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.

An interior permanent magnet motor includes a stator provided with a plurality of slots and a rotor rotatably disposed inside the stator. A plurality of permanent magnets of the same polarity are disposed at equal intervals in a circumferential direction inside the rotor. A plurality of flux bathers are provided on left and right sides of one end of each of the plurality of permanent magnets adjacent to an outer circumferential surface of the rotor. A ratio of a number of slots of the stator to a number of magnetic poles of the rotor is 3:2 or 3:4. The number of permanent magnets provided in the rotor is &#xbd; of the number of magnetic poles of the rotor.
