Abstract: A power conversion apparatus includes: a rotating electric machine that has a winding; an inverter that has a series-connection body of an upper arm switch and a lower arm switch; and a capacitor that is connected in parallel to the series-connection body. The power conversion apparatus includes: a connection path that, in a first storage battery and a second storage battery that are connected in series, electrically connects the winding with both a negative-electrode side of the first storage battery and a positive-electrode side of the second storage battery; and a control unit that controls switching of the upper arm switch and the lower arm switch such that a current flows between the first storage battery and the second storage battery through the inverter, the winding, and the connection path.

Abstract: A system can include an axial field rotary energy device with an axis of rotation and a rotor coaxial with the axis and having a shaft, bearings, rotor disks that are coaxial and permanent magnets on each rotor disk. A printed circuit board (PCB) stator is located between the rotor disks to define an air gap on each side of the PCB stator. An enclosure has two enclosure sections with an inspection port. Bearing caps and bearings are mounted to the rotor. A variable frequency drive (VFD) assembly is coupled to the axial field rotary energy device. The VFD has a flexible conduit that extends between the VFD housing and the axial field rotary energy device. The flexible conduit can adapt to different sizes of axial field rotary energy devices.

Abstract: A base portion of a magnet holder attached to a rotor core of a rotor has a press-fit pin press-fitted into a press-fit hole provided at an end surface of the rotor core. An arm portion of the magnet holder has a holder rib which protrudes inward in the radial direction of an output shaft and of which one end surface in the circumferential direction serves as a pressing surface, and a come-off prevention protrusion inserted into an insertion groove provided at an outer circumferential surface of the rotor core. Magnets are located between the rotor core and the magnet holders, one end surface in the circumferential direction of each magnet contacts with the pressing surface, and another end surface contacts with a core rib protruding from the rotor core.

Abstract: An optical system is provided, including a movable part, a fixed part, a first sensor, a second sensor, and a control unit, wherein an optical element is disposed on the movable part. The first and second sensors detect the movement of the movable part relative to the fixed part in a first dimension and a second dimension, and thus they respectively generate a first sensing value and a second sensing value. The control unit generates an error value according to the first sensing value and an error curve, and then calibrates the second sensing value according to the error value.

Abstract: A drive includes a dynamoelectric rotational machine, an electronic add-on part, and a fan unit arranged axially behind one another. The fan unit generates a cooling air flow and is embodied as a two-zone fan having axial fan elements which define a first zone to generate essentially an axial air flow and include an articulated joint with an elastic region with sufficient restoring force, and radial fan blades which define a second zone that radially adjoins the first zone and generate essentially a radial air flow. Free spaces are provided at least between a housing arrangement and the fan unit and/or between the housing arrangement and a bearing shield of the dynamoelectric rotational machine and/or between the housing arrangement and/or a shaft of the dynamoelectric rotational machine, with the free spaces being acted upon during operation of the fan unit by the cooling air flow and a Venturi effect.

Abstract: A linear motor conveyor system having a moving element comprising a first and a second magnetic element on opposite sides; a first track comprising a first linear motor configured to generate a dynamic magnetic field which acts on the first magnetic element to provide a first dynamic lateral force and a first dynamic longitudinal force; a second track with a transfer region positioned adjacent to the first track, the second track configured to generate a magnetic field that acts on the second magnetic element to provide a second lateral force; and a controller to control the first linear motor such that the first dynamic lateral force is configured to bias the moving element toward the first linear motor until the moving element reaches a switch point in the transfer region, after which the dynamic lateral forces are selectively adjusted to bias the moving element toward the first or second track.

Abstract: An automatic descent control device includes a line configured to be attached to a load. A line system retracts slack from the line when the line is not loaded and extends the line when the line is loaded. At least one braking system provides a braking force when the line is loaded so as to control extension of the line and a descent rate of the load. The at least one braking system is operable in at least two configurations, a first configuration that the at least one braking system lowers the load at a first descent rate, and a second configuration that the at least one braking system lowers or locks the load at a second descent rate. The load being a constant and the first descent rate is greater than the second descent rate.
