Abstract
A method of braking a washing machine from an operational speed to a zero speed is provided (as well as a washing machine incorporating the method) for a washing machine driven by one of a synchronous or asynchronous motor. Upon receipt of a stop signal, collapsing the motor rotating magnetic fields are collapsed for a predefined time period. After the predefined time period, DC braking voltage is applied to the motor stator windings at a controlled ramp-up rate to a fixed amplitude to generate a controlled ramped braking torque on the motor. The braking torque is applied until the motor is stopped.
