The present invention relates to the technical field of molten iron transport in the metallurgical industry. Disclosed are a permanent magnet direct-drive torpedo ladle car and a control method therefor. The permanent magnet direct- drive torpedo ladle car comprises: a front-end traveling device directly driven by a permanent magnet motor; a rear-end traveling device which has the same structure as the front-end traveling device and is directly driven by the permanent magnet motor; and a dump mechanism and a torpedo ladle body which are located between the front- end traveling device and the rear-end traveling device. A first traction transmission system is provided in the front- end traveling device; a second traction transmission system is provided in the rear-end traveling device; a first car control device in the first traction transmission system is a main control device of the torpedo ladle car; a second car control device in the second traction transmission system is an auxiliary control device of the torpedo ladle car; the main control device and the auxiliary control device are interconnected and controlled by means of a wireless reconnection module. According to the present invention, without changing the main structure of an existing torpedo ladle car, self-propelled travelling of the torpedo ladle car directly driven by a permanent magnet motor and a "one ladle from BF to BOF" transport mode are achieved, and the turnover rate and utilization efficiency of torpedo ladle cars can be greatly improved.
