Here we will explain the operating principle of motors. -
Magnetic Force <How Does a Motor Work? (1)>
Around a permanent magnet having a rotational axis when the outer magnets rotate (referred to as a rotating magnetic field), the N and S poles attract and repel each other, causing the magnet with the rotational axis (center) to turn. This is the basic operating principle of a motor. -
3-phase AC <How Does a Motor Work? (2)>
Here we see an actual method used for rotating a motor by generating a rotational magnetic field from a 3-phase AC source and conductive coils (3-phase AC is an AC signal with phases shifted 120°).
