cell phone jammer consists of integrated circuit | cellphone jammer ...

The inverse transform matrix must exist, their condition is a linear transformation coefficient determinant must be equal to zero, there is, the linear transformation coefficient determinant is not equal to zero (2). Transform relations: how to choose the transform relations These transform coefficients, various methods should be, as the case may be. how to choose the transform coefficients can have a variety of methods, as the case may be from the physical point of view, there is an intrinsic link between the old and new variables . Motor, from the physical point of view, between the old and the new variables is an intrinsic link. Motor in terms of mechanical and electrical energy by electromagnetic transmission, the coordinate transformation should be kept constant. Mechanical and electrical energy by electromagnetic transmission, the coordinate transformation should be kept constant.?? cell phone jammer???? has another feature of high cost performance.? Such as the iA, iB, iC on behalf of the windings of the three-phase current, it produces a magnetic field, a new variable i represents the winding three-phase current, it produces a magnetic field, new variables X, iY, the iZ on behalf of another phase two-phase winding current can produce the same magnetic field. Three representatives of the other multiphase (two phase winding current can produce the same magnetic field. Two-phase) winding current case, the mutual inductance between phase and phase column equations trouble: relative to the case, phase and white mutual inductance, the column equations trouble: two-phase system, its winding axis is perpendicular to each other, no mutual inductance, simple equations, usually 3 ? 2 transform. 3 ? 2 variable transformation. Axis perpendicular to each other, no mutual inductance, simple equations, usually a zero sequence component of a transformation to change and transform the physical meaning of the original number of turns per phase, three-phase winding W, A, B, C, with a per phase turns , three-phase winding with a number of turns per phase 2/3W difference in spatial magnetic axis 90 ? X, Y, b, instead of two-phase winding.The fifth characteristic of??? cell phone blocker is the accordance with the characteristics of Chinese mobile communication. X-axis and three-phase winding of the two-phase winding instead. Two-phase winding axis and three-phase winding A-phase axis difference between the angle ?, as shown in Figure Figure: phase winding axis of the difference between Y-a of ? xcb in the X axis, iX generated magnetic potential, the shaft, resulting in the magnetic potential 3/2Wix shall be equal to (4) 3-2 coordinate transformation axis coordinate transform A and B, three-phase winding current generated by the magnetic potential in the axial three-phase winding current magnetic potential in the X-axis, The magnetic potential on the projection of the current three-phase winding, which is the first relation (25).??? cell phone jammer????? has fully considered the detailed situation of mobile communication network in whole machine design and function setting.Second relationship representation of the magnetic potential generated by the second relationship on behalf of y i generated by the magnetic potential 3/2WiY type should be equal to A, three-phase winding current generated by the magnetic potential in the three-phase winding current magnetic potential Y axis of the projection should be equal to the magnetic potential in the current three-phase winding axis projection LL inverse transform of: inverse transformation (26) in the motor theory, according to the occasions, the use of different commonly used three different motor theory, according to the occasions, the use of different commonly used three different X-, Y-coordinate system: a coordinate system, X-, Y-axis in space, stationary, and so that the axis and three-phase coordinate system axis, the axis in space and the X-axis stationary stationary in space and three-phase coordinate system axis,The covering radius of?? ?? cell phone jammer is large enough. the axis coincides with the A axis of the three-phase coordinate system, coordinate system, axis variable and A, coincide, ie, ? = 0, known as alpha ? coordinates, alpha, beta-axis variable, B, C, axis between the old variables have the following relationship: the axis of the old variables have the following relationship between beta B or: (28) in accordance with the conditions.
