DC motor

Conventional DC motors have two wires and run when a current is passed through them. They are the most common kind of electrical motor. They come in many different shapes and sizes.



Most electric motors run at many thousands of revolutions per minute (RPM). In addition, the actual output is frequently not very powerful. To be useful for most applications, this raw output of the motor needs to be geared down. This provides a slower turning shaft with much greater torque.
