An air-damped engine mount has a filter module installed in a damping chamber formed by coupling between a main rubber and a main pipe. The air-damped engine mount may include a bolt, a main rubber into which the bolt is fitted and coupled, a hollow main pipe coupled with the main rubber and supporting the main rubber, a cover plate coupled with the main pipe to form a damping chamber between the cover plate and the main rubber, and a filter module coupled with the cover plate and configured to permit air to communicate through the filter module against flow resistance with the damping chamber and the outside, wherein the flow resistance against the air passing through the filter module regulates air pressure inside the damping chamber to reduce vibration in the main rubber.

A method for controlling a washing machine includes comparing a command value of a motor with a predetermined limit value, during spin-drying, to determine whether the motor is overloaded, and controlling driving of the motor in response to the determination. It may be possible to determine a water filling state, an excessive bubble state, or a drainage error state, which may be caused during a spin-drying operation, and to take a proper measure. That is, in the drainage error state, a user is informed of the drainage error. In the water filling state, the spin-drying is normally completed by re-performing the spin-drying operation. In the excessive bubble state, a rinsing or spin-drying operation is added to remove the bubbles. When the bubbles are not removed by the added rinsing or spin-drying operation, the excessive bubble message is displayed to inform a consumer of the excessive bubble state.

A pneumatic active engine mount has a middle fluid chamber and a pneumatic chamber inside an orifice module using a pneumatic plate. The orifice module divides an inner space in which working fluid is encapsulated into an upper fluid chamber and a lower fluid chamber. A change in the air pressure of the pneumatic chamber causes a change in the pressure of the middle chamber to thereby introduce a flow of working fluid between the upper fluid chamber and the middle fluid chamber. Various frequencies of vibration in an engine of a vehicle are reduced, and in particular, engine vibration in a middle-to-idling range is actively reduced.
