I'm a physics teacher and I've found it hard to explain motor's working to a couple of students.
The key components of a motor are the stator (stationary part), rotor (rotating part), and the power source (such as electricity or fuel). The stator contains the windings, which are coils of wire that produce a magnetic field. The rotor contains the armature, which is a set of electromagnets that interact with the stator's magnetic field to generate motion.
A motor converts electrical energy into mechanical energy through the interaction between the stator and rotor. When an electric current is passed through the windings in the stator, it creates a magnetic field. This magnetic field interacts with the magnetic field of the armature in the rotor, causing the rotor to rotate.
Brushes and commutators are used to transfer the electric current from the power source to the rotating part of the motor. The brushes are carbon blocks that make contact with the commutator, which is a segmented metal ring attached to the rotor. As the rotor rotates, the brushes and commutator work together to switch the direction of the electric current, allowing the motor to continue spinning.
Torque is the force that causes an object to rotate around an axis. In a motor, torque is produced by the interaction between the magnetic fields of the stator and rotor. The more powerful the magnetic field, the greater the torque and the stronger the motor's ability to rotate.
Motors have a wide range of applications in our everyday lives. Some common examples include electric fans, washing machines, elevators, and cars. Motors are also used in industrial settings for machinery and in robotics for precise movements and control.
