Abstract: A disc motor uses first, second magnetic components and third, fourth magnetic components of first, second magnetic disc set of a magnetic set to carry out magnetization in the motion direction, a coil of a coil set of an induction set is arranged perpendicularly to the motion direction, so as to form a four magneto-mechanical force effect; poles of the first, second magnetic components and the third, fourth magnetic component of the first, second magnetic disc sets are arranged oppositely to each other if they are different in polarity and adjacently to each other if they are the same in polarity; with the switching of forward reverse circuit power supplies of an induction switch circuit, magnetic resistant force can be avoided, the whole motion process is magnetically assisted, input power can be reduced effectively, and output power is increased.

Abstract: The electric motor includes at least two opposing magnet sets, at least a coil assembly, and a detection switch circuit. Each magnet set includes at least a magnet whose poles are arranged perpendicular to the movement of the magnet. The magnets in a same magnet set are stacked and have poles on a same side of reversed polarities. Opposing magnets from neighboring magnet sets have facing poles of a same polarity. The coil assembly is disposed between neighboring magnet sets, and axially parallel to an alignment direction between the facing poles of opposing magnets. Each coil assembly includes a magnetizer wrapped in a winding. Yokes are extended from two ends of the magnetizer towards opposite directions and a specific distance is between the yokes' centers. Together with the detection switch circuit's switching between positive and negative power supplies, the electric motor effectively reduces input power, and increases output power.

Abstract: A coaxial electromagnetic apparatus formed of at least one magnetic disk and at least one coil disk synchronously and relatively movable and staggered at intervals. The magnetic disk and the coil disk are respectively provided with at least one power-driven module and at least one power generation module. The power-driven modules are provided at the outermost diameters of the magnetic disk and the coil disk. The power generation modules are provided at the innermost diameters of the magnetic disk and the coil disk. A rotation speed of the magnetic disk is increased due to torque amplification and good magnetic current management of the power-driven modules, thereby achieving low power consumption and large thrust of the power-driven modules. The power generation modules generate high cutting frequency to increase power generated and meet the requirement for supplying power to the power-driven modules, thereby achieving autonomous power generation and a self-propelled motor.
