Our client:

Our Client is a manufacturer of after-market Parts for Rotating Electrical products such as Starters, Alternators, Generators, Compressors and accessories in North America.

Scope:

Reverse Engineering of Starter Motor has the following activities:

  • Measuring & Scanning of all parts/assemblies using CMM/3D Scanner
  • Creation of 3D parametric models & 2D drawings.
  • Surface Finish measurement at bearing seating areas.
  • Testing of Spring rating.
  • Creating Electrical Schematics.
  • Identifying Armature, Solenoid and Coil resistance
 

Why APA? 

APA has a dedicated team to work on Reverse Engineering of Components with an exclusive lab set up for Probing, Scanning (3D Non-Contact), and measuring dimensions of various automotive and non-automotive components. We also have the capability to identify the chemical and mechanical properties of materials.

Motor Reverse Engineering Process: 

SCANNING:

  • Prepare part by spraying white powder.
  • Fix the part properly to scan.
  • Get symmetry profile measurements before scanning the part.

PREPROCESSING:

  • Cleanup of Noise in the scan data.
  • Align to coordinate system.
  • Export as .stl format

PARAMETRIC MODELING:

  • Import .stl file.
  • Extracted curvature profiles,Generate outer surface as per ASTM A963/A963M97standards.
  • Build parametric model from scan data.

Quality Check:

  • Overlay scanned data and 3D model.
  • Identify deviations.
  • Generate comparison report

ELECTRICAL SCHEMATICS & SPRING RATING:

  • Measuring Armature, Solenoid and coil resistance.
  • Generate schematics for Armature & Solenoid with winding information.
  • Testing of Spring ratings.
  • Generate drawing for Springs.

2D DRAWING:

  • Generate 2D drwaing from 3D models.
  • Do stack up analysis and provide tolerance.
  • Surface Finish measurement at bearing seating areas.
  • Prepare Bill of Material.

Value delivered:

  • APA delivered “1 stop solution” for extracting both mechanical, electrical design informations of the Starter Motor at much lower cost when compared to onshore execution
