    • A phase current estimation apparatus for a motor capable of suitably improving estimation accuracy of phase currents is provided. The phase current estimation apparatus 10 of the motor includes a control unit 24 that decomposes a command voltage vector Vdq into two vector components V′dq in the case where a magnitude of the command voltage vector Vdq is less than a predetermined lower limit voltage Vlow, so that the command voltage vector Vdq is allowed to have the magnitude equal to or more than the predetermined lower limit voltage Vlow for every two adjacent periods in units of a period of a carrier signal and to have the phase outside a predetermined phase range including phases of reference voltage vectors. Accordingly, the control unit 24 can quantitatively analyze harmonic components, which are generated by decomposing the command voltage vector Vdq into the two vector components V′dq, by using mathematical equations.
