The opposite of magnetic permeability is " magnetic reluctance ".
2.
This is the position of maximum magnetic reluctance for the rotor pole.
3.
Torque is generated through the phenomenon of magnetic reluctance.
4.
Crankshaft position and speed are determined by input signals generated by poles in a magnetic reluctance disc.
5.
Since the permanent magnets in a PM machine already introduce considerable magnetic reluctance, then the reluctance in the air gap and coils are less important.
6.
This maps magnetic reluctance to electrical resistance, resulting in magnetic flux mapping to current instead of magnetic flux rate of change as required for compatible variables.
7.
The primary advantage of the gyrator-capacitor model compared to the magnetic reluctance model is that the model preserves the correct values of energy flow, storage and dissipation.
8.
Magnetic permeance \ mathcal { P } is defined as the reciprocal of magnetic reluctance \ mathcal { R } ( in analogy with the reciprocity between electric conductance and resistance ):
9.
All this is done to minimize magnetic reluctance of the magnetic circuit which the magnetic field created by the rotor coils travels through, something which is important for optimizing these machines.
10.
Similarly, the commonly seen analogy using mmf and magnetic flux as the fundamental variables, which gives rise to the concept of magnetic reluctance, does not correctly model energy flow.
