摘要： An induction motor type electric train and a control method for the same are proposed in which overcurrent to induction motors is restrained and therefore overheat of the induction motors due to overcurrent can be prevented effectively. An induction motor current command value that is a target value of output current of a power converter is generated. The power converter is controlled in such a way that the output current of the power converter follows the induction motor current command value, while a magnitude of the induction motor current command value is limited in such a way that overcurrent to the induction motors due to a wheel diameter difference between respective wheels driven by the respective induction motors is restrained, based on a rotational frequency of each induction motor.
