You may have noticed that new vacuum cleaner motors are much smaller and more compact than old ones.
Universal motor used in vacuum cleaner.

The universal motor is a type of electric motor that can operate on either ac or dc power and uses an electromagnet as its stator to create its magnetic field.
In this case the shaft is coupled to one or more fans or blower wheels.
Universal motors have high starting torque operate at high speed and are lightweight.
Bidirectional motors using two coils on the stator can be driven by applying a voltage to only one of them for the respective direction.
The universal motor is a series dc motor that is specially designed to operate on alternating current ac as well as on direct current dc.
Recall a little motor theory.
This is a trend in the vacuum motor industry.
A universal motor is typically used as suction motor across vacuum cleaners.
The universal motor is a series dc motor that is specially designed to operate on alternating current ac as well as on direct current dc.
Universal motors have high starting torque operate at high speed and are lightweight.
Most universal motors are unidirectional.
As mentioned above one of the most popular uses for universal motors is in vacuum motors and blowers.
The universal motor is very similar to a dc series motor in construction but is modified slightly to allow the motor to operate properly on ac power.
It is often referred to as an ac series motor.
Typically a universal motor has been used as suction motor across vacuum cleaners.
