More Information
Summary:Handy electrical equipment, the manufacturing cost of which is low, is provided in which an electric motor is controlled so that a higher harmonic current can be in a range of a predetermined standard value and simultaneously vibration generated from the electric motor is suppressed. A plurality of taps (1c) to (1h) are drawn out from stators (1a), (1b) of electric motor (1). When the taps are switched, an input to electric motor (1) is switched. When common phase control is conducted in it, vibration generated from electric motor (1) is suppressed. When the tap is switched in a region in which a higher harmonic current is low, a level of the higher harmonic current is reduced in all regions.
