A sheet metal motor mount is designed to rigidly support the motor shaft bearing (aligns motor to gears) and incorporate two bearing holding tabs. The chosen design is simple and efficient, using a minimal number of folds and material to create flanges that accommodate the pins and fasteners and tabs that hold the bearings in place. The tabs have a spring-like form to maximize their ability to withstand deflection. A pin and slot on opposite corners of the part serve to position the motor mount relative to the shaft alignment part. Two M2 SHCS screws are used to fasten the motor mount to the shaft alignment part. A vertical tab of material directly below the motor shaft bearing serves as a datum feature and maximizes the accuracy of the bearing positioning. The part is stamped from a 63mm x 83mm sheet of 16 gauge (1.651mm) steel and folded into shape.
