Abstract:
A cap in combination with a series loop of a bar wound armature of an electrical system, the cap comprising:first and second cap sections, each of said cap sections having (i) first and second opposed generally parallel longitudinally extending side walls, (ii) an end wall extending generally between said side walls adjacent one end of said cap section and (iii) a cover extending between said side walls and from said end wall along said cap section leaving free edges of said side and end walls remote from said cover;said first and second cap sections being assembled to form the cap with the first and second side walls of said first cap section disposed adjacent the second and first side walls of said second cap section, respectively, (ii) the end wall of said first cap section disposed adjacent the end wall of said second cap section, and (iii) the covers of said first and second cap sections spaced one from the other whereby said covers, said side walls and said end walls of said first and second cap sections together define an enclosure open at an end thereof opposite said end walls for receiving the series loop of the bar wound armature;said first and second side walls of at least one of said cap sections having a cutout defined therein so that when said first and second cap sections are assembled said cutouts of said side walls define first and second ventilation openings in the cap, andwherein said series loop includes first and second conductor bars, said first conductor bar extending generally between said side walls of said first cap section and said second conductor bar extending generally between said side walls of said second cap section, at least one of said conductor bars defining at least one gas passage therealong whereby at least one cooling air flow path is defined through said cap substantially from said one ventilation opening to the other along said gas passage defined by said conductor bar.
