pwm dc motor speed controller circuit

In the article “PWM DC Motor Speed Controller Circuit” article, we will learn, how to control motor speed using a comparator IC. This circuit has an advantage over a normal motor speed controller using 555 timer IC i.e. it protects MOSFETs from short-circuits. This speed control is accomplished in three phases using two methods: variable switching frequency and variable pulse width modulation. The phases are explained as follows: We will first produce square wave pulses of the necessary frequency i.e. switching frequency. We will create PWM pulses of the required…

motor controller circuit for washing machine using 555

Washing machines have been an important part of our daily life. But, the issues we have to deal with in a few months of using them make it more difficult. Previously, we had already posted the Automatic Washing Machine control circuit. It is because most of the washing machines have a single-phase motor incorporated in the system and the timing and direction of the motor are controlled by an external mechanical switch which gets worn out so easily and is not economical on the other hand. And, the project “Motor…

solder fume extractor circuit

Solder Fumes Extractor Circuit: Soldering in electronics is analogous to fixing a component using glue. It is a general phenomenon in the field of electronics that involves fixing electronic components into a special board called PCB with the help of instruments like soldering iron and electrical solder commonly called ‘Solder wire’. While soldering we all face the problem of toxic fumes. These fumes are of lead solder wire and flux. Combinedly, these fumes are highly toxic if an excess amount is inhaled. To solve this problem, here we designed a…

Temperature Controlled Fan using Arduino

Engineeering Projects
arduino based temperature controlled fan

The project ‘Temperature Controlled Fan using Arduino is simply fabricated around Arduino uno board and temperature sensor LM35. The projects are a good example of embedded systems designed using a closed-looped feedback control system. For proper user interface visual indication we had also used LCD which indicate the temperature as well as the speed of the fan. Circuit Description of Temperature Controlled Fan using Arduino The entire circuit of ‘Temperature Controlled Fan using Arduino’ utilizes very few components, an MCU (Arduino Uno), a temperature sensor (LM35), an LCD, a motor…

Servo motor tester circuit using 555

I believe testing circuits are a must for project geeks since these testers save so much time in debugging circuits. People invest all their efforts and spend so much time completing one project but most of the time they don’t get the desired output. There can be multiple reasons behind this and generally, it is because the components like servo motors are at fault. The project Servo Motor Tester Circuit Using 555 IC was used in the project after isolating it from the project and helping us to detect if…

BLDC motor driver circuit using 555

After the BLDC motor driver circuit, had been introduced, its demand and use have increased past the mid- 20th century. Be it because of its flexibility that it can be converted into small size, or is it because it is much lighter than the conventional dc motor with brushes, the product is in the most preferred list of people. The device demands information about the rotor- position to set the favorable commutation angle. And, for this purpose, a Hall effect sensor is employed in the project. However, doing so can…

author prototype of ac motor speed controller

Here is a simple circuit “AC Motor Speed Controller Circuit Using Microcontroller” which is used to control the speed of AC motor using microcontroller At89c51. The circuit uses the principle of changing the firing angle of TRIAC to control the speed of the motor. Here, in this project, we had to use various switches to control the speed whereas an LED bar graph is used to indicate the speed of the motor. Circuit Description of AC Motor Speed Controller Circuit Using AT89C51 The circuit diagram of the signal phase AC…

mechanical arrangement for the lock

Previously, we have posted light controlled digital fan regulator, with which we can control the speed of the fan remotely from the bed with the help of a torchlight. Now, here is another light-operated project which can also operate remotely from the bed with a torchlight. The group electronics hobbyist at Best Engineering Projects designed and verified a very unique electronic circuit light operated internal door latch with which one can close or open the door of your room remotely.” Check out other security-related projects posted on bestengineeringproject.com Car Lock…

circuit diagram of dc motor controlling using single switch

The various motor control circuit is already available on the internet and this is also not a new idea for the electronics hobbyist. The circuit of the DC Motor Control Circuit, published here is different from another circuit available for motor control because it let you run a DC motor in a clockwise or anti-clockwise direction and stop it using a single switch. DC motor control circuit has also another advantage i.e. for proper operation of the motor this circuit provides a constant voltage. Here we use three LEDs LED1…

water tank motor setup

Many of us use water pumps for drawing water from an underground tank. Whenever the water level in the tank goes low we have to switch ‘off’ the motor and when it reaches a high level we have to switch ‘on’ the motor. The circuit automatic suction tank motor controller given here solves this problem. The truth table for the digital circuit of automatic suction tank motor controller Condition H L Y Remark Empty tank 0 0 0 Water is filled up to ‘L’ 0 1 0 Full tank 1…
