The mechanical part can be modeled as an inertial rotor with friction. The DC motor is conceptually modeled as in Figure 1 with the parameters given in Table 1.

We can also notice that in this configuration the period of one cycle, thus the frequency, will always be the same, because the Completa resistance, while charging and discharging, will remain the same.

A controller of a brushed DC motor manages the speed and torque of the motor by regulating the current and voltage injected into it. The major design and working principles of BDC motor controllers can differ between their types.

Since the output will be high when the capacitor is charging and is low when the capacitor is discharging, we get a difference in high output and low output times, and so the PWM.

Connect the left pin of the potentiometer to the drain pin of the mosfet, the middle pin to the gate pin of the mosfet, and the right pin to the negative wire of the 9V battery clip.

In a DC motor, a shaft is connected to a wire coil that has current running through it. There are also circular magnets surrounding the wire coil. When the motor is supplied power, the current flows through the wire coil, and the magnetic field causes the coil to rotate and turn the shaft.

You can find a DC motor in many electronic appliances around you, including in an electric toothbrush, a washing machine, a printer, and a car. A motor controller ensures the efficient and safe operation of the motors used in these appliances.

Implementing a feedback control system, we faced a problem with the microcontroller that couldn’t process the encoder signal outputs.

Hey, I’ve updated the article and include a link to the EasyEDA project file. Please check the section of the PCB design above and you will find it.

If you need a controller for a BDC motor, you can use an off-the-shelf device that fully meets your requirements. Or you can build your own solution with a tailor-made circuit design and custom firmware.

In a DC motor, different speed controls can be achieved and hence they are used for many adjustable speed drives. The different mechanisms of speed control can be deduced from the speed equation of a DC motor.

Table 1 lists the typical types of sensors used in these motors. Different types sensors are used for different methods of control. Hall elements, with signal inputs spaced at 60º, are best for motors that use 120-degree conductingcontrol—where all that is necessary is to determine which phase to energize.

PWM stands for Pulse Width Modulation and is a technique of generating signal with different width of high and low pulses. The act of changing the pulse width for low and high is called modulation. When such PWM signal(series of different width pulses) is supplied to a DC motor, we can increase or decrease the amount of power supplied to the motor.

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.
