Full Load Current of Motors
AC Motors – full load current tables (1500rpm approx.)
The tables are based on motors of approximately 1500rpm of average efficiency and power factor.
Motors of higher speed usually take a lower current than that shown in the table; while motors of
lower speed usually take higher current. Wide variations from these figures can arise, especially on
single phase motors, and engineers should, whenever possible, determine the actual full load current
from the motor rating plate.
