Abstract: The present invention relates to a wheel-on-rail railroad system using propulsion by both a linear motor and a rotary motor capable of being driven at super-high speed using a linear motor propulsion device while not including a large-capacity rotary motor propulsion device for a contact-type railroad car driven in a wheel-on-rail method. In the railroad system, a railroad car (30) is driven in a wheel-on-rail method along a rail (10). The railroad system includes: a rotary motor driving unit (110) which is included in the railroad car (30) and receives power to drive the wheels of the railroad car and provide propulsion force from an electric car line (20); a field magnet unit (210) which is placed in the lower part of the railroad car (30); and an armature unit which is placed on the ground along the rail (10), generates a movable magnetic field, and provides propulsion force to the railroad car (30) through electromagnetic interaction with the field magnet unit (210). Since the propulsion force of the railroad car (30) is provided by operation of the motor driving unit (110) during a low-speed driving period, while during a high-speed driving period, the propulsion of the railroad car (30) is provided by electromagnetic force of the field magnet unit (210) and the armature unit (220), the railroad car is able to operate on a normal low-speed track of the existing electric car line method as well as at high speed and reduce abrasion of the wheels during super-high speed driving since the volume or weight of a rotary motor propulsion device to be loaded on the railroad car can be reduced compared to a normal high-speed railroad car.

Abstract: Disclosed is a generator using movement of magnets. The generator includes: a container member which has a storage space defined by a cylindrical inner wall; a plurality of magnets which are stored in the storage space of the container member to be movable in the longitudinal direction of the container member; and a coil which is wound around the circumference of the container member. Electricity is generated when the magnets move in the storage space of the container member. In addition, by arranging the magnets in a spherical shape, frictional resistance is minimized. Furthermore, the magnets are arranged in a way that attractive force is applied between each other or are grouped in a way that repulsive force is applied between each other.
