Motor holder

This part is formed using an automatic stamping die with a 90° right-angle bend joining two planes, requiring high bend-angle precision (controlling the Ø38 perpendicularity within 0.2 and 21.7±0.2) so the motor mounts in the correct position without shaft misalignment during operation.

The Ø38 motor-mounting hole must maintain roundness and positional accuracy relative to the two surrounding locating holes, since even slight deviation affects motor shaft concentricity.

The 2.3mm-thick material provides the rigidity needed to withstand the motor’s load and vibration during sewing machine operation, but this also requires strong, stable press force to form the precise bend without cracking or deforming the material.
