There are the differences on magnetic circuit with 10 relative position of rotor with A2.When position as shown in Figure 1, such as assume to concentrate armature winding A1 at this time
In magnetic linkage be approximately zero, referred to as the first equilbrium position concentrates the magnetic linkage in armature winding A2 to be also approximately at zero at this time, due to collection
Middle armature winding A2 is different from the position of A1 relative rotor, differs half of rotor polar distance, therefore the position is known as the second balance position
It sets.During one electrical cycle of rotation counterclockwise of rotor 10, A phase concentrates magnetic linkage amplitude change procedure in armature winding A1
Are as follows: the first equilbrium position --- positive maximum amplitude --- the second equilbrium position --- negative maximum amplitude --- first equilbrium position；
And A phase concentrates magnetic linkage amplitude change procedure in armature winding A2 are as follows: the second equilbrium position --- positive maximum amplitude --- first is flat
Weighing apparatus position --- negative maximum amplitude --- second equilbrium position.Therefore, the magnetic linkage variation tendency in two parts armature winding is symmetrical
It is complementary.It is all bipolarity magnetic linkage (that is, have just have negative) that A phase, which concentrates the magnetic linkage generated in armature winding A1 and A2, this feature and is passed
The double salient-pole electric machine of system is different.A phase concentrates the counter potential waveform generated in armature winding A1 and A2 also to have symmetry, series connection group
After A phase winding, harmonic component is cancelled out each other, and obtained opposite potential has preferable sinuso sine protractor, is turned to reduce
Square fluctuation is highly suitable for brushless ac (BLAC) control.
B, C two-phase equally have the characteristics that A phase, 120 ° of electrical angles of phase mutual deviation between three-phase.
