How does an electric motor work?
Quick answer
An electric motor works by using electricity to create magnetism, which pushes and pulls to spin a shaft. A current flows through coils inside a magnetic field, and the resulting force turns the motor — converting electrical energy into motion.
Step by step
- Current flowing through a coil turns it into an electromagnet.
- That coil sits between fixed magnets, so it's pushed and pulled.
- Clever switching keeps the force turning the shaft in one direction.
- It converts electrical energy into rotational motion.
- Motors run everything from fans and drills to electric cars.
People also ask
How does an electric motor spin?
Current makes a coil magnetic; attraction and repulsion with surrounding magnets push it around, and switching the current keeps it rotating.
What keeps a motor turning the same way?
A commutator or electronic controller flips the current at the right moments so the magnetic push always continues the spin.
Is an electric motor efficient?
Very — good motors turn well over 85% of electrical energy into motion, far more efficient than burning fuel.
How does an electric motor work?
Current through a coil in a magnetic field creates a force that spins the coil, turning electricity into motion.
What's the difference between a motor and a generator?
A motor turns electricity into motion; a generator does the reverse, turning motion into electricity.
Why are electric motors used in EVs?
They're efficient, quiet, low-maintenance, and deliver instant torque from a standstill.
