Although it is called a vacuum cleaner, it does not actually create a vacuum. Inside the cleaner there is an electric motor which drives a fan blade. This fan blows air out of the vacuum cleaner and this causes air to be drawn in to the cleaner at the other end. Thus the cleaner works by creating an air flow, not a vacuum.
The motor in a vacuum cleaner is an electromagnetic device.
universal motor
It is NOT the electric motor creating that sound, it is the suction pump that is driven by the motor that is creating that sound while creating the partial vacuum that sucks in the dirt. If you have an upright vacuum cleaner, the beater brushes also make quite a bit of noise when you have them turned on when doing carpets.
If the vacuum cleaner is powered by electricity this is used to turn the electric motor which is needed to create the suction or vacuum. That motor either has permanent magnets inside it, or the current passes through many "turns" of wire to create magnets when you switch the cleaner on. Early experiment in electricity showed that if a wire is moved in a magnetic field some current is created. Similarly, if a magnet is moved near to a wire the same result occurs. So, yes the cleaner does need a magnet.
Vacuum Cleaner and Floor Polisher are both built with motor or machine that needs the power of electricity to work and function.
A 12-amp motor is fairly standard and will be about as loud as a typical vacuum cleaner, that is to say loud enough to scare gunshy dogs and babies but not loud enough to be overbearing.
what do you get when you cross a motor bike driver with a vacuum cleaner? A 'DIRT BAG''.
it is so important because with out a motor driven vacuum it would be harder to vacuum clean also how would you clean without a vacuum cuz using a broom is hard
The motor has to be replaced the most. Make sure you buy a high end vacuum that will last a long time. If you get a cheap vacuum the motor will burn out often and it is expensive to fix them.
Some of the air handling dampener motors are vacuum controlled and some have a small electric motor. If it's a vacuum controlled dampener, you probably have a vacuum leak, faulty vacuum diaphragm or disconnected vacuum line. If it's an electric dampener motor you have a bad connection, faulty feedback switch or faulty motor assembly.
The vacuum cleaner is going to need a new motor soon.
