Abstract

A harmonic current attenuating apparatus of a motor 30 which controls a rotation speed of the motor 30 by phase-controlling a sine wave AC power supplied from a power supply unit 10 and attenuates the harmonic current generated at a phase-controlling mode of the AC power by way of an harmonic current attenuating unit wherein the apparatus comprises: a manipulating unit 34 for selecting a phase-controlling mode or a full power operation mode according to manipulation of a user; and a switching unit 21 for supplying the AC power supplied from the power supply unit 10 through the harmonic current attenuating unit 20 to the motor 30 when the phase-controlling mode is selected by the manipulating mode, and for supplying the AC power from the power supply unit 10 directly to the motor 30 when the full power operation mode is selected, such that there is an advantage in the harmonic current attenuating apparatus of a motor in that it effectively attenuates the harmonic current through a harmonic transformer 20 at the phase-controlling mode and substantially improves an output of the motor 30 by directly supplying the AC power from the power supply unit 10 to the motor 30 without phase-controlling at a full power operation mode. The unit 21 may be a triac (Figs 6 and 7). The motor may be used to drive a cleaner.
