3 Phase Induction Motor Speed Controller Circuit
In this post I have explained the making of a simple 3 phase induction motor speed controller circuit, which can be also applied for a single phase induction motor or literally for any type of AC motor. When it comes to controlling the speed of induction motors, normally matrix converters are employed, involving many complex […]
How to Generate Electricity from Road Speed Breakers
Free Energy is available all around us in a variety of different forms, it just needs to be appropriately harnessed and used. One such example is our modern streets and roads where thousands of heavy and small vehicles pass everyday non-stop. Electricity from Roads The amount of energy transferred across the roads by these vehicles […]
Vehicle Speed Limit Alarm Circuit
In our previous articles we have learned comprehensively regarding the ICs LM2907/LM2917 which are fundamentally frequency to voltage converter ICs, and are ideally applicable in all such relevant fields. Here we see how the same chip can be applied for making a vehicle speed limit alarm circuit. Using a Single IC for Speed Detection As […]
Pedal Speed Controller Circuit for Electric Vehicles
In this part of the article I have explained about an innovative method of converting pedal press mechanism in electric vehicles into a correspondingly varying electrical signal, which may be further used for processing the speed control of the vehicle. The explained concept will work like an electronic accelerator, which will increase the vehicle speed […]
Speed Dependent Brake Light Circuit
In this post I have explained an innovative brake light circuit using speed detection of the vehicle which could be a motorcycle. The circuit implements an advanced brake light switch ON ensuring a much safer riding experience for the user. The idea was requested by Mr. Rayan. Circuit Objectives and Requirements I have an idea, […]
