A motor driving apparatus incudes a driving circuit outputting a three-phase alternating current and a main controller, wherein the driving circuit comprises a U-phase electric driving circuit, a V-phase electric driving circuit, and a W-phase electric driving circuit, each of the electric driving circuits comprises n storage batteries and n corresponding electric driving, and wherein input ends of the n electric driving units are connected to the corresponding storage batteries and output ends of the n electric driving units are cascaded to output one phase of the three-phase alternating current. The main controller is connected to signal ends of the n electric driving units and determines an output voltage adjustment coefficient of each of the n electric driving units in the electric driving circuit based on voltages of the n storage batteries in the electric driving circuit, and outputs the output voltage adjustment coefficient to the corresponding electric driving unit.
