Abstract: A washer includes a drum, a motor connected to the drum, a motor drive connected to the motor and configured to supply a driving current to the motor to rotate the drum, and a processor connected to the motor drive. The processor is configured to control the motor drive to supply the driving current to the motor to rotate the motor at a target speed and to determine a magnitude of a load accommodated in the drum while controlling a rotational speed of the motor within a predetermined range.
