A DC motor is an electrical device 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 widely used in various applications, from small toys to industrial machinery, due to their simplicity and efficiency. DC motors come in different types, including brushed and brushless designs. Brushed DC motors use carbon brushes to transfer electricity to the motor windings, while brushless motors use electronic controllers for operation. Both types are valued for their speed control and torque characteristics, making them suitable for diverse tasks.
