20090009157 | SYSTEM AND METHOD FOR MEASURING ENERGY IN MAGNETIC INTERACTIONS - An apparatus and method is provided for measuring magnetic force response time due to the magnetic viscosity of materials and for measuring total energy exchanged due to relative motion of magnetic materials. Voltage and current versus time through an electromagnet is measured and recorded. Corresponding force versus time is measured for magnetic forces applied to a material under test in response to energizing the electromagnet to determine effects of magnetic viscosity of the material under test. A test system is also provided for measuring energy exchanged due to the relative motion of magnetic materials. Absolute values of transferred mechanical energy and electrical energy are combined to determine the total energy exchanged by interaction of a permanent magnet and an electromagnet. | 01-08-2009 |
20090128135 | MAGNET SCANNER - A magnet scanning device uses a helical scanning technique to scan a cylindrical magnet along a helical path on a cylindrical surface that corresponds to the cylindrical magnet. Based on the magnetic field profile, the device may detect any unacceptable irregularities in the magnetic field and identify a location of the cylindrical magnet associated with the irregularity. | 05-21-2009 |
20100033166 | Method For Estimating The Magnetization Level Of One Or More Permanent Magnets Established In One Or More Permanent Magnet Rotors Of A Wind Turbine Generator And Wind Turbine - A method for estimating the magnetization level of one or more permanent magnets established in one or more permanent magnet rotors of a wind turbine generator includes the steps of: establishing one or more magnetization sensors at the stator of the generator, connecting the one or more magnetization sensors to a measuring mechanism, processing measured data in the measuring mechanism, and establishing values of magnetization. Furthermore the invention also relates to a wind turbine. | 02-11-2010 |
20100060266 | MAGNETIC FIELD ANALYSIS METHOD, MAGNETIZATION ANALYSIS DEVICE, AND RECORDING MEDIUM WITH COMPUTER PROGRAM - It is possible to perform accurate magnetization analysis by considering the magnetic state of an incomplete magnetic region. A magnetization analysis device performs magnetization analysis by using a magnetizer parameter associated with a magnetizer and a magnet parameter associated with a magnet material so as to calculate a magnetization magnetic field applied to respective portions of the magnet material (S | 03-11-2010 |
20100301839 | MAGNETIC ANCHORAGE EQUIPMENT WITH A SELF-TEST UNIT - The present invention relates to magnetic anchorage equipment comprising a frame able to contain a plurality of polar units, each of the plurality of polar units having a ferromagnetic polar element which identifies an anchorage surface and a self-testing unit for checking the magnetic equipment. The magnetic anchorage equipment is characterized in that the self-testing unit for checking the magnetic equipment is at least partly integrated in the frame. | 12-02-2010 |
20120306478 | BEARING CHECK FIXTURE - A hand-held check fixture to indicate excessive play in a pitch change link ball joint is provided. The check fixture can include a first member for attachment to a first portion of the pitch change link, a second member for attachment to a second portion of the pitch change link, and a gage to indicate movement of the first member relative to the second member. The gage is adapted to indicate the clearance between a pitch change link ball bearing and a pitch change link knuckle in the axial direction and/or in the radial direction. The check fixture can assist in evaluating the flightworthiness of each pitch change link on a rotor assembly with relative ease and without requiring the complete removal of each pitch change link from the rotor assembly. | 12-06-2012 |
