The invention discloses a motor displacement control method of an engineering machine, electronic equipment, the engineering machine and a computer readable storage medium. The method comprises the steps that the current rotating speed of a hydraulic motor and target variable information influencing the rotating speed of the hydraulic motor are obtained; according to the target variable information, the theoretical rotating speed of the hydraulic motor is determined; and comparing the theoretical rotating speed with the current rotating speed, and adjusting the current control current of the hydraulic motor based on the obtained comparison result. Thus, the control current of the hydraulic motor is automatically adjusted according to the load condition, the overspeed and impact phenomena existing in the loading lowering process in the prior art are effectively avoided, and the safety of the engineering machinery is improved.
