Abstract
A vehicle AC generator includes a rotor, a stator having a stator core and a stator winding, a pair of front and rear frames and electric components including a rectifier unit and other electrical parts disposed rear of the rear frame. The stator winding is connected to the rectifier unit by one of means of welding, soldering and clamping, and the rear frame has a stay having a fixing surface disposed rear of the electric components. Therefore, it is not necessary to provide a space for screwing a screw bolt to connect the stator winding and the rectifier unit. Because cooling air is discharged from a discharge window along the stay, heated air will not return to any of air intake window.
Claims5
A vehicle AC generator comprising:
- a rotor having a cooling fan at a rear end thereof;
- a stator having a stator core and a stator winding;
- a pair of front and rear frames for supporting said rotor and said stator;
- electrical components including a rectifier unit connected to said stator winding disposed at the rear of said rear frame;
- and
- a rear cover for covering said electrical components, said rear cover having at least one air intake window disposed at a rear of said electrical components;
- wherein
- said rear frame comprises a cylindrical outer wall and a fixing stay having forking link portions extending from said outer in front of said electrical components to a portion around said rear cover at the rear of said electrical components, said outer wall having an air discharging window disposed between said forking link portions of said fixing stay, and
- said fixing stay comprises a surface at a portion around said air discharging window for guiding air discharged from said air discharging window radially outside said rear cover.
