If you are searching for projects to keep you busy over the next few weeks, you may be interested in this awesome miniature V8 Solenoid Engine, which is capable of generating plenty of power. Created by YouTube’s The Practical Engineer, this small solenoid engine uses 40 meters of 0.4mm wire per spool. The maximum revolutions per minute (RPM) measured is 1,000, according to its creator. See the solenoid engine in action in the video below.
“In the past, I have made a 1-cylinder solenoid engine and a V4 solenoid engine. They turned out really cool, but today I’m going to improve on it by making a V8 solenoid engine. To improve it, I not only double the number of solenoids, I’m also going to make the crankshaft on my CNC mill and use infrared sensors for the switching of the solenoids.”
Understanding Solenoid Engines
Solenoid engines are fascinating devices that convert electrical energy into mechanical motion using solenoids. A solenoid is a coil of wire that generates a magnetic field when an electric current passes through it. In a solenoid engine, this magnetic field is used to move a piston or other mechanical components, creating motion. The V8 solenoid engine, as demonstrated by The Practical Engineer, is a more complex version of this concept, featuring eight solenoids arranged in a V configuration, similar to a traditional V8 internal combustion engine.
The use of solenoids in engines is not just a hobbyist’s pursuit; it has practical applications in various fields. For example, solenoid engines can be used in educational settings to teach principles of electromagnetism and mechanics. They are also used in some industrial applications where precise control of motion is required.
Building the V8 Solenoid Engine
The construction of a V8 solenoid engine involves several intricate steps. The Practical Engineer’s approach includes winding 40 meters of 0.4mm wire for each solenoid, ensuring that the coils are tightly wound to maximize the magnetic field strength. The crankshaft, a critical component of the engine, is machined using a CNC mill, which allows for precise shaping and alignment.
One of the innovative aspects of this project is the use of infrared sensors for switching the solenoids. Traditional solenoid engines often use mechanical switches, which can wear out over time and reduce efficiency. Infrared sensors, on the other hand, provide a non-contact method of switching, increasing the engine’s reliability and longevity.
The Practical Engineer’s video provides a detailed walkthrough of the entire building process, from initial design to final assembly. This makes it an excellent resource for anyone interested in replicating the project or understanding the principles behind solenoid engines.
