Who invented generator?
How can you tell if a motor is universal?
Look for the stator core construction and rotor. If there is no commutator, then it is a AC motor. If there is a commutator and brushes, it may be either a DC motor or an AC commutator motor (Universal motor).
Which motor is known as universal?
This is a type of AC commutator motor. Although mainly used on single-phase AC, it rotates on both AC and DC power. It is also called a “universal motor” or “commutator motor”. Its major applications are electric vacuum cleaners, power tools, and juicers.
