Electromagnetic rotation experiment of Faraday, ca. 1821 [2] Working principle of a homopolar motor: due to movement of negative charges from center towards rim of the disk, a Lorentz force F L is created which brings the entire disk into rotation. The homopolar motor was the first electrical motor to be built.
Makeblock (Chinese: 童心制物) is a private Chinese technology company with headquarters in Shenzhen, China.It develops Arduino-based hardware, robotics hardware, and Scratch-based software for the purpose of providing educational tools for learning.
Lavet-type stepping motor of a quartz clock. A black rotor sprocket provides the mechanical output. The Lavet-type stepping motor has widespread use as a drive in electro-mechanical clocks [1] and is a special kind of single-phase stepping motor. Both analog and stepped-movement quartz clocks use the Lavet-type stepping motor (see Quartz clock).
A stepper motor, also known as step motor or stepping motor, [1] is a brushless DC electric motor that rotates in a series of small and discrete angular steps. [2] Stepper motors can be set to any given step position without needing a position sensor for feedback. The step position can be rapidly increased or decreased to create continuous ...

Some small businesses build conversion kits for engine swaps, such as the Fiat Twin cam into a Morris Minor or similar. A common anecdote [citation needed] among tuners in the United States is that the easiest way to make a car faster is to drop in a more powerful engine, such as the General Motors small-block engine as used in the Corvette.
