Problems solved by technology

Therefore, under the limitation of the structure of the single-phase AC motor itself, the conversion rate of useful work under the same conditions is low.
[0004] In addition, ordinary floor fans generally use single-phase AC motors. Therefore, after the mains power failure, if AC220V power cannot be provided, the fan cannot be used, that is, a 220V power socket must be provided for power supply, thus limiting its flexibility and convenience. , so that it cannot be moved to a place far away from the socket at will, or provide a more suitable placement

Abstract

The invention provides a three-phase brushless direct-current fan motor. The motor is a three-phase brushless direct-current motor and comprises a motor main body and a driver, the driver is electrically connected with a 24V power adapter, stator windings in the motor main body are connected in a three-phase symmetrical star manner. The three-phase brushless direct-current fan motor provided by the invention has the advantages of simplicity in commutation, a long service life and low noise, and is convenient to use.

Description

technical field [0001] The invention relates to the electromechanical field, in particular to a three-phase brushless DC fan motor. Background technique [0002] At present, the floor fan adopts AC220V AC motor. This AC motor adopts a capacitor phase-separated single-phase motor, so it is generally called a single-phase AC fan motor. It includes two windings, the main winding is the running winding, and the secondary winding is the starting winding; The winding is directly connected to the AC220V power supply, and the secondary winding is connected to the AC220V power supply after the capacitor is connected in series. By starting the phase-shifting effect of the capacitor, the single-phase alternating current is separated into another alternating current with a phase difference of 90 degrees. Send these two phases of alternating current into two or four sets of motor coil windings respectively, so that a rotating magnetic field is formed in the motor, and the rotating magne...
