You are connected as. Connect with: Use your name: Inside the stator, there's the coil, mounted on an axle that spins around at high speed—and this is called the rotor.

The rotor also includes the commutator. Universal motors DC motors like this are great for battery-powered toys things like model trains, radio-controlled cars, or electric shavers , but you don't find them in many household appliances. Small appliances things like coffee grinders or electric food blenders tend to use what are called universal motors, which can be powered by either AC or DC.

Unlike a simple DC motor, a universal motor has an electromagnet, instead of a permanent magnet, and it takes its power from the DC or AC power you feed in: When you feed in DC, the electromagnet works like a conventional permanent magnet and produces a magnetic field that's always pointing in the same direction. The commutator reverses the coil current every time the coil flips over, just like in a simple DC motor, so the coil always spins in the same direction.

When you feed in AC, however, the current flowing through the electromagnet and the current flowing through the coil both reverse, exactly in step, so the force on the coil is always in the same direction and the motor always spins either clockwise or counter-clockwise.

What about the commutator? The frequency of the current changes much faster than the motor rotates and, because the field and the current are always in step, it doesn't actually matter what position the commutator is in at any given moment.

Animation: How a universal motor works: The electricity supply powers both the magnetic field and the rotating coil. With a DC supply, a universal motor works just like a conventional DC one, as above.

With an AC supply, both the magnetic field and coil current change direction every time the supply current reverses. That means the force on the coil is always pointing the same way. Photo: Inside a typical universal motor: The main parts inside a medium-sized motor from a coffee grinder, which can run on either DC or AC. The gray electromagnet round the edge is the stator static part and its powered by the orange-colored coils. Note also the slits in the commutator and the carbon brushes pushing against it, which provide power to the rotor rotating part.

Induction motors in such things as electric railroad trains are many times bigger and more powerful than this, and always work using high-voltage alternating current AC , instead of low-voltage direct current DC , or the moderately low voltage household AC that powers universal motors. Other kinds of electric motors In simple DC and universal motors, the rotor spins inside the stator. The rotor is a coil connected to the electric power supply and the stator is a permanent magnet or electromagnet.

Large AC motors used in things like factory machines work in a slightly different way: they pass alternating current through opposing pairs of magnets to create a rotating magnetic field, which "induces" creates a magnetic field in the motor's rotor, causing it to spin around. You can read more about this in our article on AC induction motors.
