the dc motor circuit


Posted on Feb 5, 2014

Choosing the right DC motor is critical when building mobile robots. Testing DC motors is an easy process and can be done by building a simple DC motor circuit. All that is required to build this circuit is a DC motor, a battery power source of at least 3 V, and red and black alligator leads. To build the circuit, the red alligator lead is connected to the positive terminal of the battery and motor, whereas the black alligator lead is connected to the negative terminal of the battery and motor. In order to control the functioning of a DC motor, a specialized DC motor circuit can be used, such as an H-bridge. The H-bridge circuit design is an array of transistors that work along with resistors and diodes to command a DC motor..
