Selection Tables – Three Phase Motors

AC Motors – full load current tables (1450rpm approx.)
(provided as a guide to the selection of suitable MEM control gear). The tables are based on motors of approximately 1450rpm 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 f.l.c from the motor rating plate in each case.
