Vacuum Cleaner Motor Suction

　　In modern home life, vacuum cleaners have become a necessity for every household. The working principle of the vacuum cleaner is that the internal motor rotates at high speed, sucks air from the inlet, and the vacuum pressure difference is generated inside, the dust enters the dust cup or dust bag through the suction port, the dust is left in the dust bag, the filtered air is discharged, the finer the filter material, the cleaner the filtered air, but it will affect the rate of vacuuming, depending on the user's choice. Now vacuum cleaner in addition to the role of vacuuming, but also mopping, dry cleaning carpet, mite removal and other functions, like finger butler vacuum cleaner also has anti-virus function, a wide variety, it can be said that every family can find a vacuum cleaner that is suitable relative to itself.

　　The suction power of the motor is affected by the motor type, speed and vacuum

　　At present, there are two main types of vacuum cleaner motors,

　　Brushed motor is the use of magnetic field opposite-sex attraction, same-sex repulsion principle to promote the motor rotation, it was developed very early, the technology is relatively mature, brushed motor has no obvious shortcomings, that is, life, speed, energy saving, maintenance are weaker than brushless motor.

　　Brushless motor, fast speed, low volume, long life.

　　Speed is one of the core factors that determine the vacuum cleaner suction efficiency, and generally more than 1,000 yuan vacuum cleaners can generally reach 100,000 rpm.

　　After the motor of the vacuum cleaner discharges the air in the inner cavity of the machine, it forms a state similar to vacuum, and the air inside is less, and naturally forms a negative pressure with the outside world, that is, the vacuum degree, the parameters are expressed in kpa, representing the vacuum negative pressure of the vacuum cleaner, and some places are called "static pressure". It represents the static pressure of the machine, which is equivalent to the theoretical suction power when blocking the suction port, but under normal circumstances, the suction power is lost, so KPa cannot absolutely represent the size of the suction power.

　　Application environments of different KPAs,

　　The suction power of 1000pa~8500pa can inhale dust, mites and hair, which are relatively light and small, and this suction power will be used on the electric mattress suction head.

　　12500pa ~ 20000pa suction can suck in paper towels, grains and other heavier things, usually also suck farther, because the gap may roll into the grain, so this suction will be used in the gap suction tip.

　　The suction power of 28000pa can suck in things that are similar to the weight of ceramic fragments, so the main suction head of the general household vacuum cleaner motor will use more than 28000pa of suction power, which can achieve thorough cleaning of the ground.
