When shopping around for a vacuum cleaner, its specifications are essential to know for its real world performance. The consumers of the vacuum cleaner want the type of vacuum cleaner that offers the best cleaning ability. Some consumers equate the cleaning ability of vacuum cleaner with ‘suction’ or another word ‘power’.
To understand the vacuum cleaner specifications must be a great challenge. Because ‘cleaning ability’ is not just about only suction or power. Although the cleaning ability is one of the main elements about vacuum cleaner specifications. There are some primary and some secondary specifications, which includes watts, amps, horse power, volts, air watts, air flow, water (lift or suction), capacity, filtration, cleaning tools, noise etc.
THE TYPE OF MOTOR USED IN VACUUM CLEANERS:
Vacuum cleaners motor is one of the main specifications to know about the cleaning ability of the vacuum. A universal motor is generally used in the vacuum cleaners as suction motors. The suction motor is one of the most important parts of a vacuum cleaner. It is this motor which takes the electrical power from the power source and converts it into mechanical power in the form of suction with airflow. Some technical terms associated with the suction motor include universal, series and brush type. All suction motors, except for the very small battery operated motors, are universal type motors since they can operate with either AC (alternating current) or DC (direct current) power sources. There is a motor rotating fan which creates the vacuum pressure and suction. At incredibly high speed of about 30,000 to 35,000 RPM, the impeller rotates. The power of the suction motor is usually calculated by multiplying the vacuum pressure and the rate of air flow which induces air flow from the brush and through the hose.

VACUUM CLEANER MOTOR SPECIFICATIONS:
A series DC motor is basically called a universal motor. The universal motor is specially designed to operate on AC current called alternating current as well as on DC which is called direct current. The universal motors are basically light in weight, these motors operate at high speed and the universal motors have high starting torque. The main quality about the universal motors that are used in the vacuum cleaners is that they are very easy to control. The universal motors for vacuum cleaners are generally noisy. The reason they become noisy are the commutator brushes attached in the vacuum cleaner. The wear in these commutator brushes makes the motor more noisier and that is why these type of motors are not preferred for continuous use.
The disadvantages that are applicable with DC motors are also associated with the universal motors because the concept of DC motors is much similar and closer to these types of universal motors as compared to the AC motors. That is why, most of the ‘original equipment manufacturers’ has started considering AC motors to overcome these disadvantages.
The universal motors in the vacuum cleaners contains stator windings with stator, rotar, an electric brush for providing 1000 to the rotar windings, a rotar winding that is inserted into the internal side of stator and a rectifier also. It features that the air slots with shield that is parallel to the motor shaft is arranged for brush and rectifier respectively. A few advantages of universal motors are high reliability and long service life.
The input power that goes into the motor of the vacuum cleaner is measured in watts. Although, this specification does not describe the efficiency of the motor that a vacuum cleaner contains. But a vacuum cleaners motor wattage is a valid way to evaluate and compare the power of the motor of a vacuum cleaner. The ideal comparison of motor is input power of product A in watts is compared to the input power of product B in watts. The ideal comparison of one vacuum cleaner brand is harder to another brand of vacuum cleaner. It is because the manufacturer of vacuum cleaners sometimes does not provide motor input specifications in watts but they rate the entire vacuum cleaner in amperes. very common vacuum cleaner specification is amps. The amperage rating designates the maximum amount of electrical current used by all of the vacuum cleaner’s electrical components when operating. The biggest consumer of electrical current will be the vacuum motor, but the amperage rating includes all of the electrical components, including the vacuum motor, the power nozzle motor, the light bulb, etc.
There is a specification in the vacuum cleaner which is known as ‘water lift’ or ‘sealed suction’. The rating for this sealed suction is taken when the motor gets totally sealed. This term refers about how many inches the motor of the vacuum cleaner vertically lifts a 1 inch column of water. The air flow system in the vacuum cleaner takes account to the power of vacuum motor that creates suction and also creates resistance of the bag and filter system that the air must pass through.

Frequently Asked Questions:
Is vacuum cleaner motor powerful?
The vacuum cleaner motors, also called suction motor usually draws 7 to 12 amperes of the current from the electrical power source in which maximum of current is about 12 amperes is permitted to any house hold appliance that plugs into a standard house hold electrical outlet.
Which vacuum cleaner contains the most powerful motor?
The vacuum cleaner ‘The Purvac Killer Whale’ is known to have the biggest and powerful central vacuum with 1,347 air watts. This is a dual motor with 240 volts system. It becomes more powerful when it comes to suction. This motor type and vacuum cleaners are designed for larger sized areas and homes.
Are vacuum cleaner motors universal?
Yes, the motors of vacuum cleaners are universal. The main quality about the universal motors that are used in the vacuum cleaners is that they are very easy to control. The universal motors are basically light in weight, these motors operate at high speed and the universal motors have high starting torque.
