A motor is a device that converts electrical energy into mechanical energy, allowing it to produce motion. Motors are commonly used in various applications, from household appliances like blenders and vacuum cleaners to industrial machines. They operate on the principle of electromagnetism, where electric current creates a magnetic field that drives the motor's components. There are different types of motors, including AC motors and DC motors, each suited for specific tasks. AC motors are typically used in applications requiring constant speed, while DC motors are preferred for variable speed control. Understanding how motors work is essential for many fields, including engineering and robotics.
