Portable fan based on high-speed three-phase motor and control method thereof

Abstract

The invention discloses a portable fan based on a high-speed three-phase motor and a control method thereof.The portable fan comprises a control module, a driving module and the high-speed three-phase motor, the working voltage of the high-speed three-phase motor ranges from 2 volts to 18 volts, the working current of the high-speed three-phase motor ranges from 0.1 amperes to 10 amperes, and / or the limit working power of the high-speed three-phase motor ranges from 0.5 watt to 100 watts; and the control module controls the rated working rotating speed of the high-speed three-phase motor through the driving module according to the working voltage, the working current and / or the rated working power, so that the high rotating speed noise of the high-speed three-phase motor is reduced, and the wind speed is controlled to be within a preset wind speed interval. According to the technical scheme, the control module, the driving module and the high-speed three-phase motor are combined, the portable fan solution which is efficient, low in noise and capable of adjusting the wind speed is provided, the portability and use comfort of the fan are improved through the low-voltage driving technology and the control strategy, and the user experience is improved.
