The present invention relates to a motor driving apparatus and a home appliance comprising the same. The motor driving apparatus according to an embodiment of the present invention comprises: an inverter which converts a direct current power source of a DC stage capacitor to an alternating current power source and outputs the converted alternating power source to a motor by a switching operation; a DC stage resistance device arranged between the DC stage capacitor and the inverter; and a control unit which controls the inverter on the basis of phase current sampled by means of the DC stage resistance device, wherein the control unit controls the frequency of voltage applied to the motor or the rotation frequency of the motor to be synchronized with the sampling frequency of the phase current sampled via the DC stage resistance device. Accordingly, it is possible to accurately calculate the phase current flowing through the motor by means of the DC stage resistance device.

Motor driving apparatus and home appliance comprising same

The mobile terminal includes a wireless communication unit configured to receive terminal position information and object related information of at least one object corresponding to the terminal position information; a display module configured to display at least one object indicator indicating the at least one object and display a storage target object indicator region on a background image corresponding to the terminal position information; a user input unit configured to receive a selection of an object indicator; a memory configured to store object related information; and a controller configured to control the components of the mobile terminal. The display module is further configured to display an identifier corresponding to the selected object indicator within the storage target object indicator region, and display an object item list including an object item corresponding to the stored object related information.
