A rotating element control system includes a rotating element rotatably disposed on a main body, a first sensing unit which senses a rotational speed of the main body, a driving unit which drives the rotating element, a second sensing unit which senses a rotational speed of the rotating element, a torque compensation unit which generates a first compensation signal within a first range and a second compensation signal within a second range, and a stabilization control unit which controls the driving unit based on the first and second compensation signals and a difference between a speed of a command to drive the rotating element and the rotational speed of the rotating element.

Control System for rotating shaft

A rotating element control system includes a rotating element rotatably disposed on a main body, a first measuring unit which measures an angular movement of the main body, a driving unit which drives the rotating element, a second measuring unit which measures a rotational speed of the rotating element, a transfer unit which connects the rotating element and the driving unit and transfers a driving force to the rotating element, a motion compensation unit which generates a compensation signal which removes an error component generated by the angular movement of the main body, and a stabilization control unit which controls the driving unit based on the compensation signal and a difference between an input signal and the rotational speed of the rotating element.

Control system for rotating shaft

An ice making apparatus is provided. A fluid passage guide is formed in the water supply unit to prevent water discharged from the water supply unit from being splashed to an external side of the tray.

Ice making apparatus

The present invention discloses a refrigerator with a water tank for supplying water to an ice tray by closing of a door. A refrigerator includes a cooling chamber for storing an article at a low temperature, an ice tray positioned in the cooling chamber and filled with water, for making ice, a water tank with a water supply hole for storing water and supplying water to the ice tray, and a valve for selectively opening and closing the water supply hole. In addition, a refrigerator includes a cooling chamber for storing an article at a low temperature, a main body for defining the cooling chamber, a door for opening and closing the cooling chamber, an ice tray positioned inside the door and filled with water, for making ice, a water tank with a water supply hole for storing water and supplying water to the ice tray, and a valve for selectively opening and closing the water supply hole.

Refrigerator

The present invention relates to a door duct assembly for a refrigerator. In the present invention, the cold air delivered from a cold air duct of a refrigerator main body to a doorthrough a cold air communication portionis discharged into a storage space through cold air ventsformed in a flow guide. The cold air communication portionis formed in a door basketor the flow guide. The door basketsor the flow guideis mounted on a door linerdefining a rear surface of the door. According to the present invention, there are advantages in that it is relatively easy to manufacture a door, the cold air flows uniformly in the door, the strength of the flow guide for defining a flow channel in the door is relatively increased, and dewdrops are prevented from being formed upstream of the flow channel.
