A lot of Engineering projects and tutorials for the students to help them in their final year projects and semester projects.
From the above expression, it can be revealed that the speed can be controlled by any one of the following three factors
Note that: I’ve deleted the Automóvel-generated TIM2 initialization function and its parameter. Since our DC Motor library will handle that, we don’t need that function at all.
As an alternative to 120-degree conducting control, we can use sinusoidal control to achieve smoother and quieter operation. With 120-degree conducting control, the motor is controlled by continually cycling through six fixed resultant fluxes.
If both ends of the power supply are touched, the circuit may slightly electrocute you depending on the current being supplied.
This page will show step by step the relationship between speed, torque and drive voltage of a DC motor, and how to control it.

When the speed is to be increased, the two motors are connected in parallel with the starting resistance in series, as shown in figure(b). The starting resistance is gradually cut out when the motor picks up the speed.
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.
In a BDC motor controller, the speed and torque are regulated by changing the power supply with the help of voltage regulators. They can be either a separate system or a part of the controller. For different purposes, engineers can use linear or switching regulators.
Circuit diagram of DC motor speed control using arduino is shown in the figure below. The working principle and program of this circuit is same as that of the LED brightness control. Only difference is that and additional motor driver circuit using a transistor is included in the circuit.
The resistors can be any value but getting the exact speed needed from the motor requires testing with a certain range of resistors. The values of the resistors add up linearly so it is easy to calculate how to increase or decrease the motors speed by simply adding the values together. For example, two 1kΩ resistors wired together will act the same as a 2kΩ resistor.
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.
Substituting the parameter values in Table 1 within Equations (Lfrac di dt + Ri + Kfrac dϕ dt = u) and, (Jfrac d^2ϕ dt^2 +bfrac dϕ dt = Ki) , the DC motor speed model as a system of differential equations is described as:
