A 460V,3-phi ,20-hp, 1800RPM, squirrel-cage induction motor is fed by a 20A feeder circuit
and is mechanically coupled via a drive belt to a conveyor system.
(a) Determine the approximate full-load current that the motor requires.
(b) A foreign object lodges in the conveyor system and seizes the conveyor. Name the
condition under which the motor is currently being operated.
(c) Determine the approximate motor current under the condition of part (b).
(d) The abuse sustained in part (b) has subsequently caused the drive belt to break. De-
termine the approximate motor current now.
(e) Comment on the suitability of the feeder circuit supplying the motor in the above sce-
nario.
