    Abstract: Provided are a phase current estimating apparatus, and a motor controlling apparatus and a motor system comprising the same. The phase current estimating apparatus according to an embodiment of the present invention receives a DC voltage from a power supply unit and operates the motor system for driving a motor by generating a multi-phase AC signal in response to a drive signal. The phase current estimating apparatus can detect a DC link current from a link to which direct voltage is supplied, output an input signal by filtering with a first time constant in a section where the DC link current is detected, and output the input signal by filtering with a second time constant in a section where the DC link current is not detected.
