A control method for a home appliance including a motor that is driven by a driving current. The control method includes (a) receiving a stop signal to stop the motor, (b) based on receiving the stop signal, performing open brake control that stops supply of the driving current to the motor, (c) based on a motor phase current of the motor at a start of the open brake control, estimating an initial motor speed of the motor at the start of the open brake control, (d) based on the estimated initial motor speed, determining a start time point of short brake control that applies a torque in a reverse direction to a rotation direction of the motor, and (e) performing the short brake control at the determined start time point of the short brake control.
