Semicon Media is a unique collection of on-line media, focused purely on the Electronics Community across the globe. With a perfectly blended team of Engineers and Journalists, we demystify electronics and its related technologies by providing high value content to our readers.
Motor power relies on the current supplied by the power source. Thus, a low-power BDC motor needs a low current controller and vice versa. A high current DC motor controller typically uses a switching regulator.
Figure 3: The changing resultant flux continually pulls the rotor magnet, causing the rotor to turn.
With some viable alternatives available now, it’s becoming hard for a BDC motor to stay competitive in high-power electronics.
In the circuit, the slider of the 50K potentiometer is connected to analog input pin A0 of the arduino. The LED is connected at digital pin 12 of the arduino. R1 is a current limiting resistor.
When applied to the rotor, the electric current generates an electromagnetic field and makes the armature rotate. The similar poles of the field around the stator and rotor repel each other, which causes a unidirectional motion.
Prepare the power supply. If using a power pack, install the batteries so the + and - sides are facing the correct directions in the housing. If it can be done, keep the power supply off for now.
If this causes many problems, a switch may be installed between these components to shut off the circuit when needed. Once both ends of the wire are connected, the circuit will be ready.
It is an efficient method of speed control of DC motor. When two or more similar series motors are employed in pairs, speed control can be achieved by combining the series resistance with motors in series and parallel connections.

we have plane to develop an Inveter using PWM principle, please assist me to develop it with your much needed ideas.
Applying current when the rotor position is unknown may cause the rotor to turn in the wrong direction. The use of sensors prevents this problem.
There are several ways to generate the PWM signal for the motor, but in this tutorial we will use the 555 timer. Here’s a schematic of the circuit:
