The invention provides a motor driving apparatus, a home appliance including the same and a mobile terminal. A motor driving apparatus provided by the embodiment of the invention includes an inverter having a plurality of switching devices, wherein the inverter converts a direct current (DC) power into an alternating current (AC) power according to switching of the switching devices and supplies the AC power to a motor, and a controller to control the inverter, wherein the controller performs a control operation such that a switching frequency of the respective switching devices of the inverter remains constant in a first mode corresponding to a motor operation mode and performs a control operation to change the switching frequency of the respective switching devices of the inverter in a second mode corresponding to a sound output mode for fault diagnosis to output sound corresponding to the changed switching frequency. Thus, sound related with fault diagnosis can be output easily and conveniently by use of the motor.
