ElectrotorSimplex_PowerTrain

Electrotor-Simplex ~ Power Train

Ratios, HP, Torque & Losses:

Torque: [ft-lb] = 5252 * HP / RPM

Input: 5252 * 20 /6000 = 17.5 lb-ft
Output: 5252 * 20 / (6000/12) = 210 lb-ft
This means that the force on one pitch-link, if it is at 1 ft. radius will be 105 lbs. Or. At 15 hp it will be 76 lbs.
Note that the electric motor will not generate shock loading, but, a motor can produce high torque for a short period of time. However this high torque should never exceed the 20 HP.

Nominal output torque at output shaft NEMA 34, 12:1; 120 N-m = 88.8 lb-ft. I think that this is the planetary 2-stage reducer.
