1) The motor rotates with the help of magnets and magnetic forces
Around a permanent magnet with a rotating axis, ① the rotating magnet (generates a rotating magnetic field), ② according to the principle of
opposite polarity attraction and same level repulsion between the N and S poles, ③ the magnet with a rotating axis will rotate.
This is the basic principle of motor rotation.
The current flowing through the wire generates a rotating magnetic field (magnetic force) around it, causing the magnet to rotate, which is actually the same action state.
In addition, by winding the wire into a coil shape, the magnetic force is synthesized to form a large magnetic flux (magnetic flux), producing N and S poles.
Inserting an iron core into a coil shaped wire makes it easier for magnetic lines to pass through, generating stronger magnetic force.
2) Actual rotating motor
Here, as a practical method for rotating motors, we introduce the method of using three-phase AC and coils to manufacture a rotating magnetic field.
(Three phase AC is an AC signal with a phase interval of 120 °)
The synthesized magnetic field in state ① above corresponds to Figure ①.
The synthesized magnetic field in state ② above corresponds to Figure ②.
The synthesized magnetic field in state ③ above corresponds to Figure ③.
As mentioned above, the coils wound around the iron core are divided into three phases, with U-phase coils, V-phase coils,
and W-phase coils arranged at 120 ° intervals. The coils with high voltage produce N poles, while the coils with low voltage produce S poles.
Each phase changes according to a sine wave, so the polarity (N pole, S pole) and magnetic field (magnetic force) generated by each coil will change.
At this point, looking at the coil that produces N poles, it rotates in the order of U phase coil → V phase coil → W phase coil → U phase coil.
