This paper presents a current sensor based on fluxgate principle, which consists of a cylinder-shaped amorphous core with a U-shaped magnetic gathering shell. In the designed sensor, the exciting winding and secondary winding are arranged perpendicularly so that the magnetic fields produced are mutual orthogonally, that is, the exciting magnetic field and the feedback magnetic field is decoupled....
A SIPMSM (Surface-interior permanent magnet synchronous motor) is a new type of PMSM [1-2], it differs from traditional SPMSMs (Surface permanent magnet synchronous motor) and IPMSMs (Interior permanent magnet synchronous motor) in that the main magnetic field of it is created jointly by SPMs (Surface permanent magnet) and IPMs (Interior permanent magnet). The existence of the PM slots in the rotor...
The shunt reactors are important components in the EHV/UHV (Eltra/Ultra High Voltage) power systems used for the voltage regulation issues. One of their important roles is to compensate the reactive power. Typically for such compensation the fixed shunt reactors are used. Alternative concepts introduced recently are the controllable reactors. The controlling effect of orthogonal flux type controllable...
The crystal structures and magnetic properties of (Fe0.6-Co0.4)100-XMx (M=Ti, V, Zr, Nb, Y, Cu, Pt, Al, Si, Ge, X=0 to 10) alloys annealed at 900??C were investigated. The crystal structures were bec for M=V, Nb, Y, Cu and Pt, a mixture of bec and fcc for M=Ge with X=2 to 4, and bec plus unidentified structures for M=Ti and Zr. The saturation magnetic flux density Bs decreases sharply for M=Ti, Nb...
