Abstract :
MW-1000 is being expanded to include three magnet wires being used in hermetic motor applications. This paper will review the steps taken to develop the Refrigerant Extraction Test-Residue Method and the procedure for determining the Retained Dielectric Breakdown Level After Conditioning in Refrigerant 22. These two test procedures will help characterize two essential qualities to be controlled in this hermetic industry. Proposed standards, MW 71-C-“Aromatic Polyimide-Coated Round Copper Magnet Wire for Hermetic Motor Applications (Heavy)”, MW 72-C-“Polyesterimide or Polyesteramide-Imide Coated Round Copper Magnet Wire for Hermetic Motor Applications (Heavy)”, MW 73-C-“Modified Polyester or Polyesterimide or Poolyesteramide-Imide Overcoated with Polyamide-Imide Round Copper Magnet Wire For Hermetic Motor Applications (Heavy)”, will be discussed in terms of the high quality guidelines requested by hermetic motor and compressor manufacturers.
