This video is a demonstration of how the magnets placed in a motor rotate another motor with no mechanical transmission.
To the main motor 230 volts there is attached a thick disc of iron and four strong neodymium magnets. In front of the main motor, there is another secondary motor, attached to it there is a very thick disk of aluminium. When the main motor reaches a certain speed, it drags the aluminum disc placed in the dynamo., it transports the aluminium disc inserted in the dynamo.
