Abstract: Disclosed herein are a motor driving apparatus and a home appliance including the same. The motor driving apparatus includes a direct current (DC) link capacitor, an inverter, a DC link voltage detector, and a controller. The controller controls rheostatic braking to be performed in order to stop the motor, performs bootstrap operation of gate terminals of the upper arm switching elements of the inverter during a first period for starting the motor, and determines whether the motor stops during the first period based on the DC voltage detected by the DC link voltage detector or the output current detected by the output current detector. Accordingly, it is possible to conveniently determine whether the motor stops in the sensorless type motor driving apparatus.
