A solenoid engine is a curiosity of the electrical world. By all measures, using electricity to rotate something can be done almost any other way with greater efficiency and less hassle.

[Emiel] aka [The Practical Engineer] makes all kinds of fun projects in his fully-featured shop, and one of his tangents has been building a series of solenoid engines. These engines mimic the ...

Principal component analysis (PCA) is a mathematical algorithm that reduces the dimensionality of the data while retaining most of the variation in the data set 1. It accomplishes this reduction ...

Rotary solenoids are electromechanical devices that convert axial motion into rotary strokes. These transducers have a higher starting force (torque) than linear solenoids, and are more resistant to ...

Linear solenoids convert electrical energy into mechanical power via a plunger with an axial stroke in either a push or pull action. These transducers consist of a coil of wire, sometimes wrapped ...
