A motor driving unit (1) includes a controller (15) that performs driving control of a motor (3) by controlling an inverter (11). During regeneration of the motor (3), the controller (15) performs output stopping control for causing the inverter (11) to stop an output, when an inter-terminal voltage of a capacitor (12) is equal to or greater than a first threshold value. The controller (15) performs output restarting control for causing the inverter (11) to restart the output, when the inter-terminal voltage of the capacitor (12) is equal to or smaller than a second threshold value which is smaller than the first threshold value. The controller (15) performs regenerative braking by allowing the output stopping control and the output restarting control to be repeatedly performed.
