This application relates to a brushless DC motor for a booster pump and a booster pump. The rotor assembly is sleeved outside the rotating shaft, and the rotor assembly is used to drive the rotating shaft to rotate together; the stator assembly is used to be fixed on the outside, and the drive plate is fixed on the stator assembly to drive The plate is used to control the change of the magnetic field of the stator assembly through the control circuit, so as to drive the rotor assembly to rotate. The above-mentioned brushless DC motor for the booster pump uses a drive board to replace the commutator and carbon brush commutation structure of the traditional brushed motor, and cooperates with the structural design of the rotor assembly and stator assembly. On the one hand, it has simple structure, long life, and low noise. and high efficiency; on the other hand, it is beneficial to achieve accurate control of current and voltage through the drive board, thereby accurately controlling the speed of the rotating shaft and preventing rotor demagnetization, thereby improving the control of boost output; on the other hand, it is conducive to simplifying the rotor assembly and The structure of the stator assembly and the processing technology of the rotor are relatively simplified, which reduces the product cost and is convenient for installation and use.
Description
