Simply, torque/electric current than it is big, be suitble to the advantages that high-speed cruising, but in the presence of air-gap field can not be adjusted and while breaking down exists
The problem of demagnetization difficulty.Therefore, electric excitation biconvex electrode electric machine (DSEM) is derived on the basis of doubly salient permanent magnet motor, when fixed
When rotor pole arc length meets certain relationship, total air-gap permeance of double salient-pole electric machine is steady state value, at this time Exciting Windings for Transverse Differential Protection operating point
It will not change with the rotation of rotor, therefore double salient-pole electric machine does not have a location torque when static, on double salient-pole electric machine winding
Interlinkage flux is only directly proportional to magnetic conductance.When being run as generator, output electricity can be easily adjusted by adjusting exciting current
Pressure when as motor running, has many advantages, such as direct current generator operational efficiency height, good speed adjustment features.
