What is the moter and working principle

Question

Accepted Answer

A motor is a device that converts electrical energy into mechanical energy through electromagnetic principles.

Motors are used in various applications such as electric vehicles, industrial machinery, and household appliances.
The working principle of a motor involves the interaction between magnetic fields and electric currents.
Electric current flowing through a coil in the motor creates a magnetic field, which interacts with the magnetic field of a permanent magnet or electromagnet.
This interaction generates a force that causes the coil to rotate, resulting in mechanical motion.
Different types of motors include DC motors, AC motors, stepper motors, and servo motors.
For example, a DC motor uses a split-ring commutator to reverse the direction of current flow in the coil, allowing continuous rotation.
AC motors rely on the changing direction of alternating current to produce a rotating magnetic field.
Stepper motors move in discrete steps and are commonly used in robotics and precision control systems.
Servo motors use feedback control to achieve precise positioning and are often found in robotics and automation.
