PURPOSE: An electric control engine mount is provided to be rapidly adapted to engine vibration changed by vehicle condition and traveling condition by forming a second orifice between a main fluid chamber and a secondary fluid chamber with a controller controlling the opening of the second orifice. CONSTITUTION: A first orifice(6) is placed between a main fluid chamber(4) and a secondary fluid chamber(5). A cover body(22) is formed in the upper end of the first orifice and a movable plate(23) is formed in the lower end of the first orifice to be a second orifice(24). An electromagnet(21) is formed on the cover body and a first movable hole(25) is communicated with the main fluid chamber in the center of the cover body. A second movable hole(26) is communicated with the secondary fluid chamber on the outer case of the movable plate. Thus, fluid flows to the secondary fluid chamber through the first and the second movable hole. In case of a large engine vibration, the electromagnet is magnetized to increase fluid resistant power and an opening plate(27) closes the first movable hole to flow fluid to the secondary fluid chamber only through the first orifice. In case of a small engine vibration, the first movable hole is opened with reduced fluid resistant power to flow fluid to the secondary fluid chamber though both orifices.
