Plotting Grouped Motor Curve
When plotting the starting curve for grouped motors, you need to specify the largest motor size in addition to other data required for individual motors. The plot assumes that the largest motor is starting and the rest of the motors are already operating at steady state. The current in the plot is calculated as follows:
During Acceleration:
Total Amps = Locked rotor amps of largest motor + FLA of the rest
After Acceleration:
Total Amps = Total FLA of all the motor
