An induction motor type electric train comprising: a power converter which converts electric power acquired from an overhead power line to three-phase AC power with variable voltage and variable frequency; plural induction motors which are supplied with electricity from the power converter and drive different wheels from each other, the electricity from the power converter being supplied on a supply line which branches into respective sub-lines for onward supply of the electricity to the induction motors; a current detector which detects a current value of output current (I ο) of the power converter on the supply line before it branches into the sub-lines; plural speed detectors which are provided corresponding to each of the plural induction motors and detect rotational frequencies of the corresponding induction motors; and a power converter control unit which generates an induction motor current command value (I p) that is a target value of the output current of the power converter, and controls the power converter in such a way that the output current of the power converter follows the induction motor current command value, using the output current of the power converter detected by the current detector and the rotational frequency (f r1, f r2) detected by each of the speed detectors; wherein the power converter control unit limits a magnitude of the induction motor current command value so as to restrain overcurrent to the induction motors due to a wheel diameter difference between the wheels driven by each of the induction motors, based on the rotational frequency detected by each of the speed detectors; and wherein the power converter control unit limits a magnitude of the induction motor current command value in such a way that a value the current flowing to the induction motor having a largest absolute value of slip frequency, based on the rotational frequency detected by each of the speed detectors, becomes equal to or smaller than a value of what the current flowing to the induction motor would be when there is no wheel diameter difference. a power converter which converts electric power acquired from an overhead power line to three-phase AC power with variable voltage and variable frequency; plural induction motors which are supplied with electricity from the power converter and drive different wheels from each other, the electricity from the power converter being supplied on a supply line which branches into respective sub-lines for onward supply of the electricity to the induction motors; a current detector which detects a current value of output current (I ο) of the power converter on the supply line before it branches into the sub-lines; plural speed detectors which are provided corresponding to each of the plural induction motors and detect rotational frequencies of the corresponding induction motors; and a power converter control unit which generates an induction motor current command value (I p) that is a target value of the output current of the power converter, and controls the power converter in such a way that the output current of the power converter follows the induction motor current command value, using the output current of the power converter detected by the current detector and the rotational frequency (f r1, f r2) detected by each of the speed detectors; wherein the power converter control unit limits a magnitude of the induction motor current command value so as to restrain overcurrent to the induction motors due to a wheel diameter difference between the wheels driven by each of the induction motors, based on the rotational frequency detected by each of the speed detectors; and wherein the power converter control unit limits a magnitude of the induction motor current command value in such a way that a value the current flowing to the induction motor having a largest absolute value of slip frequency, based on the rotational frequency detected by each of the speed detectors, becomes equal to or smaller than a value of what the current flowing to the induction motor would be when there is no wheel diameter difference.
