112 are arranged between two ply of papers 113 with sandwich formats.In these ply of papers 113 embodiment as shown here in the same manner
Construction.The second ply of paper 113 is also impregnated with resin and/or applied with resin in other words.Then it is adjacent with the second ply of paper 113 to be
Pawl pole 22.This external applicationRepresent the electric field formed in the case of energization.Each ply of paper 113 forms one in this case
Electric fieldThe electric fieldTherefore separated by the section 112 of conduction.Each electric field in Fig. 4 cDirection of an electric field pass through corresponding arrow
Head represents.A reference line is from reference for purposes of illustrationTowards the arrow extension of explanation direction of an electric field.Adjusted connecting
Electric field is built respectively during device FETThe electric fieldBuilt between beam combination (rotor windings) 51 and pawl pole 22.But the structure
Electric fieldWith the field strength significantly smaller than in the case of the claw pole electric generator of routine, because the very low electricity of conductive layer 112a
Resistance it is connected to ground.Therefore potential balance is had occurred and that between rotor windings 51 and layer 112a when connecting adjuster FET.Cause
This only one has the electric field of very small field strengthActed in pawl pole so that structure one is substantially reduced in pawl pole 22
Voltage.The voltage curve compared with the claw pole electric generator of routine when connecting claw pole electric generator is shown in figure 4d.According to figure
Show that obviously the voltage curve 120 in the case of conventional claw pole electric generator has strong voltage pulsation.On the contrary, the solution of the present invention
Scheme has the voltage curve 121 for having virtually no voltage pulsation.Transverse axis represents chronomere.The longitudinal axis represents voltage.
Fig. 5 illustrates the different accesses of the exciting circuit controller in the case of motor 10 with schematical circuit
State.Fig. 5 a show the current trend I in the case where being powered to field coil in this case.Fig. 5 is shown generally at H bridges
Structure.The parallel circuit of two branch roads is shown in this case, inherently gone here and there in these branch roads between operating voltage Ub
Join two semiconductor elements.Current potential between the semiconductor element of series connection, which is exported, gives excitation winding.Replaced according to the present invention logical
The high side adjuster (High-Side-Regler) often used uses the circuit of H bridges or class H bridges.It is additional thus, it is possible to realize
Function.The normal operation of additional function is shown without in Fig. 5 a and Fig. 5 b.Show what magnetizing coil was powered in fig 5 a
After situation, the situation of idle running is shown in figure 5b.Describe the additional of repid discharge (Schnellentladung) in fig. 5 c
Function.It can realize that the Rapid reversal around beam combination or field winding excites using the circuit.Two coil connecting terminal are herein
Relative to conventional operation reversal connection.By significantly changing relative to idle running situation for eliminating the method for operation of exciting current and can obtain
Kind dynamic characteristic.The energy that ball bearing is introduced in the case where Rapid reversal excites is limited by the size of rotor ability.
This energy power restriction is not present in the case of repid discharge, because contact is now not present between ground connection slip ring and axle.Institute
It is such slip ring in this case to state ground connection slip ring, and it has relative to the smaller of ground in the case where being powered to field coil
Voltage difference.The contact of the conductive layer 112 of seal 100/ is shown specifically in figure 5d.Slip ring is in normal operation, Yi Ji
There is ground potential in the case of energization and in the case of idle running.The contact with being grounded slip ring is real by the conductor rail of each slip ring
It is existing.Circuit with H bridges is also referred to as 4 quadrant adjusters.Current trend is by connection terminal UbPass through carbon brush with high switch segments
Pass through the seal 100 with integrated guiding device 110 towards around beam combination 51 or excitation winding 51 with the first slip ring 72
The slip ring 72 and affiliated carbon brush 140 for continuing through another pole are grounded.In the current trend that dallies in the case of (Fig. 5 b) as circle
Continued from excitation winding 51 by high part H towards lower part L and return to excitation winding 51.In the case of quick de-regulation
Current trend is realized by diode D.Carried out soon in this case through being powered relative to normal condition reversal connection connection terminal
Speed electric discharge (Fig. 5 a).Working voltage U on ground wire in this case be presentb。
