A direct current (DC) motor is the oldest type of electrical motor that has gained widespread use in a variety of electronic devices and equipment. DC motors have different arrangements and operation peculiarities.

Semicon Media is a unique collection of online 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.

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.

So if i were to modify the motor speed control using arduino to run 2x motors (in parallel) that ran @ 12v .4A on one pwm channel, what would the capacitor rating and transistor rating have to be? would an NTE293 npn transistor be sufficent? And if so, does R1 have to be changed at all?

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.

We cannot complete your request due to a technical difficulty. You may return to the previous page or

The speed of rotation can be controlled by controlling the rate at which the phases change. We use the name “120-degree conducting control” to the seis-mode control method described here.

PWM control is a very commonly used method for controlling the power across loads. This method is very easy to implement and has high efficiency. PWM signal is essentially a high frequency square wave ( typically greater than 1KHz).

1  Here we will show how you can control a DC motor using the Arduino PWM build in capability. We will be using a general purpose transistor to amplify the output signal from the Arduino PWM pin. Also we will be using diode and decoupling capacitor for Em excesso protection and reducing noise created by the DC motor.

Here’s the final appearance of the board and what’s left now is to connect a DC motor and a suitable power supply for it.

When it comes to speed controls, we believe in delivering a good quality product with our every day low prices. You won't find plastic cases or low quality parts used in the construction of our units, nor will you find non genuine components used to save cost.

Here’s a basic circuit of the 555 Timer operating in an astable mode and we can notice that the output is HIGH when the capacitor C1 is charging through the resistors R1 and R2.

The OMDC-MD Series is a compact, programmable DC speed control with digital closed loop feedback and LED display for DC motors rated to 2 horsepower. An on-board microprocessor with non-volatile memory, coupled with sophisticated internal software, makes the OMDC-MD series speed control the ultimate value in accuracy and control.

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.
