  • Patent number: 10763736
    Abstract: Low frequency power is transmitted over long distances from a surface power supply to a subsea rotating machine, such as a pump or compressor. The low frequency power is used to rotate a motor at low speed. A liquid filled magnetic step-up gear module might be used to increase the low speed motor shaft to a higher speed output shaft that can be used to operate the rotating machine. The magnetic gear module can be configured as a fixed ratio, and the surface power supply can be configured to adjust the power frequency to change the speed of a single subsea rotating machine. In other embodiments, the magnetic gear module can provide a variable gear ratio. A fixed low frequency might be transmitted from the surface and multiple subsea loads can be operated from the same power source, each having their own variable magnetic gear module.

  • Patent number: 10141827
    Abstract: The present invention is a machine in which the repulsion and attraction forces of moving electromagnets are utilized to power a series of linkages that ultimately turn a crank. The motor is controlled by an external computer system which distributes an electric current among the electromagnets. In order to reverse the polarities of the electromagnets, the direction of the current will be rapidly changing. This polarity reverse causes electromagnets to repel and attract. The magnets then oscillate along two swing arms that once swung because of both polarity attraction and repulsion, activate the linkages.

The first and second magnets are arranged such that, in normal operation, the interaction of their respective magnetic fields generates a magnetic force oriented to return said pivoting member portion towards said rotating wheel surface. At least one of the first and second magnets is arranged to permit reversal of its polarity, preferably with the aid of a tool, and thereby of the direction of the magnetic force acting on the pivoting member, said magnetic force then tending to move said pivoting member portion away from said rotating wheel set surface, which makes it easy to handle the various elements of the timepiece mechanism.

  • Patent number: 9878193
    Abstract: A linear displacement damper structure includes a screw shaft, a metallic disk, a screw barrel, a controlling member, and a driving member. The screw shaft is fixed in a position, connected to the metallic disk, and threaded with the screw barrel. The screw barrel is connected to an external device and driven by the external device to perform a linear displacement along a length direction of the screw shaft relative to the screw shaft, so that the screw shaft drives the screw shaft and the metallic shaft. The controlling member has a permanent magnet and is disposed near to the metallic disk, so that the metallic disk generates a magnetic resistance to reduce the rotation speed of the metallic disk. The driving member drives the controlling member to move to change a distance between the controlling member and the metallic disk to adjust the magnitude of the magnetic resistance.

  • Patent number: 9831743
    Abstract: A machine having two co-axial and relatively rotatable rotors and a coaxial stator or housing with respect to which both rotors are rotatable is provided wherein two bearing arrangements mutually support the two rotors with respect to each other and with respect to the stator or housing. One of the bearing arrangements comprises multiple support bearings angularly spaced apart with respect to the axis of rotation of the rotors relative to the stator with the support bearings each having an axle or shaft that is fixed relative to one of the rotors or the stator. Each support bearing cooperates with a raceway provided on a concentric adjacent rotor or stator. The machine may be an electromechanical machine such as a wind turbine in which rotational movement of one of the rotors relative to the other and relative to the stator generates electrical energy.

  • Patent number: 9677564
    Abstract: A magnetic propeller device for an unmanned aerial vehicle (UAV) includes a propeller and a shaft mount that engage with a motor shaft of a UAV. The propeller and shaft mount each have a magnetic element. When both magnetic elements are aligned, the propeller engages the shaft mount by way of a magnetic holding force between the magnetic elements. When a propeller contacts an object and the propeller is displaced, the magnetic elements passively disengage the propeller from the shaft mount due to misalignment of the magnetic elements. Passive disengagement allows the propeller to rotate independently of the motor shaft. Once the UAV moves clear of the object, the magnetic elements can realign, such that the propeller re-engages the shaft mount and resumes rotation with the motor shaft.
