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.
Claims6
A vehicle AC generator comprising a rotor, a stator having a stator core and a stator winding, a pair of front and rear frames for supporting said rotor and said stator and electric components including a rectifier unit and other parts disposed outside said pair of frames, wherein
- said stator winding is connected to said rectifier unit by one of means of welding, soldering and clamping, and
- said rear frame has a stay having a fixing surface disposed at the rear of said electric components.
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, said rear frame having a plurality of air intake windows at a rear portion thereof;
- and
- electrical components including a rectifier unit connected to said stator winding by one of means of welding, soldering and clamping disposed at the rear of said rear frame;
- wherein
- said rear frame comprises a cylindrical outer wall and a fixing stay having forking link portions extending from said outer wall to a portion rear of said electric components and an air discharging window disposed between said forking link portions, and
- said link portion has a portion for guiding air discharged from said air discharge window so as not to return to any of said plurality of air intake windows.
