摘要： A magnetic path closed electric generator includes a base (9), a housing (8), a stator (3), a rotator (5), a rotation shaft (7) and a transmission wheel. A magnetic permeability neck (12) is fixed on the stator; a coil winding (2) on the stator is fixed on the magnetic permeability bracket (1) and hitches outside a magnetic permeability neck; a low magnetic permeability medium (13) is disposed between the magnetic permeability bracket and the magnetic permeability neck. When the rotator rotates, a magnetic body (4) rotates along with it. The magnetic permeability neck is inducted to permeate magnetic and generate electric current with change of flux passing through the coil winding. A magnetic field generated by the electric current in the coil winding passes through the magnetic permeability bracket. The coil winding on the stator and the magnetic body on the rotator form a magnetic line closed loop in their own magnetic field. There is only small magnetic attracting force between the rotator and the stator.

摘要： PROBLEM TO BE SOLVED: To provide a direct-acting generator which prevents a decrease in the quantity of generated power due to magnetic saturation. SOLUTION: This generator is provided with: a fixed yoke 2 and a mobile yoke 3, which reciprocates along the fixed yoke 2, and for the mobile yoke 3, permanent magnets 4, the magnetic poles of whose same polarity face out in opposite directions of reciprocation, are built in both ends in the direction of reciprocation. The fixed yoke 2 includes a yoke 6 for bypass. The yoke 6 has a coil 5, which is wound at right angles to the direction of motion of the mobile yoke 3, an inner sidewall 2a, which covers the side, close to the mobile yoke 3, of the coil 5, and an outer sidewall 3b, which covers the side, far from the mobile yoke 3, of the coil 5. The yoke 6 faces the mobile yoke 3 from the opposite side of the fixed yoke 2, and approaches or breaks from the permanent magnet 4, accompanying the reciprocation of the mobile yoke 3.

摘要： PROBLEM TO BE SOLVED: To provide a generator which can obtain a larger amount of power generation compared with the case that an axially-magnetized magnet is used even if rods of the same lengths are used, and also can generate power by efficiently utilizing vibration energy accompanied by the vertical movement of a variety of vehicle bodies. SOLUTION: A plurality of radial magnets are attached to the reciprocating rods in a shape that the rods and the radial direction perpendicularly cross each other, and power generation coils wound to iron cores are arranged at both sides of the rods and the radial magnets. In this generator, the power generation coils are arranged at external peripheries of the rods and the radial magnets. In the generator, a plurality of the power generation coils are arranged. The rods are arranged so as to reciprocate by utilizing vibration at the traveling of one of vehicles which is selected from a group composed of an automobile, a motorcycle, a bicycle and an electric train.
