Abstract
The present disclosure relates to an apparatus and a method of reducing vibrations in a washing machine, and particularly, to an apparatus and a method of reducing vibrations in a washing machine that may predict a resonance frequency (or vibration generation region) before operating or driving a motor during a washing process to prevent a resonance phenomenon, thereby reducing noise and vibrations in the washing machine. To this end, the apparatus may include a motor configured to transmit rotational force; a motor driving unit configured to output a motor driving signal controlling an operation of the motor; and a filter configured to remove or reject a frequency or band causing a resonance phenomenon of the washing machine and allow another frequency or band to pass through in the motor driving signal output.
