A DC brush motor and a DC brushless motor are two types of DC motors that differ in their structure and characteristics. A DC brush motor uses brushes and commutators to switch the current to the coils, while a DC brushless motor uses an electronic controller to switch the current to the coils. A DC brush motor has advantages over a DC brushless motor, such as lower cost, simpler design and easier speed control. However, a DC brushless motor has advantages over a DC brush motor, such as higher speed, longer lifespan, lower noise and less heat generation.
