In this method, the field winding is excited by a constant voltage but the armature winding is supplied with different voltages through switching devices. The speed of the motor will be proportional to the armature voltage.
The two machines are connected in series with each other and a starting resistance as shown below in figure(a). The starting resistance is gradually cut out as the motor attains the speed.
Hey I'm Dejan, a maker, a techie and a mechatronics engineer. I love making electronics and robotics projects for you to learn and make something cool on your own.
Connect the potentiometer to one terminal of the DC motor. Attach the wire to the unused middle pin on the potentiometer. This is best done using a wire instead of directly so that the potentiometer can be easily controlled without the motor application interfering.
Suppose the slider of the potentiometer is adjusted so that the voltage at its slider is 3V. Since the slider terminal is connected to A0 pin, the voltage at A0 pin will be also 3V.

But here we look at just three coils, spaced at 120º. A motor, as we noted in our last session, performs the task of converting electrical energy into mechanical energy. So how does the motor in our illustration do this? Let’s look at what goes on inside.

A 10k Ohm potentiometer is used here. The ends of the resistive track are connected to 5V and ground, respectively, and the wiper pin is connected to the A0 analog input pin of the Arduino UNO.
If you are also looking to control the direction of the motor in addition to controlling the speed, you can check out our alternative project that uses the L293D to control the DC Motor.
Strip the ends of the insulated wires or wrap the middle of the bare wires with tape. About one inch of exposed wire on each end is needed to get a solid connection. Using wire strippers to cut the correct diameter of the wire is easiest, but using scissors or a knife also works.
Compliance with the system requirements is the basic principle you should follow while selecting components for your DC motor controller schematic. This relates to an MCU, gate drivers necessary to control the transistors, and other components.
