A DC motor is an electric motor that converts direct current (DC) electrical energy into mechanical energy. It operates on the principle of electromagnetism, where a magnetic field interacts with a current-carrying conductor to produce motion. These motors are commonly used in various applications, including toys, appliances, and electric vehicles. DC motors come in different types, such as brushed and brushless. Brushed DC motors use brushes to transfer current to the motor windings, while brushless DC motors use electronic controllers for operation. Both types are valued for their simplicity, efficiency, and ease of control, making them popular in many industries.
