Abstract
In this study, first, an equivalent circuit of a permanent-magnet synchronous motor (PMSM) and a dynamic model of a washing machine are derived; second, a method for deriving the unbalance mass from the ripple of the current flowing through the electric motor is suggested; and finally experimental verification of the results are conducted.
