A test system predicts when brush holder support blocks in a traction motor frame commutator chamber are properly oriented with respect to each other and a bore axis. Brush holders are modified to include a rod extending orthogonally therefrom. First and second rods extending from opposite sides of the commutator chamber are substantially parallel, and third and fourth rods extending from opposite sides of the commutator chamber are also substantially parallel. The four rods form a rectangle-like polygon having first and second opposed sides and third and fourth opposed sides. In accordance with the testing method, the lengths of the sides, the difference between the lengths of the first and second opposed sides, and the difference between the lengths of the third and fourth opposed sides provide an indication of the orthogonality and spacing of the brush holder support blocks with respect to the bore axis.

[ I claim:] [1.] A method of predicting when first, second, third and fourth brush holder support blocks of a motor having a bore axis are properly positioned with respect to the bore axis, the method comprising the steps of:providing first and second substantially parallel rods positioned with respect to the first and second brush holder support blocks of the motor, third and fourth substantially parallel rods positioned with respect to the third and fourth brush holder support blocks of the motor, such that the first, second, third and fourth rods form a rectangle-like polygon including first and second opposed sides and third and fourth opposed sides;determining the lengths of the first, second, third, and fourth opposed sides;determining a first difference comprising a difference of the lengths of the first and second opposed sides;determining a second difference comprising a difference of the lengths of the third and fourth opposed sides; andusing the lengths of the first, second, third, and fourth opposed sides and the first and second differences to provide an indication of the orthogonality and spacing of the first, second, third and fourth brush holder support blocks with respect to the bore axis. [5.] A test system for determining the proper positioning of brush holder support blocks on a motor having a bore axis comprising:a motor including a frame having a commutator chamber;first, second, third and fourth brush holder support blocks situated about the commutator chamber;first, second, third and fourth brush holders mechanically coupled to the first, second, third and fourth brush holder support blocks, respectively; andfirst, second, third and fourth rods extending orthogonally from the first, second, third and fourth brush holders, the first and second rods being oriented substantially parallel to each other, the third and fourth rods being oriented substantially parallel to each other, such that the first, second, third and fourth rods form a rectangle-like polygon including first and second opposed sides and third and fourth opposed sides, so that the lengths of the first, second, third, and fourth opposed sides, as well as the difference in length of the first and opposed second sides and the difference in length of the third and fourth opposed sides can be used to provide an indication of the orthogonality and spacing of the first, second, third and fourth brush holder support blocks with respect to the bore axis.
