A DC 모터 (Direct Current Motor) is an electric motor that runs on direct current electricity. It converts electrical energy into mechanical energy, allowing it to drive various devices and machines. These motors are commonly used in applications like toys, fans, and electric vehicles due to their simplicity and efficiency. The operation of a DC 모터 relies on the interaction between magnetic fields and electric currents. When electricity flows through the motor's coils, it creates a magnetic field that interacts with permanent magnets or other coils, causing the rotor to spin. This spinning motion can then be harnessed to perform work.
