  • Patent number: 9985496
    Abstract: The invention relates generally to a step actuator, in which a lead screw coupled with a screw thread formed in a nut member is installed in a rotor magnet and moves back and forth in an axial direction responding to a rotation of the rotor to transmit power in an axial direction. A cylindrical bearing for rotatably supporting the nut member is disposed at an upper part of the nut member and integrally formed therewith, to fundamentally remove a gap in the axial direction in the coupled area between the cylindrical bearing and the nut member, thereby significantly reducing the feeding error of a rotator in the axial direction when the lead screw moves back and forth in the axial direction, and reducing the number of parts to be assembled to lower the material cost and the labor cost for assembly.

  • Patent number: 9876407
    Abstract: A motor includes two magnetically coupled, coaxially-nested Halbach cylinder rotors, one of which passes through a toroidal series of at least two stator coils while the other is attached to an axle or other means of transferring mechanical power. An embodiment is described comprising an additional third Halbach cylinder rotor in which a circumferential arrangement of permanent magnets is mounted rotatably and proximally outside the stator coils, coaxial with the stator coils. Adjacent stator coils are configured so as to produce opposing magnetic fields upon energizing of the motor. Alternating the current to the stator coils induces movement in the rotor. Commutation can occur brushlessly, or the motor can be configured to function without commutation by varying the frequency of the alternating current, and can be configured to operate by either DC or AC current. Alternatively, the rotor may be driven to generate an electric current in the stator.

  • Patent number: 8492936
    Abstract: A rotational energy harvesting apparatus includes a rotor of magnets and a ring of linear-based kinetic energy harvesters. The rotor of magnets is fixed to a rotational source and is caused to sweep past the linear-based kinetic energy harvesters. The rotating magnets compel kinetic energy to be induced in the linear-based kinetic energy harvesters. The kinetic energy is converted into electrical energy.

  • Publication number: 20130154402
    Abstract: The invention relates to an actuating drive for a motor vehicle. It is an object of the invention to provide a further developed actuating drive. It is sought in particular for the actuating drive, in one embodiment, to have a small installation space and/or to be protected against the infiltration of dust and moisture. To achieve the object, the actuating drive comprises a drive, for example an electric motor for a drive wheel with an internal thread. The external thread of a spindle extends into the internal thread. By correspondingly rotating the wheel, an end of the spindle can be moved out of a housing of the actuating drive proceeding from a retracted state. Proceeding from the deployed state, the end of the spindle can be moved in the direction of the housing by correspondingly rotating the wheel in the opposite direction. Furthermore, in one embodiment, the actuating drive comprises an emergency unlocking device.

  • Patent number: 8448540
    Abstract: An assembling mechanism of a self-locking linear actuator includes a gearbox, a one-piece rear retainer seat and a casing. The gearbox is composed of two half pieces, which are mated with each other for accommodating and locating a transmission mechanism of the actuator. The rear retainer seat is fixedly held in the gearbox for supporting a bearing of a threaded rod of the transmission mechanism and bearing the stress from the threaded rod. The contact faces of the rear retainer seat and the gearbox are regular polygonal to facilitate adjustment of fixing angle of the rear retainer seat. The casing is composed of two half casings, which are mated with each other to accommodate the transmission mechanism, the gearbox and the rear retainer seat. The mating faces of the half casings are parallel to the axis of the output shaft of a motor to facilitate connection operation of the casing.

  • Publication number: 20130099601
    Abstract: A driving device includes an alternating magnetic field producing member, a piston member and a crankshaft member. The alternating magnetic field producing member is for producing an alternating magnetic field. The piston member is adapted such that an eddy current is produced therein by an alternating magnetic field produced by the alternating magnetic field producing member, and is movable by a repulsive force between a magnetic field produced by the eddy current and the alternating magnetic field. The crankshaft member is connected to the piston member and can convert the movement of the piston member into a rotational motion. The driving device that can obtain driving force in an environmentally friendly and efficient manner can thus be provided.

  • Patent number: 8405256
    Abstract: A wireless resonant micro-actuator for untethered micro-robots. The wireless resonant micro-actuator includes at least two magnetic bodies that are resiliently connected to one another by a resilient member to form a spring-mass system. A magnetic field generator generates a pulsating or oscillating external magnetic field that creates a magnetic force between the at least two magnetic bodies. The at least two magnetic bodies are capable of being mechanically oscillated to resonance with respect to one another. A converter converts the oscillatory motion of the at least two magnetic bodies to create useful motion.

  • Publication number: 20130038145
    Abstract: A drive device which provides an electromagnetic impact and a movement mechanism using the drive device to achieve a reciprocating movement with a compact and simple configuration. A drive device provides an impact to an object-to-be-moved supported by a friction surface and moves the object-to-be-moved, and includes an electromagnetic coil, a permanent magnet, a stopper, and a control device which controls the electromagnetic coil. The permanent magnet relatively moves to the electromagnetic coil by an action caused by an electrical current supply to the electromagnetic coil. When the electrical current is supplied to the electromagnetic coil, the permanent magnet collides with the electromagnetic coil or the stopper, which forms the collided-body, and generates the impact. The impact can be generated in any direction, then a reciprocating movement of the object-to-be-moved can be achieved.

  • Patent number: 8362660
    Abstract: An electric generator device includes a magnetic stator assembly, opposed coils, and a rotary-to-linear converter (e.g., cam). The coils are configured to reciprocate relative to the magnetic stator assembly or to linearly translate in a common direction relative to the magnetic stator assembly. The coils are coupled to the cam and, upon rotary or linear motion of the cam, reciprocate or linearly translate relative to the magnetic stator assembly. The reciprocation or linear translation of the coils creates an electric current flowing through the coils, which may then be harvested.

  • Publication number: 20130011260
    Abstract: A vibration reduction device according to the present invention includes: an elastic body; a dynamic mass; and a controllable mass. The dynamic mass is supported by an object of vibration reduction through the elastic body. The actuator causes the controllable mass to move with respect to the dynamic mass. Such a vibration reduction device can vary the frequency and the amplitude at which the dynamic mass vibrates with respect to the object of vibration reduction by causing the controllable mass to move appropriately with respect to the dynamic mass, thereby enabling the vibration of the object of vibration reduction to be reduced more reliably. In addition, such a vibration reduction device can reduce vibration of a certain frequency of the object of vibration reduction even when the controllable mass is fixed with respect to the dynamic mass.
