Just somewhere I can publically share derived motor values.

Common US-Domestic Motor Resistances

  • WEMCO 362: 0.0366
  • WEMCO 370: 0.01941
  • GE 752: 0.02149
  • GE 761: 0.04749
  • EMD D37: (0.01446 0.00975 0.00751) = 0.03172
  • EMD D47/57/67/75: (0.0144 0.00876 0.00652) = 0.02968
  • EMD D77: (0.01232 0.00876 0.00652) = 0.0276
  • EMD D87: (0.01190 0.00797 0.00635) = 0.02622

Common US-Domestic Motor Torque Factors

(Can be experimentally derived with a known Gear Ratio, Continuous Force, Continuous Amperage and Wheel Size) Example: EMD GP30 - 980 Amps continuous - 50,000lbs continuous on 62:15 (or 4.133) gearing on 40" (20" radius) wheels. Four axles, so 12,500lbf per axle at 1.666 ft away from wheel hub. Torque at Armature = (12500 * 1.666) / 4.1333 = 5038 ftlbs. 5038 / 980 = ~5.15 ftlbs per amp

  • EMD D57 (e.g. GP30): 5.15
  • GE 752E5, AF (e.g. road alco): 5.127

(i'll add more as I can)
