Member Function Documentation

calculate() [1/3]

MotorShaftPower::Output MotorShaftPower::calculate

(

)

Calculate motor shaft power

Returns

MotorShaftPower::Output, class containing all the results of the MotorShaftPower calculations, see Output class for more details

Adjust powerFactor based on specified FLA This does not happen in the Excel sheet during the final calculations. powerFactor = powerFactor / (fullLoadAmps_/estimatedFLA);

Output in hp

Electric power is same as Field value when load estimation method is POWER

When the load estimation method is Current.

Dropping load fraction by 0.01

Adjust powerFactor based on specified FLA

Adjust current

Output in hp
