Abstract: A refrigerator includes: an ice maker for generating ice; an ice bin for storing the ice and including a rotational blade that is rotated in order to discharge the ice; a motor for generating power for rotating the rotational blade; a manipulation pad provided on the door of the refrigerator and manipulated to discharge the ice from the ice bin; a manipulation sensing part for detecting the manipulation of the manipulation pad; and a controller for operating the motor when the manipulation of the manipulation pad is detected by the manipulation sensing part, wherein the controller rotates the motor in one direction to discharge the ice from the ice bin and the controller rotates the motor in the other direction, which is the opposite direction of the one direction, for a set period of time when the manipulation of the manipulation pad is no longer detected.

Abstract: A motor assembly includes a brushless direct current (BLDC) motor; a gear box in which the BLDC motor is installed; and a power transmission part having a plurality of gears installed in the gear box so as to transmit power generated by the BLDC motor to an ice bin. The BLDC motor comprises: a stator and a rotor rotating with respect to the stator, wherein the rotor may be connected to the power transmission part by a shaft and the stator may be coupled to the gear box in a separable manner.
