What is a Motor?
How does a motor work? (1)
1) Motor rotation using a magnet/magnetic force
The basic operating principle of a motor is as follows.
Around a permanent magnet having a rotational axis,① When the outer magnets rotate (referred to as a rotating magnetic field),② The N and S poles attract and repel each other, ③ Causing the magnet with the rotational axis (center) to turn.
Alternatively, supplying current to a conductor generates a magnetic field around, creating a rotational magnetic field (magnetic force). This results in the same effect as rotating a magnet.
However, if we wind a conductive wire into a coil the magnetic force is combined, generating a large magnetic flux along with N and S poles.
