the coil portion and that electrically connects the stator coil and an external electric device;
- and
- a cover unit in which a cover that covers the terminal module and a guide that guides a coolant to the coil end are formed together into one piece, wherein the cover covers the terminal module at each of an outwardly axial side, and outwardly radial side and an inwardly radial side of the terminal module so as to electrically and mechanically protect the terminal module,
- wherein the rotary electric machine being placed such that the shaft extends generally horizontally.
