Climate Dependent Automatic Fan Speed Controller Circuit
The following circuit of a temperature or climate controlled automatic fan speed regulator circuit was requested by one of the followers of this blog Mr.Anil Kumar. I have explained more about the proposed design. The Design As can be seen in the given diagram, a very simple concept has been implemented in the proposed design of a climate controlled […]
BLDC Ceiling Fan Circuit for Power Saving
Within the next few years we may find all conventional capacitor-start type of ceiling fans getting replaced with BLDC ceiling fan circuits, since the concept allows the operation to be extremely efficient and save power by more than 50%. Replacing Capacitor Start Fan with BLDC Fan Just as the traditional incandescent lamps today are almost […]
Make this Simple Washing Machine System
In this post I have explained how to make a simple washing machine using a single motor and a cam shaft mechanism, cheaply. The Concept Washing machines are costly devices which may not be affordable for a section of the population and also to villagers who even might not have an easy access to these […]
Simple Ceiling Fan Regulator Circuit
A simple electronic ceiling fan regulator circuit using a triac and a diac is a common type of circuit which is used to control the speed of a ceiling fan. This circuit basically works using phase control principle, in which the voltage supplied to the fan motor is varied by controlling the firing angle of […]
Motor Protection Circuits – Over Voltage, Over Heat, Over Current
In this post I have explained a few DC motor protection circuit from harmful conditions like over voltage and under voltage situations, over current, overload etc.. DC motor failures are commonly experienced by many of the users, especially in places where the relevant motor is run for many hours a day. Replacing motor parts or […]
