The invention provides a servo driver of an electric locomotive and a driving method of the electric locomotive. The servo driver comprises an inversion module, a current sensor, a processor, a pulse width modulation (PWM) module and a vector control module. The servo driver provided by the invention has the advantages of low-speed and large-torque output, large traction force, more stable operation, settable operation speed, flexible startup and shutdown and capability of greatly reducing an impact force; and an inner power circuit adopts controllable silicon rectifier technologies, so that the fault protection performance of the servo driver can be greatly improved. The traction method of the electric locomotive is characterized in that a storage battery on the electric locomotive can directly supply power, and therefore, an external power distribution device for the servo driver can be omitted; a power source voltage alarm threshold value can be set arbitrarily, so that protection for the storage battery can be benefitted. With the servo driver of the electric locomotive and the driving method of the electric locomotive of the invention adopted, when the external power distribution device is not provided, the servo driver can complete traction for the electric locomotive, and the electric locomotive can be put into and delivered out from a warehouse accurately, quickly and conveniently.
