About this file
This is an engineering drawing for a Motor Magnet (Part No. A1-67377, Revision 0) produced by Tobyhanna Army Depot, Department of the United States Army. The drawing specifies a neodymium magnet constructed from N42H material grade with a maximum energy product (BHmax) greater than 40-42 MGoe and a magnetic field strength of 2,400 Gauss measured at the surface. The magnet-to-magnet pull force is specified at 0.39 pounds. Dimensional tolerances are provided with fractions at ±2 places (0.03), decimals at ±3 places (0.005), and angles at ±1 degree. Key dimensions include 0.581 inches (±0.005), 0.063 inches (±0.003), and 0.209 inches (±0.005), with the magnet oriented to identify north-facing and south-facing sides.
Quality and finish requirements mandate that suppliers submit a quality control plan as part of the first article sample package, including recorded measurements of all dimensions shown on the part drawing. The magnet requires a nickel coating 10 microns thick as finish. Packaging requirements specify that parts be packaged to prevent damage during shipment and marked with part number, revision level, and quantity. The drawing notation clarifies that data marked with an asterisk is peculiar to a prior manufacturer and does not take precedence over other drawing data nor is it contractually binding on either the contractor or the government. This document has been purchased by the government and may be reproduced in connection with any government procurement or maintenance operation.
