The Mendoza motor is the simplest brushless motor. Such an engine needs very little voltage, it works from sanctification, even a simple light bulb is enough for movement. There is no practical application for such a device, but the contemplation of the operation of the levitating engine relaxes and makes you distract from everything.
The creation of the Mendosin motor requires certain knowledge and skills, as well as solar panels and neodymium magnets.
