Offset Correction in a Digital Integrator for Rotating Coil Measurements
The rotating coil technique is extensively used in high-precision measurements for accelerator magnet testing. One of most relevant error sources is the drift arising from the integrator offset. In this paper, a correction algorithm for the offset drift in digital integrators is presented. Preliminary experimental results for the measurement correction of the main field of a superconducting dip...

متن کاملCalibration of Rotating Coil Arrays for Particle Accelerator Magnet Testing
Synchrotron particle accelerators are mainly composed of magnets. Long dipole magnets are employed to bend and to contain the beam within a circular trajectory. Their field quality is usually tested by arrays of rotating coils. Typically the measurements must be affected by low uncertainty (+10) and the calibration of the sensing coils, in terms of surface and angle, is critical. In this paper,...

The paper analyzes, in brief, various on-line condition monitoring techniques for rotating electrical machines. The different failure mechanisms of electrical machines and several monitoring techniques are analysed. The advantages, disadvantages and reliability of each technique are underlined. A few of the current state of the art techniques are reviewed by surveying the latest developments in...
متن کاملModel Order Reduction for Rotating Electrical Machines
The simulation of electric rotating machines is both computationally expensive and memory intensive. To overcome these costs, model order reduction techniques can be applied. The focus of this contribution is especially on machines that contain non-symmetric components. These are usually introduced during the mass production process and are modeled by small perturbations in the geometry (e.g., ...
