What are the applications of micro DC motors in vacuum cleaners?
Leave a message
The working principle of the vacuum cleaner is to use a micro motor to drive the fan blades to rotate at a high speed, so that a certain air negative pressure suction is generated in the sealed shell to achieve the function of vacuuming. Vacuum cleaners are relatively common household appliances, which can be divided into vertical, horizontal and portable. , The working principle of the vacuum cleaner is to use a micro motor to drive the fan blades to rotate at a high speed, so that a certain air negative pressure suction is generated in the sealed shell to achieve the function of vacuuming. Today, I will introduce the application of micro DC motor in vacuum cleaner.
The performance requirements of vacuum cleaners for micro DC motors are high speed, large torque and small volume, while for household vacuum cleaners, single-phase series motors are often used, but the mechanical characteristics of series motors are relatively hard, and when the load changes in a large range, the motor The speed changes little.
The small portable car vacuum cleaner adopts a permanent magnet micro DC motor and is powered by a battery. Generally, the rated voltage is about 12V~24V. Depending on the type of car vacuum cleaner, the speed is generally 16000rpm~36000rpm. The higher the speed, the greater the suction. In addition to being driven by DC, the portable car vacuum cleaner has the advantage of large starting torque. When the DC motor is customized with a control voltage, the rotor will rotate immediately, so the starting is very fast and the sensitivity is high.
Generally, the service life of the carbon brush motor is about 500~1200 hours, which is determined by the quality of the carbon brush and the speed of the motor. For example, if a household vacuum cleaner chooses a DC motor, a brushless DC motor is generally selected.
