How electric motors work

The rotation principle of the motor is based on the Fleming left hand rule. When a wire is placed in a magnetic field, if a current is applied to the wire, the wire will cut the magnetic field line to make the wire move. The electric current enters the coil to generate a magnetic field, and the magnetic effect of the current is used to make the electromagnet rotate continuously in a fixed magnet, which can convert electrical energy into mechanical energy. The principle of a DC motor is that the stator does not move and the rotor moves in the direction of the force generated by the interaction. Ac motor is the stator winding coil through alternating current, generating rotating magnetic field, rotating magnetic field attracts the rotor together for rotating motion DC motor basic structure includes "armature", "field magnet", "collector ring", "brush".

Armature: A soft iron core that can be rotated around an axis to wind a multi-coil. Field magnet: A powerful permanent magnet or electromagnet that generates a magnetic field. Collector ring: two semicircular collector rings connected to the two ends of the coil, which rotate with the coil to change the direction of the current. The current in the coil changes direction every half turn. Brush: Usually made of carbon, the collector ring contacts a fixed position of the brush, used to connect to the power supply.

There are many kinds of motor, in terms of its basic structure, its composition is mainly composed of stator and rotor. While the stator is stationary in space, the rotor rotates around the shaft and is supported by bearings. There is an air gap between the stator and the rotor to ensure that the rotor can rotate freely. The stator and rotor are wound with a coil, and a magnetic field is generated by the current, which becomes an electromagnet. One of the stator and rotor can also be a permanent magnet.
