Abstract: Provided is an electronic device. The electronic device includes a motor, a memory configured to store at least one of first frequency information associated with a sound that is generated when the motor is driven or second frequency information associated with a surrounding environment of the electronic device, and a processor configured to control the motor to be driven by avoiding a driving speed corresponding to the frequency information stored in the memory.

Abstract: A washing machine may include a tub; a drum configured to be rotatable inside the tub; a weight balancer coupled to the tub; a vibration sensor provided in the tub; and a controller, wherein the controller is configured to compare an unbalance value of laundry in the drum with a reference value based on a driving current applied to a motor configured to rotate the drum, obtain an angular speed of at least one rotation axis of the tub based on an output value of the vibration sensor in response to the unbalance value of the laundry being less than the reference value, and determine whether the weight balancer is damaged based on the angular speed of the at least one rotation axis of the tub.

Abstract: A washing machine has a tub, a drum configured to be rotatable inside the tub, a weight balancer coupled to the tub, a vibration sensor configured to detect vibration of the tub while the drum is rotating, and at least one processor configured to determine whether a weight balancer is damaged based on a difference between a magnitude of the detected vibration of the tub at a fundamental frequency corresponding to a rotational speed of the drum and a magnitude of the detected vibration of the tub at a harmonic frequency of the fundamental frequency.
