Leave your queries and feedback about this circuit in the below comments section.The BLDC motor is rapidly gaining popularity by its utilization in various industries, such as Appliances, Automotive, Aerospace, Consumer, Medical, Industrial Automation Equipment and Instrumentation. Also in case if you are powering the circuit using a battery you should have in mind that the current intake of motor should be less than current draw capacity of the battery. To do this you should make sure your MOSFET is capable of handling the current intake of motors used here. You can add motors in similar manner to control it altogether. So the motor now receive 0V from Q1 and 12V from Q2, therefore changing the direction of motor’s rotation. But when we press the button we put the transistors in saturation state. When the button is not pressed the transistor will be in open state and the Motor receives 12V from the drain of the FET Q1 on its positive pin. When both source are connected to ground or negative terminal of the battery we will have the output for our DC motor in Q1’s drain pin and Q2’s source.Ĭonnecting a button between the battery and each of the gates of FET can be used to control the ON/OFF state of transistor. Source pin of both the MOSFET’s are connected to ground or negative terminal of the battery. A Switch Sw1 connects it directly to the Gate of both the MOSFET. If you are looking for motor driver circuit to be used with Microcontroller or Development boards consider this Bidirectional motor control circuit for ease of use and have more control over the motor movements.įirst we have our source of energy a 12VDC Battery. In fact it takes only very few components and can be built pretty easily. This circuit can be used as a Motor driver in different projects. In this circuit the DC motor keep on running in one direction until when the switch is pressed it reverses its direction. This is a DC motor driver circuit using a single N channel MOSFET.
