Armature Inspection/Balancing

 

Looking to build a race car using a factory Aurora, Dash, or AutoWorld armature?  Send me your favorite Factory Stock Armatures and I will perform the following services for you to maximize the performance of your motor:

 

  • Visual Inspection: I visually inspect the armature for any obvious flaws that would impede it's performance.
  • Electrical Checks: Measure for uniform resistance (ohms) across all armature poles and test for electrical shorts.
  • Shaft Inspection/Polishing: Measure the shaft for straightness, adjust if necessary, and polish it.
  • Commutator Plate Truing: Measure the commutator plate for perpendicularity (run-out) to the shaft, adjust if necessary, and polish it.
  • Stack Truing: True the pole faces (stacks) for concentricity to the shaft, and even air gaps between magnets. (Note: this is done on a lathe for precision turning, not a Dremel Tool.
  • Epoxy Balancing: Balance the armature with Epoxy (if a gross out of balance condition exists).
  • Material Removal Balancing: for armatures with a slight out of balance condition.
