Maximum Power Output from Driving Axle Solution

STEP 0: Pre-Calculation Summary

Formula Used

Maximum Output Power = (Tractive Effort*Crest Speed)/3600
P_max = (F_t*V_m)/3600
This formula uses 3 Variables

Variables Used

Maximum Output Power - (Measured in Watt) - The maximum output power = the maximum output current × the rated output voltage so there is no problem if it is confirmed that one of them is not exceeded.
Tractive Effort - (Measured in Newton) - Tractive Effort, the term tractive force can either refer to the total traction a vehicle exerts on a surface, or the amount of the total traction that is parallel to the direction of motion.
Crest Speed - (Measured in Kilometer per Hour) - Crest Speed is the maximum speed attained by the train during the run.

STEP 1: Convert Input(s) to Base Unit

Tractive Effort: 545 Newton --> 545 Newton No Conversion Required
Crest Speed: 98.35 Kilometer per Hour --> 98.35 Kilometer per Hour No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_max = (F_t*V_m)/3600 --> (545*98.35)/3600

Evaluating ... ...

P_max = 14.8890972222222

STEP 3: Convert Result to Output's Unit

14.8890972222222 Watt --> No Conversion Required

FINAL ANSWER

14.8890972222222 ≈ 14.8891 Watt <-- Maximum Output Power
