H-bridge DC motor controller circuit. BDC motor controller circuit design depends on the type of signal, power regulation, control system, and other features. You can choose among various options based on your technical specifications and budget limits. 

The torque and speed vary with load as indicated by this torque-speed curve. Looking at the graph below, let’s consider a motor rotating at speed ω0 with torque T0.

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.

AC motors are driven by alternating current, and stepper motors are driven by pulses of electric power. DC motors on the other hand are powered by direct current, and have the following features.

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.

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.

By adjusting duty cycles, you can control the motor speed. A switching regulator has higher efficiency and less power loss, and PWM is widely used in speed controller design for DC motors.

Test the circuit. The DC motor should now be spinning if all components are securely connected. The resistance provided by the resistor(s) determines the speed the motor will run. If the motor is not running, check all the connections to make sure the circuit is securely connected. If the motor still doesn't run, check that the battery is not dead by connecting it directly to the motor and replace or recharge if dead.

I hope you enjoyed this tutorial and learned something new. Feel free to ask any question in the comments section below.

By controlling the current into all three phases, resultant flux magnitude and direction can be controlled more precisely that with 120-degree conducting control, so as to achieve smoother rotation. Resultant flux is no longer limited to six discrete directions.

In this section of the tutorial DC Motor Speed Control using Arduino UNO, I am going to explain you about designing as well as a detailed description of the designed algorithm. I will tell you about the entire algorithm in step by step procedure.

The intended use of a motor controller is to manage the performance of an electrical motor. Irrespective of the motor type, this electronic device can fulfill the following functions:

PWM is a method through which we can generate variable voltage by turning on and off the power that’s going to the electronic device at a fast rate.

The switch is to change the direction of rotation of motor. The capacitor here must not of a fixed value; the user can experiment with it for a right one.
