  • Patent number: 8786151
    Abstract: A rotor-stator structure including plural bumper elements that may employ synthetic sliding bearing surfaces, mounted to the stator, and designed to contact a machined surface on the rotor if generator structural deflection occurs during operation. During normal operation, the bearing surface is not in contact with the machine rotor. If extreme loads are imposed on the rotor or stator structures, or other issue like bearing failure, causes the air gap to close, the bumper elements will “touch down” on a machined surface on the rotor to maintain a minimum air gap.

  • Patent number: 8598757
    Abstract: A magnetic-controlled actuator (100) with an auto-locking function for joints of a manipulation arm mainly includes an inner-layer stator (10), an inner-layer mover (20), an outer-layer mover (30), an outer-layer stator (40), and a fixing shaft (50). The inner-layer mover (20), the outer-layer mover (30), and the outer-layer stator (40) have a plurality of permanent magnets, respectively. The fixed shaft (50) simultaneously penetrates through the inner-layer stator (10), the inner-layer mover (20), the outer-layer mover (30), and the outer-layer stator (40) forming a coaxial arrangement. The inner-layer mover (20) rotates relatively to the inner-layer stator (10) to output power from the actuator (100). Therefore, a cogging effect, which is produced due to interaction of the permanent magnets between the outer-layer mover (30) and the outer-layer stator (40), is automatically produces a high cogging torque for the actuator (100).

  • Patent number: 8066480
    Abstract: A high volume low speed (HVLS) fan provides improved air circulation and thermal control in a building by incorporating composite fan blades pivotable to both positive and negative pitch angles. The blades are molded of polymer material over a metal tube core for strength and ease of attachment to the fan hub, and have a symmetrical airfoil shape to produce an efficient bi-directional conical airflow. The fan includes a control unit providing manual and automated intelligent control over blade angle and rotational speed, as well as startup with approximately zero blade angle for more economical power consumption and less motor wear. The fan structure and mounting system allows the fan to be installed at an optimal height inside a variety of buildings to provide increased efficiency of air destratification and air mixing. An array of multiple HVLS fans with alternating directions of airflow can further increase efficiency of air movement.

    Abstract: A permanent magnet rotor of a generator is used to excite a electromagnet stator to generate electric power for the generator and to control a disengagement mechanism whereby the generator can disengage from an accessory, such as a gear box drive shaft, when the generator is not working properly. The permanent magnet is affixed to an outer ball screw which normally rotates with an inner ball screw that is operatively engaged to the accessory. An increased load to the electromagnet stator slows or stops rotation of the permanent magnet rotor and outer ball screw, causing the inner ball screw to move axially from the outer ball screw and away from an accessory and toward a re-settable lock.

    Abstract: A magnetostrictive motor is provided with a pair of clutch devices on a rotor shaft through which electrical energy from electromagnetic rings on a tubular reactor is converted into forces transferred to the rotor shaft within the reactor under selective control of magnetostrictors and clutches within the tubular reactor to either accelerate or decelerate motion imparted by such forces to the rotor shaft for change of rotor speed magnitude and direction.

  • Patent number: 6714733
    Abstract: A step motor is composed of a rotor, first and second stators, and a magnetic member. The rotor is rotatably supported and comprised of a magnet having magnetic poles magnetized in four angular sections. The first stator has a pair of counter poles disposed in opposed relation to the magnet and a coil wound around the first stator. The second stator has another pair of counter poles disposed in opposed relation to the magnet and another coil wound around the second stator. The second stator is opposite to the first stator with respect to the rotor such that the counter poles of the first and second stators surround the rotor to stepwise rotate the rotor in response to electric pulses applied to the coils of the first and second stators. The magnetic member has a pair of interpoles positioned in a middle of the first and second stators in opposed relation to the rotor such as to stabilize a rest position of the rotor, which is held when the electric pulse is not applied to the coils.

  • Publication number: 20040055843
    Abstract: In a generator and motor system of the present invention, when an engine is running, a rotational apparatus is driven by power from the engine and a motor generator is driven to generate power, and when the engine is stopped, the motor generator is put in motion by power supply from the outside to drive the rotational apparatus. The system includes a mechanical power transmission mechanism for transmitting power of the engine to the motor generator and the rotational apparatus. The power transmission mechanism permits power transmission from the engine to the motor generator and the rotational apparatus, and prevents power transmission from the motor generator to the engine.

  • Publication number: 20030227227
    Abstract: A dual function motor/generator includes a rechargeable battery, a mode switching device, a dual function rotor/stator structure, at least two transmission devices and a clutch device for selecting one of the two transmission devices depending on whether a motor or generator mode is selected. When the dual function motor/generator is used as a motor, power is supplied from the rechargeable battery controlled by the mode switching device to a driven load through the rotor/stator structure and one of the transmission devices, and when used as a generator, the battery is recharged by applying an external force to the load such that the load drives the other transmission device to rotate the rotor in a direction opposite a direction of rotation of the rotor in the motor mode, and thereby induce an electric current in the rotor/stator structure to recharge the battery.

  • Patent number: 6617727
    Abstract: A housing of a compressor supports a rotary shaft. The rotary shaft is coupled to a pulley with a pulley one-way clutch and is coupled to a rotor of an electric motor with a motor one-way clutch. The pulley is supported by the housing with a pulley bearing. The electric motor overlaps a power transmission portion in the axial direction of the rotary shaft. At least two of the bearing, the pulley one-way clutch, the motor one-way clutch, and a brush device of the electric motor overlap each other in the axial direction of the rotary shaft. As a result, the size of the compressor is reduced in the axial direction of the rotary shaft.

  • Publication number: 20030048014
    Abstract: In an engine starter of the present invention, a driving shaft to output a rotating force and a crankshaft of an engine are linked continuously. The engine starter comprises a one-way clutch to prevent an overrun of an armature after the engine starts. In the one-way clutch, a connecting rotation number in which an inner ring and an outer ring change from a disconnected state to a connected state in a decreasing process of engine revolutions is set above a lower limit of the engine revolutions above which the engine under suspension of the fuel supply is able to get restarted by itself by resuming of fuel supply. Therefore, the engine is always able to get restarted quickly even in a low-rotation range.
