Vacuum Cleaner Motors
Vacuum cleaners use a pump to absorb the dust and dirt from tiled and
carpeted floors. The pump creates a partial vacuum, which gives vacuums
the ability to pull in external air and save it in a filtering bag for
later disposal.
The vacuum cleaners suction motor is a fundamental part of its system.
Suction motor in vacuum cleaners takes the electrical power from the
power source and converts it into mechanical power in the form of
suction with air flow. The motor is designed in such a way that it
produces a partial vacuum inside the vacuum cleaner body.
This causes a drop in the pressure between the two ends of the suction
pipe - one of which attaches the vacuum cleaner body to the filter bag.
However, the other one has an open end, which actually takes in the
dust.
The suction is the maximum pressure difference that the pump can create.
The higher the suction power, the more powerful the cleaner.
Power of the Vacuum Cleaner Suction Motor
The power of the vacuum cleaner suction motor is suggestive of its
performance.
To generate strong suction, the motor has to turn at a fast speed and
hence requires more input source power. Thus, it is essential to
understand the relationship between suction and speed to understand the
term power in lieu of a vacuum cleaner.
There are many ways in which the power of the vacuum cleaner can be
defined including Peak Horse Power (PHP), Amperage (amps), Air Watts and
Air Flow.
Power is usually mentioned in Watts, which is a multiple of
amperes and voltage. This is a measure of the input power of the motor
or in simple terms the electricity consumption by any vacuum cleaner
motor. The calculation is: Domestic vacuum cleaner of 12 Amps and 120
volts makes ~1400 watts.
Peak Horse Power is usually measured by counting rotations per
second of the suction motor without its fans and adding as much load as
possible without burning it out. It is usually an exaggerated output of
a vacuum cleaner suction motor rating. Peak Horse Power rating isn’t
used anymore.
Air Watts is the outer power of the vacuum cleaner. It is the
combined effect of suction produced by the suction motor as well as the
internal resistance to air flow like air turbulence in hosepipe,
congestion in cleaning nozzle contacts and resistance in filtering
system. Air Watts is measured as follows:
Air Watts = (Air Flow * Vacuum)/8.5
The Air flow is in Cubic Feet per Minute (CFM) and the Vacuum is in
Inches of Water Lift.
While the power generated by the suction motor is not the most essential
feature of the vacuum cleaner it is an aspect to consider when comparing
various vacuum cleaners.
There are a couple of other important vacuum cleaner performance
features like the brushing action, air flow, filtration efficiency and
dust bag which all combine to create an efficient vacuum cleaner.
Which vacuum cleaner suction motor should you choose?
The first step in choosing the suction motor is to analyze your cleaning
requirements.
- Residential vacuums are usually
inexpensive and light-weight.
- Commercial vacuum cleaners are
usually available in two types. Upright vacuum cleaner and the back
pack vacuum cleaner.
Floor maintenance personnel usually
utilize a wet dry vacuum cleaner for removing old stripper and water
from newly refinished floors. Contactors and construction crews usually
use a commercial heavy duty vacuum for construction cleanup and
renovations. There is a separate suction motor designed for each type.
