1. The equivalent inductance and average magnetic conductivity of MS were involved in analysis of theory.

2. Further along, the influence of harmonic wave of magnetic conductivity of air gap and saturation of motor on wave pattern of wind electric current of micro-step driving was analyzed.

3. Epoxy glass cloth laminate for magnetic conductivity, with high mechanical strength, heat-resistance, with good magnetic permeability. suitable for making magnetic slot and wedge for motors.

4. It is shown that the microstructures, alloying element distribution and magnetic conductivity of P tude remarkably differ from those of S tube.

5. The important parameters for the wave absorption effects are electromagnetic loss factor, complex dielectric constant, complex magnetic conductivity.

6. Self-integral Rogowski current coil is used parallel sampling resistance in the out-port, and is selected the small magnetic conductivity copper or aluminum as the generatrix to be measured.

7. From the magnetic hysteresis loop-line, we can know some other parameters such as saturated magnetizing strength, magnetic conductivity, etc.
