High-speed Brushless DC Motor Core Loss Calculation Model
Core loss is caused by the Alternating magnetic field and magnetic field of the magnetic field in ferromagnetic materials.
The main factors that affect flux density is the ferromagnetic materials, the air-gap thickness of pump body, length, etc.

Introduction
For half a century, combustion synthesis [1] has been used to fabricate a large range of materials
under the form of powders or near-net shape products [2].
The Time-resolved X-ray diffraction experiments were performed on the Material Science Beamline ID11 at the European Synchrotron Radiation Facility, Grenoble, France.
Thanks to the surrounding liquid, which increases the contact surface area and, consequently, the material transfer, the TiC particles continue to grow.

Solution-treated material was desired for this study in order to attempt to understand the effects of cyclic strain.
Material aged to contain coarse precipitates would contain little remaining copper in the aluminum matrix, and thus a very low driving force for any precipitation during testing.
Solution-treated material presented a clean slate with respect to precipitation, allowing for simple comparison of precipitation at different testing conditions, a high driving force for precipitation, and a tendency to strain more homogenously than material containing fine precipitates.
Material was received in this condition and cold rolled to 7 mm, following which standard “dog-bone” specimens were machined from the rolling direction.

Materials and Methods
In this study, three kinds of patterned wafers have been used in order to investigate the pitting dependence on the dry etch/ passivation/wet cleaning combination:
-- SiO2 passivation etch landing on AlCu
-- Vias etch landing on AlCu
-- AlCu pad patterning
Passivation etch has been performed on a Lam 4520XL tool, a dual-frequency (2 and 27MHz) capacitively coupled RF plasma etching system.
Via etch has been performed on a TEL 85 DRM tool, a dielectric materials etching system equipped with a 13.56 MHz RF source and a dipole ring magnetron in order to ensure good uniformity.
Figure 4: Scheme of the etched layers during vias etch In this case an acidic (pH=1 without F-) product was used both due to the compatibility with other materials exposed and to the removal efficiency of post etch residues.

However the current materials and the problems of manufacture with the standards of performance justify the impossible application of this type of system in the blades turbine.
